On the other hand, between reactive tank 7 and sludge sump 8, be provided with and make the 1st sludge pipe 43 that is provided with on the reactive tank 7 provide the 2nd sludge pipe 44 of primary sludge water or a sewage to be communicated with or the described groove switching valve 45 of its cut-out with trommel 11 in sludge sump 8.On this groove switching valve 45, connect again from the water receptacle sewage of 38 discharges of trommel 11 or the 3rd sludge pipe 46 and the 4th sludge pipe 47 that is connected with described hand-line reel drum 9 of secondary sewage.In the figure, express described stop valve 80 is set on the 3rd sludge pipe 46, on described the 4th sludge pipe 47, be arranged on the pressurizing valve 49 of sealing when pressurizeing in the container 5, the auxiliary aspirating valve 98 that auxiliary suction tube 97 is set and opens and closes this auxiliary suction tube 97 between this pressurizing valve 49 and above-mentioned groove switching valve 45.And be provided with on the top of above-mentioned sludge sump 8 to this sludge sump 8 and suck the air suction valve 48 that air are used, at the mud suction tube 51 that is provided with on the above-mentioned hand-line reel drum 9 till extending to purification tank 50.

Connect agglutinant supply-pipe 55 again on described the 1st sludge pipe 43, this agglutinant supply-pipe 55 is connected with agglutinant container 12 by agglutinant valve 56.When agglutinant is provided, open and close agglutinant valve 56 with manual or automated manner, the agglutinant of necessary amount can be provided in the reactive tank 7 of decompression from agglutinant container 12 like this.

Adopt these structures, can as described belowly work.When groove switching valve 45 is switched to the sludge sump position d on illustrated right side, the 4th sludge pipe 47 is communicated with the 2nd sludge pipe 44, the 3rd sludge pipe 46 is communicated with the 1st sludge pipe 43, if under this state, make decompression in the reactive tank 7, then by the 1st sludge pipe the 43, the 3rd sludge pipe 46, sludge sump 8 internal pressures are reduced, and by the 2nd sludge pipe the 44, the 4th sludge pipe 47, mud suction tube 51, primary sludge water are attracted to trommel 11 in the sludge sump 8 from purification tank 50.With trommel 11 sewage that sludge components separates is attracted to reactive tank 7 from water receptacle 38 by the 3rd sludge pipe the 46, the 1st sludge pipe 43 then.Again, if groove switching valve 45 is switched on the reactive tank position f in illustrated left side, then the 1st sludge pipe 43 is communicated with the 4th sludge pipe 47, and the 2nd sludge pipe 44 is communicated with the 3rd sludge pipe 46.In this state, reactive tank 7 forms the state that is communicated with atmosphere by the 1st sludge pipe 43 and auxiliary suction tube 97.If groove switching valve 45 is switched to illustrated intermediary 2 groove link position e, then the 1st sludge pipe 43 is communicated with the 2nd sludge pipe 44, and the 3rd sludge pipe 46 is communicated with the 4th sludge pipe 47.If under this state to the internal pressurization of reactive tank 7 and sludge sump 8, is communicated with mud suction tube 51 by the 3rd sludge pipe 46 and the 4th sludge pipe 47 in the sludge sump 8, so the interior sewage of reactive tank 7 is pressed to the interior trommel 11 of sludge sump 8 by the 1st sludge pipe 43 and the 2nd sludge pipe 44.

Again, the bottom of sludge sump 8 is provided with outlet valve 53, by opening the 8 interior pressurizations of 53 pairs of sludge sumps of this outlet valve, the mud that are detained in the sludge sump 8 is discharged to by mud vent pipe 52 handles field 54.

And, in the sludge concentration device 20 of this example, possess the washing unit 59 that the water in the described water tank 16 is ejected from nozzle 58 with water pump 57.By means of this washing unit 59, can the cleaning groove 50 inner or wash one's hands for the operator.

Said pump 22 hydraulic motors 40 grades are arranged at the bottom of container 5 at the rear portion of the officer's seat 2 shown in Fig. 1,2.In shown in Figure 7 each constituted, the member that has occurred in Fig. 1,2 was with being marked with the symbol that uses among Fig. 1,2.

Fig. 8 is the action figure of the structure of piping diagram shown in Figure 7.As shown in Figure 8, utilize the attraction and the spissated main mud collection work of the purification tank mud that above-mentioned sludge concentration device 20 carries out, have that the attraction of primary sludge water, agglutination reaction, logical atmosphere, mud concentrate, outlet valve is discharged this five work.In Fig. 8, the internal pressure of the operational stage of each valve and sludge sump 8 and reactive tank 7 with these work and when carrying out these work, have or not these situations of sludge water to gather with the table look-up form.Followingly the details of the work on each hurdle is described according to Fig. 9～Figure 13.

Fig. 9 is the piping diagram of the primary sludge water among the action figure shown in Figure 8 when attracting, Figure 10 is the piping diagram when carrying out agglutination reaction in the reactive tank among the action figure shown in Figure 8, Figure 11 is the piping diagram when atmosphere opening among the action figure shown in Figure 8, Figure 12 is the piping diagram of the mud among the action figure shown in Figure 8 when concentrating, and Figure 13 is the piping diagram when outlet valve is discharged among the action figure shown in Figure 8.

As shown in Figure 9, when attracting primary sludge water, the front end of mud suction tube 51 inserts in the purification tank 50, and pressurizing valve 49 is opened, and auxiliary simultaneously aspirating valve 98 is closed, and groove switching valve 45 is switched to sludge sump position d, attracts switching valve 25 to be switched to and attracts position a.Then, by driving pump 22, the air of extracting out in the reactive tank 7 makes decompression in the reactive tank 7.By means of this, by 46 decompressions of the 1st sludge pipe the 43, the 3rd sludge pipe, by the 4th sludge pipe 47 and the 2nd sludge pipe 44, primary sludge water is attracted to the trommel 11 that is provided with in the sludge sump 8 in the sludge sump 8 from mud suction tube 51.The primary sludge water that this is attracted falls sludge components by means of the screen cloth main body 69 of trommel 11 is separated, separatedly falls the sewage that sludge components stays and attracted to reactive tank 7 from water receptacle 38 by the 3rd sludge pipe 46 and the 1st sludge pipe 43.Here it is attracts from mud suction tube 51 primary sludge water in sludge sump 8, utilize above-mentioned trommel 11 to separate the path of sludge components and the sewage that will separate sludge components with this trommel 11 is attracted to path in the reactive tank 7 in the sludge sump 8.In this operation, mud is stranded in the sludge sump 8, and one time sewage is stranded in the reactive tank 7.

By means of this operation, the primary sludge water that is attracted in the container 5 once filters, and dregs in the purification tank 50 and precipitating sludge etc. store in sludge sump 8 from trommel 11, has only through trommel 11 filtering sewage to attracted to reactive tank 7.The attraction of the primary sludge water that carries out by means of this operation is to attract function, dregs and precipitating sludge can be attracted to sludge sump 8 expeditiously.And by means of this once attract the operation, primary sludge water and the few primary sludge water of sludge components that sludge components is many can both pass through trommel 11, only sludge components is stored expeditiously in sludge sump 8, can be only will be attracted to reactive tank 7, and therefore can carry out the attraction of primary sludge water and separating of sludge components continuously expeditiously through a filtering sewage once.

Again, come out to store the amount that in a single day sludge components in sludge sump 8 reaches regulation by means of this operation from the primary sludge water sepn, shown in Fig. 6 C, the float 86 of stop valve 80 is just upwards pushed away, be positioned at locational brake pad 87 side shifting downstream of the opening 82 of dividing plate 83 after axis of rocking 85 rotates, leave opening 82.By means of this, the ball 84 that is arranged at body 81 inside is stopped up opening 82 fully by a sewage thruster downstream, and a sewage in the 3rd sludge pipe 46 stops to flow.In case flowing of a sewage in the 3rd sludge pipe 46 stops like this, the pressure in the sludge sump 8 and the pressure of purification tank 50 sides become same normal pressure, therefore in sludge sump 8, attract the action of primary sludge water to stop from mud suction tube 51, in sludge sump 8, attract the action of mud to stop.If these stop valve 80 actions are exactly the state that stores the mud of maximum in the sludge sump 8, can easily maximally utilise the high efficiency mud collection work of the capacity of sludge sump 8.

Also have, when carrying out this operation, even attract the operation of switching valve 25 wrong, to pressurization in the reactive tank 7, also because from the sewage of the 1st sludge pipe 43 to the 3rd sludge pipe 46 force feeds, the ball 84 of stop valve 80 has prevented the countercurrent flow of sewage with opening 82 sealings of the dividing plate 83 of upstream side.

As shown in figure 10, when a sewage generation agglutination reaction that is attracted to reactive tank 7, the pressurizing valve 49 of the 4th sludge pipe 47 is closed, and the auxiliary aspirating valve 98 of auxiliary suction tube 97 is opened simultaneously, and groove switching valve 45 is switched to reactive tank position f.Attract switching valve 25 to be positioned at and attract position a, by the air in the driving pump 22 attraction reactive tanks 7.By means of this, attract air in reactive tank 7 from auxiliary suction tube 97, with the sewage (aeration) in the pneumatic blending reactive tank 7.Here it is attracts air, the path of a sewage in the stirred tank 7.Again, open agglutinant valve 56, the agglutinant of specified amount is attracted in the reactive tank 7 from agglutinant container 12.The amount of this agglutinant is according to factors such as the amount decision that is attracted to a sewage in the reactive tank 7.Like this, provide the laggard line space gas mixing of agglutinant to mix to sewage in the reactive tank 7, seek to promote the agglutination reaction of a sewage, the sludge components in sewage forms bulk.When carrying out this operation, be to have mud in the sludge sump 8, there is the state of a sewage in the reactive tank 7.

As shown in figure 11, when leading to atmosphere, groove switching valve 45 switches to reactive tank position f, attracts switching valve 25 to be switched to middle positive position b.Again, the air suction valve 48 of sludge sump 8 also is opened.By means of this, the 3rd blast main 33 of reactive tank 7 is communicated with to atmosphere opening with atmosphere opening pipe 26 by the 2nd blast main 32.Again, the 1st sludge pipe 43 of reactive tank 7 can lead to atmosphere by the auxiliary aspirating valve 98 of auxiliary suction tube 97.In this example, auxiliary suction tube 97 1 sides make reactive tank 7 logical atmosphere, but also can open the pressurizing valve of the 4th sludge pipe 47, make reactive tank 7 logical atmosphere in the 4th sludge pipe 47 1 sides.And sludge sump 8 is by air suction valve 48 logical atmosphere.These make in the reactive tank 7 and open to atmosphere path in the sludge sump 8 exactly.When carrying out this operation, be in the sludge sump 8 mud to be arranged, the state of sewage once in the reactive tank 7.

As shown in figure 12, carrying out mud when concentrating, groove switching valve 45 is switched to groove link position e, attracts switching valve 25 to be switched to pressing position c.The auxiliary aspirating valve 98 of auxiliary suction tube 97 and the air suction valve 48 of sludge sump 8 are closed, and the pressurizing valve 49 of the 4th sludge pipe 47 is opened.By means of this, the water receptacle 38 that is provided with on the trommel 11 of sludge sump 8 is by the 3rd sludge pipe 46 and groove switching valve the 45, the 4th sludge pipe 47, and the mud suction tube 51 that is inserted into purification tank 50 with front end is communicated with.Then,, suck atmosphere by attracting switching valve 25 to pump 22, in reactive tank 7 He in the sludge sump 8, provide forced air by attracting switching valve 25 from this pump 22 from atmosphere opening pipe 26 by driving pump 22.At this moment, as mentioned above, be communicated with purification tank 50 under the normal atmosphere in the sludge sump 8, a sewage in the therefore pressurized reactive tank 7 is pressed to trommel 11 in the lower sludge sump of pressure 8 by the 1st sludge pipe 43 and groove switching valve the 45, the 2nd sludge pipe 44.A sewage that is pressed to this trommel 11 separates sludge components by the mesh screen main body 69 of trommel 11.In this operation, a sewage in the reactive tank 7 is pressed in the sludge sump 8, forms the state that does not have a sewage in the sludge sump 7.

By means of this operation, carry out secondary filtration for a sewage, the blocky sludge components after reactive tank 7 carries out agglutination reaction is stored in sludge sump 8 from trommel 11.Here it is by means of the concentrating function as thickened sludge composition the sewage of trommel 11 in reactive tank 7 of mud separation means.Again, through trommel 11 filtering secondary sewage is the water of further removing sludge components from a sewage again, therefore from water receptacle 38 through the 3rd sludge pipe 46, groove switching valve 45 and the 4th sludge pipe 47, discharge as the water storage of purification tank 50 from mud suction tube 51.Here it is with secondary sewage from the path of mud suction tube 51 to the outside discharge.

Again, because this operation, from a sewage, separate, store blocky sludge components in sludge sump 8 when reaching specified amount, shown in Fig. 6 C, the float 86 of stop valve 80 is upwards pushed away, and axis of rocking 85 rotates, be positioned at locational brake pad 87 side shifting downstream of the opening 82 of dividing plate 83, leave opening 82.Therefore, the ball 84 that is arranged on body 81 inside is pushed to the downstream side by sewage, and whole opening 82 is stopped up, and the secondary sewage in the 3rd sludge pipe 46 stop to flow.Like this, the flowing in case be stopped of the secondary sewage in the 3rd sludge pipe 46, the pressure in the sludge sump 8 is just identical with pressure in the reactive tank 7, so force feed mud can stop in sludge sump 8.In case 80 actions of this stop valve store in sludge sump 8 under the state of mud of maximum, can easily effectively utilize the high efficiency mud collection work of the capacity of sludge sump 8 to greatest extent.

Also have, when carrying out this operation, even attract switching valve 25 operations to make a mistake, make decompression in the reactive tank 7, by the 1st sludge pipe 43 and 44 decompressions of the 2nd sludge pipe, the opening 82 of the dividing plate 83 of the ball 84 sealing upstream sides of stop valve 80 can prevent counter-current of sewage in the sludge sump 8.

As shown in figure 13, during from outlet valve 53 discharges, handling field 54, groove switching valve 45 switches to reactive tank position f, attract switching valve 25 to be switched to pressing position c, the pressurizing valve 49 of the 4th sludge pipe 47 and the auxiliary aspirating valve 98 of auxiliary suction tube 97 are closed, and outlet valve 53 is opened.Then, by driving pump 22, suck atmosphere by attracting switching valve 25 to pump 22 from atmosphere opening pipe 26, pass through to attract switching valve 25 and the 2nd blast main 32 from this pump 22, in reactive tank 7, in sludge sump 8, provide forced air from the 3rd blast main 33 from the 4th blast main 34.At this moment, pressurizing valve 49 and auxiliary aspirating valve 98 are closed, so are closed in the reactive tank 7, only provide forced air in sludge sump 8, by means of this forced air, the mud that is stored in the sludge sump 8 is discharged to processing field 54 from outlet valve 53 by mud vent pipe 52.Can seek reliably the mud in the sludge sump 8 to be discharged by means of this operation, in sludge sump 8, form no mud state.

The above is the details of above-mentioned action shown in Figure 8, the a series of mud recovery operation of being undertaken by such operation, can easily carry out by the opening and closing operations etc. that the container back that concentrates car 1 from the mud shown in above-mentioned Fig. 1,3 is implemented each valve 25,45,48,49,53,98, therefore stop and under the state of road left end, can carry out the mud collection work expeditiously making mud concentrate car 1.

Also have, in above-mentioned example, the sludge water that attracts purification tank 50 is carried out spissated example to be illustrated, but for example, if the few primary sludge water of solids component, then also groove switching valve 45 can be switched to reactive tank position f, directly attract to reactive tank 7, various operations such as the attraction of mud are not limited to the various work of above-mentioned explanation.

On the other hand, between reactive tank 7 and sludge sump 8, the described groove switching valve 45 that makes the 1st sludge pipe 43 that is provided with and the 2nd sludge pipe 44 that the trommel in the sludge sump 8 11 is provided primary sludge water or a sewage be communicated with or cut off is set on reactive tank 7.On this groove switching valve 45, connect again from the water receptacle sewage of 38 discharges of trommel 11 or the 3rd sludge pipe 46 and the 4th sludge pipe 47 that is connected in above-mentioned hand-line reel drum 9 of secondary sewage.On described the 4th sludge pipe 47, be arranged on the pressurizing valve 49 of closing when pressurizeing in the container 5, between this pressurizing valve 49 and above-mentioned groove switching valve 45, the auxiliary aspirating valve 98 of the end of auxiliary suction tube 97 and this auxiliary suction tube 97 of switching be set.And the mud suction tube 51 extend to purification tank 50 is set on above-mentioned hand-line reel drum 9.

Again, connect agglutinant supply-pipe 55 on above-mentioned the 1st sludge pipe 43, this agglutinant supply-pipe 55 is connected with agglutinant container 12 by agglutinant valve 56.When agglutinant (aggegation liquid) is provided,, can be attracted in the reactive tank 7 of decompression from the agglutinant of agglutinant container 12 with necessary amount by opening and closing agglutinant valve 56 with manual or automated method.More air suction pipe 115 is set at agglutinant valve 56, on this air suction pipe 115 sniff valve 116 is set by a side of reactive tank 7 than this agglutinant supply-pipe 55.Can introduce atmosphere by sniff valve 116 from this air suction pipe 115.

If adopt these formations, can as described belowly work.If groove switching valve 45 is switched to the sludge sump position d on illustrated right side, then the 4th sludge pipe 47 is communicated with the 2nd sludge pipe 44, and the 3rd sludge pipe 46 is communicated with the 1st sludge pipe 43.Attract position a to make decompression in the reactive tank 7 if under this state, will attract switching valve 25 to switch to, then in the sludge sump 8 by 46 decompressions of the 1st sludge pipe the 43, the 3rd sludge pipes, primary sludge water attracted to trommel 11 in the sludge sump 8 by the 2nd sludge pipe the 44, the 4th sludge pipe 47, mud suction tube 51 from purification tank 50.Then, a sewage that separates sludge components by trommel 11 attracted to reactive tank 7 from water receptacle 38 by the 3rd sludge pipe the 46, the 1st sludge pipe 43.

At this moment, the pressurizing valve 49 of the 4th sludge pipe 47 is closed, on described auxiliary aspirating valve 98, connect short hose dimensions 111,, just can attract primary sludge water to be sent to trommel 11 expeditiously to the 4th sludge pipe 47 from auxiliary aspirating valve 98 if will open as the aspirating valve 98 of should assisting of operating portion.In this case, owing to utilize the resistance of short hose dimensions 111 pipe when attracting sludge water little, therefore can carry out mud attraction work with the short time.

If groove switching valve 45 is switched to two groove link positions of illustrated intermediary e, then the 1st sludge pipe 43 is communicated with the 2nd sludge pipe 44, and the 3rd sludge pipe 46 is communicated with the 4th sludge pipe 47.If under this state to the internal pressurization of reactive tank 7 and sludge sump 8, then be communicated with mud suction tube 51 owing to passing through the 3rd sludge pipe 46 and the 4th sludge pipe 47 in the sludge sump 8, so sewage in the reactive tank 7 are pressed to the trommel 11 of sludge sump 8 by the 1st sludge pipe 43 and the 2nd sludge pipe 44.

Rear end lower at sludge sump 8 is provided with outlet valve 53 again, pressurizes by opening in 53 pairs of sludge sumps of this outlet valve 8, and the mud that are detained in the sludge sump 8 are discharged into by short hose dimensions 111 and handle field 54.

Said pump 22 hydraulic motors 40 grades are arranged at the bottom of container 5 at the rear portion of the officer's seat 2 shown in Figure 14,15.The member that occurs among Figure 14,15 that respectively is formed in shown in Figure 17 is marked with the symbol that Figure 14,15 marks.

Figure 18 is the action figure in the structure of piping diagram shown in Figure 17.As shown in Figure 18, utilize above-mentioned sludge concentration device 120 to carry out the attraction and the spissated main mud collection work of purification tank mud, comprise that primary sludge water attraction (hand-line reel drum), primary sludge water attract (auxiliary aspirating valve), agglutination reaction, logical atmosphere, mud to concentrate (discharge of hand-line reel drum), mud concentrated (auxiliary aspirating valve is discharged), outlet valve is discharged 7 kinds.Among Figure 18 with the form of table look-up gathered these work, operational stage, the sludge sump 8 and the internal pressure of reactive tank 7 and having or not of sludge water of each valve when carrying out these work.The following details that describes the work on each hurdle according to Figure 19～25 in detail.

Figure 19 is the piping diagram of the hand-line reel drum from action figure shown in Figure 180 when attracting primary sludge water, Figure 20 is the piping diagram of the auxiliary aspirating valve from action figure shown in Figure 180 when attracting primary sludge water, Figure 21 is the piping diagram of the reactive tank in action figure shown in Figure 180 when carrying out agglutination reaction, Figure 22 is the piping diagram when atmosphere opening among the action figure shown in Figure 180, Figure 23 is the piping diagram during from hand-line reel drum effluent sewerage when mud concentrates among the action figure shown in Figure 180, Figure 24 is the piping diagram during from auxiliary aspirating valve effluent sewerage when mud concentrates among the action figure shown in Figure 180, and Figure 25 is the piping diagram of the outlet valve from action figure shown in Figure 180 when discharging.

As shown in figure 19, when attracting primary sludge water, the front end of mud suction tube 51 inserts in the purification tank 50, opens pressurizing valve 49 and closes auxiliary aspirating valve 98 simultaneously, and groove switching valve 45 is switched to sludge sump position d, attracts switching valve 25 to be switched to and attracts position a.Then,, attract the air in the reactive tank 7, make decompression in the reactive tank 7 by driving pump 22.By means of this, make decompression in the sludge sump 8 by the 1st sludge pipe the 43, the 3rd sludge pipe 46, primary sludge water is attracted to the trommel 11 that is provided with in the sludge sump 8 from mud suction tube 51 by the 4th sludge pipe 47 and the 2nd sludge pipe 44.The primary sludge water that this is attracted separates sludge components by means of trommel 11, and the separated sewage that falls of sludge components attracted to reactive tank 7 from water receptacle 38 by the 3rd sludge pipe 46 and the 1st sludge pipe 43.Here it is attracts primary sludge water from mud suction tube 51 in sludge sump 8, a sewage that separates the path of sludge components and will separate sludge components with this trommel 11 with described trommel 11 is attracted to the path in the reactive tank 7 in the sludge sump 8.This attraction work is in the position of purification tank 50 away from vehicle, the work under the situation that need attract with long mud suction tube 51.In this work, mud is stranded in the sludge sump 8, and one time sewage is stranded in the reactive tank 7.

On the other hand, when attracting this primary sludge water, described purification tank 50 is under the last situation of the closer distance of vehicle, as shown in figure 20, the flexible pipe 111 that is arranged at the short size at said vesse 5 rear portions is connected on the auxiliary aspirating valve 98 of the auxiliary suction tube 97 that the 4th sludge pipe 47 is provided with midway, the front end of this short hose dimensions 111 is inserted in the purification tank 50, close the pressurizing valve 49 that is provided with on the 4th sludge pipe 47.Then, by making decompression in the container 5, can in container 5, attract mud by auxiliary aspirating valve 98 from short hose dimensions 111.By means of this, the situation that is wound on the mud suction tube 51 on the hand-line reel drum 9 with utilization is compared, and can manage the less attraction operation of resistance, therefore can carry out mud attraction work with the short time.Like this, can carry out high efficiency mud attraction work according to the distance that attracts mud.

And, in this example, auxiliary aspirating valve 98 is arranged on the height location of subframe 4 of a side at container 5 rear portions, should assist aspirating valve 98 opening rearward simultaneously, therefore will lack the work that hose dimensions 111 is connected in this auxiliary aspirating valve 98 carries out easily, and can open and close auxiliary aspirating valve 98, carry out expeditiously primary sludge water is attracted to work in the container 5.In this example, sludge water is attracted to sludge sump 8 backs in reactive tank 7, attracts, but also can directly be attracted to reactive tank 7.

As this example, after sludge sump 8 attracts, attract to reactive tank 7 from this sludge sump 8, by means of this, the primary sludge water that is attracted to container 5 is once filtered by trommel 11, dregs in the purification tank 50 and precipitating sludge etc. are trapped in the sludge sump 8 from trommel 11, have only through trommel 11 filtering sewage to attracted to reactive tank 7.The attraction that utilizes the primary sludge water that this operation carries out is to attract function, can expeditiously dregs and precipitating sludge be attracted to sludge sump 8.And by means of once attracting operation, primary sludge water and the few primary sludge water of sludge components that sludge components is many all pass through trommel 11, can only sludge components be stayed in the sludge sump 8 expeditiously, can only incite somebody to action once a filtering sewage and be attracted to reactive tank 7, therefore can carry out separating of good primary sludge water attraction of efficient and sludge components continuously.

As shown in figure 21, when a sewage that is attracted to reactive tank 7 carried out agglutination reaction, the pressurizing valve 49 of the 4th sludge pipe 47 and the auxiliary aspirating valve 98 of auxiliary suction tube 97 were closed, and groove switching valve 45 is switched to reactive tank position f.Attracting switching valve 25 is to attract on a of position, by the air in the driving pump 22 attraction reactive tanks 7.Open agglutinant valve 56 then, the agglutinant of specified amount is attracted to (offering) reactive tank 7 from agglutinant container 12.The amount of this agglutinant is according to the amount decision that is attracted to a sewage in the reactive tank 7.Thereafter, the sniff valve 116 of air suction pipe 115 is opened in accordance with regulations at interval, air is attracted in the reactive tank 7 by the 1st sludge pipe 43 from suction tube 115, with a sewage aeration in the reactive tank 7.Have only at this moment sniff valve 116 to open.Here it is attracts the path of a sewage in agglutinant and the pneumatic blending reactive tank 7.Like this, provide agglutinant to carry out aeration simultaneously, seek to promote the agglutination reaction of a sewage, make the sludge components in the sewage form bulk a sewage in the reactive tank 7.When implementing this operation, forming sludge sump 8 has mud, the state of sewage once in the reactive tank 7.

As shown in figure 22, when leading to atmosphere, attract switching valve 25 to be switched to middle positive position b.With this change action interlock that attracts switching valve 25, the air cutoff valve 148 of sludge sump 8 is opened.By means of this, thereby the 3rd blast main 33 of reactive tank 7 is communicated with logical atmosphere by the 2nd blast main 32 with atmosphere opening pipe 26.Again, sludge sump 8 is communicated with atmosphere opening pipe 26 by the 5th blast main 114, air cutoff valve the 148, the 2nd blast main 32, thus logical atmosphere.When implementing this operation, forming in the sludge sump 8 has mud, the state of sewage once in the reactive tank 7.

As shown in figure 23, when mud concentrated, groove switching valve 45 switched to groove link position e, attracted switching valve 25 to be switched to pressing position c.The auxiliary aspirating valve 98 of auxiliary suction tube 97 is closed, and the pressurizing valve 49 of the 4th sludge pipe 47 is opened.By means of this, the water receptacle 38 that is provided with on the trommel 11 of sludge sump 8 is by the 3rd sludge pipe 46 and groove switching valve the 45, the 4th sludge pipe 47, and the mud suction tube 51 that inserts purification tank 50 with front end is communicated with.Then,, through attracting switching valve 25 atmosphere is attracted to pump 22, in reactive tank 7 He in the sludge sump 8, provides forced air through attracting switching valve 25 from this pump 22 from atmosphere opening pipe 26 by driving pump 22.At this moment in the sludge sump 8 as mentioned above, be communicated with the purification tank 50 under the normal atmosphere, therefore a sewage in the pressurized reactive tank 7 is pressed to the trommel 11 in the lower sludge sump of pressure 8 by the 1st sludge pipe 43 and groove switching valve the 45, the 2nd sludge pipe 44.A sewage that is pressed to this trommel 11 utilizes trommel 11 to separate blocky sludge components.With this operation a sewage in the reactive tank 7 is sent in the sludge sump 8, forms the state that does not have a sewage in the reactive tank 7.

By means of this operation, carry out secondary filtration to a sewage, the blocky sludge components after reactive tank 7 carries out agglutination reaction stores in sludge sump 8 from trommel 11.Here it is by means of the sewage of trommel 11 in reactive tank 7 as the mud separation means sludge components being carried out spissated concentrating function.Again, secondary sewage after process trommel 11 filters is owing to be the water of further removing sludge components from a sewage, therefore pass through the 3rd sludge pipe 46, groove switching valve 45 and the 4th sludge pipe 47 from water receptacle 38, discharge as the water storage of purification tank 50 from mud suction tube 51.Here it is with secondary sewage from the path of mud suction tube 51 to the outside discharge.It is exactly the work corresponding with the attraction work of above-mentioned Figure 19 that this mud concentrates work, is that purification tank 50 is on the position with some distance of vehicle with the work under the situation of long mud suction tube 51.

On the other hand, as above-mentioned shown in Figure 20, purification tank 50 is in from attracting under the situation of primary sludge water from auxiliary aspirating valve 98 on the vehicle closer distance, as shown in figure 24, the secondary sewage that separates block sludge components with trommel 11 is discharged as the overflow of purification tank 50 from the short hose dimensions 111 that is connected in auxiliary aspirating valve 98 by the 3rd sludge pipe 46, groove switching valve the 45, the 4th sludge pipe 47 and auxiliary suction tube 97 behind the water receptacle 38 that stores in sludge sump 8.

As shown in figure 25, during from outlet valve 53 discharges, handling field 54, short hose dimensions 111 is connected in outlet valve 53, attract switching valve 25 to be switched to pressing position c, the auxiliary aspirating valve 98 of the pressurizing valve 49 of the 4th sludge pipe 47, auxiliary suction tube 97 is closed, and outlet valve 53 is opened.Then by driving pump 22, from atmosphere opening pipe 26 atmosphere is attracted to pump 22 by attracting switching valve 25, by attracting switching valve 25 and the 2nd blast main 32, in reactive tank 7, in sludge sump 8, provide forced air from this pump 22 from the 4th blast main 34 from the 3rd blast main 33.At this moment, auxiliary aspirating valve 98 is closed, so is closed in the reactive tank 7, by means of the forced air that offers in the sludge sump 8, the mud that stores in the sludge sump 8 is discharged to processing field 54 from outlet valve 53 through too short hose dimensions 111.Mud in the sludge sump 8 can be discharged reliably by means of this operation, become no mud state in the sludge sump 8.

It more than is exactly the details of above-mentioned action shown in Figure 180, as mentioned above, the work that attracts primary sludge water is that the mud suction tube 51 by means of the hand-line reel drum 9 that is provided with on the sludge concentration device 120 shown in above-mentioned Figure 14,16 carries out, still carry out by means of the auxiliary aspirating valve 98 of short hose dimensions 111 from the rear portion setting of container 5, can suitably determine according to its working condition, can carry out expeditiously and the work of mud attraction rapidly accordingly of this situation.

Also have, in above-mentioned example, the sludge water that attracts purification tank 50 is carried out spissated example to be illustrated, but, if the primary sludge water that for example solids component is few, also can when above-mentioned Figure 19,20 primary sludge water is attracted, groove switching valve 45 be switched to reactive tank position f, directly primary sludge water is attracted to reactive tank 7, operations such as attraction mud are not limited to every work of above-mentioned explanation.

In above-mentioned example, concentrate car 1,100 for example is illustrated, but the present invention there is not separated mud to attract can use in the car (mud suction device) at container 5 yet with mud again.
