Technical field

The present invention relates to sludge modifying machine, in agricultural fishing village village draining treatment facility, large-scale merging treatment and purification groove etc. scale living drainage treatment facility, and the draining treatment facility of the middle water manufacturing facility of buildings such as hotel, golf course in, by in the liquid that is modified, cultivating light compositing bacterium, actinomycetes, milk-acid bacteria, wire bacterium and making its increase, not only help purification of water quality, and the raising of the conversion of bacterium phase and concentrated property makes the minimizing of processing sludge quantity, actinomycetes etc. that intrasystem foul smell is reduced.Because so that harmful microorganism reduces in the lump and its treating water carries out modification to the mode that the cultivation of fish, plant acts on effectively, so not only can make supervisor status good, and also there is contribution in tap water cause, organic farming agricultural, the breed fishery field that utilizes its treating water.

Background technology

At present, seek to drop into the draining of handling as a kind of bacillus of soil bacteria from various facilities, thereby not only carry out common purification of water quality, and prevent the method that stench takes place; Also seek to drop into the soil bacteria that becomes the fermentation of EM synthesis type, thereby equally not only carry out common purification of water quality, and prevent that stench from taking place, and reduces the generation of mud.But, use the treatment facility of these technology also very rare the whole country, major part is to use activated sludge process or the contact oxidation method of aerobism bacterium, recently, for realizing that denitrogenation, dephosphorization also adopt the example of circulation denitrogenation etc. to increase gradually, but with handling relevant microorganism all is the bacterium that sewage is for anaerobism, aerobism, and it is made of bacterium and protozoon, can not drop into soil bacteria from the outside again.

But no matter bacillus still is the EM bacterium, continues to drop into bacterium and become burden for facilities management person, also may bring the supply of material to interrupt such uneasiness.

In addition, coexistences such as the vorticella of bacillus and the bacterium that also is referred to as sewage system, zoogloea are used, and therefore, can not bring the minimizing that produces sludge quantity.

Summary of the invention

Therefore, it is the water surrounding of preferent species that the present inventor makes with the soil bacteria, predict treating water purify, prevent stench take place, make the generation of mud also to reduce so that the kill activity of harmful bacterium also high, therefore, not the method that adds the useful bacterium of above-mentioned such regular input, and add and have method as far as possible for a long time with the biological multiplying medium that is used to make the function that useful bacterium breeds.

When the biological multiplying medium that makes after the liquid that is modified contacts shaping continuously, do not wear and tear, destroy for making it, consider to need quiet as far as possible and gently contact, the round-robin liquid that is modified is taken out and drops into from top from the bottom of reactive tank.The whereabouts mouth that falls from top at the liquid that is modified is provided with tray, makes its dispersion.And then in the cage of the pars intermedia of being located at reactive tank the biological multiplying medium of filling, and wire netting is set thereon, make the liquid that is modified contact biological multiplying medium by it.With fall from top be modified liquid not directly the mode of contacting metal net the water surface in the reactive tank is always kept than metal net height.In addition, be taken into mouth to the centre of the take-off pipe on top air being set, make the mechanism of playing water according to the proportion differential pressure in the pipe from described bottom.Thus, can be made as the device that the liquid that is modified is moved from bottom to top, and also can have and to keep the function of aerobism in the groove.Be implemented in that described tray disperses, also the wave when being distributed to the water surface etc. is taken into oxygen to liquid.

By making the mechanism that contacts with biological multiplying medium soft as far as possible, can reduce it thus and change frequency.

And, by existing treatment system that this sludge modifying machine of the present invention is packed into, can expect the high efficiency of sewage disposal.Particularly, the foul smell in the facility is reduced, the generation of mud is reduced.Because the kill activity height of harmful bacterium, so, can realize agricultural chemicals, antibiotic alleviating by treating water is supplied with to Organic farming, breed fishing ground.

For foul smell,, and also can supply with treating water for the place that stenches such as herding farmers' and school lavatory become problem not only in the facility.

Embodiment

Below, the present invention will be described in more detail.The 1st, sludge modifying machine of the present invention, from structure, has following mechanism, at first as shown in Figure 1, send air from gas blower 3 to air riser pipe 2, from suction port 4 be taken into be modified liquid since the proportion of the water of air suction inlet 5 tops reduce, thereby the liter waterborne in the pipe returns in the machine once more from 6.

This method is often used as the mud abstracting method of settling bath, therefore, even the liquid that concentration is high slightly can be not inaccessible yet, form upwelling and the interior katabatic drainage of machine in the pipe, make to continue circulation in the machine and remain on aerobic state, make the useful soil bacteria that comprises in the liquid that is modified breed efficiently and in machine, accumulate.

Modification liquid is fetched to outside the machine as 10 by outlet pipe 9, the unboiled water concentrated flow inlet and the Flow-rate adjustment groove of the ground investment subject facility that breaks it into two.Carrying to unboiled water concentrated flow inlet is in order to alleviate the rancid of unboiled water and with the modification of filtering net dirt settling, deodorizing.Carry the useful bacterium before being to make it in for treatment process afterwards to play a role to the Flow-rate adjustment groove, improve its effectiveness.

Flow out the back and extract mixed solution from the aeration tank of main body facility immediately, it is sent in the machine from inflow pipe 7, behind the answer liquid level originally pump is stopped, returning original running condition once more by pump 12.

For improving the cycle efficiency in the main frame and will remaining on sufficient aerobic conditions in the machine, utilize the air that supplies to air riser pipe 2, risen in pipe by upgrading liquid 20, in the 6 inflow machines of top.Thus, katabatic drainage 30 takes place, it arrives the bottom by taking in 8 of biological multiplying medium, becomes upwelling once more.

For aeration tank mixed solution inflow portion 7, tray is set as mentioned above, make current disperse to realize being taken into of air, reduce impact to biological multiplying medium.For same purpose, tray also is set in bottom from the spout 6 of the air riser pipe of this facility.

Therefore the air riser pipe, rarely has at the machine inner bottom part to produce the situation that mud retains with 1 group of 4 formation.To rise the efficient of pump of liquid low though carry out air, as the propulsion source that is used to produce katabatic drainage, compares not a halfpenny the worse with other method.

In main frame, take in the container 8 of biological multiplying medium in the central part configuration.Textural, so that the form of the modifying machine plane quartern is fixedly born platform at cell wall.Settle loam cake with the form of the same quartern thereon, it is the unfixing structure that can take out.Bear platform and on cover and settle the net fix 5～15mm mesh width.The net that bears platform is for taking out the structure of a part.

As biological multiplying medium, mainly use with the material of vegetalitas vegetable mould as principal constituent.Be the loss that prevents that fragmentation, wearing and tearing from bringing, and solid turns to the pelletizing shape.

Like this in the sludge modifying machine of Gou Chenging, the liquid that is modified of sending into top by the air riser pipe from top when move the bottom, by contacting, make useful soil bacteria propagation such as actinomycetes and move to the bottom simultaneously with the biological multiplying medium that is in 8 inside.

When rising to top, owing to be attended by air, thus keep the state of aerobism.

Repeat when mobile in the scope of aerobism and the anaerobic scope of general character, useful soil bacteria is in the liquid internal breeding that is modified, send into main body facility with some cycles, the distribution of the thalline in the main body facility is changed over the preferential states of useful soil bacteria such as actinomycetes from general bacterium, protozoon.

Main frame also is provided with the main body facility new facility sometimes simultaneously, also sometimes existing main body facility is appended setting.Appending under the situation of setting, appending concrete and flume and a lot of difficult problems are also arranged from spreading the condition of applying, therefore, as shown in Figure 2, steel basin be made as be provided with stirrer as and the structure of main frame with the horizontal stirring tank 11 of the scale of degree.

Main frame is packed under the situation of main body facility,, mixed solution extraction pump 12 is set, make the aeration tank mixed solution flow into main frames by pipeline 13 on the aeration tank inside or the top of main body facility as preceding narration.Liquid after the modification is timed by pipeline 10 and is sent to unboiled water groove and Flow-rate adjustment groove.Its purpose is narrated in front.

To aeration tank foldback mud, but make its part as shown in Figure 2 from the mud scale tank of main body facility, flow into the Flow-rate adjustment grooves by pipeline 14.This be for, be sent to the Flow-rate adjustment groove by the precipitating sludge that will be in general character anaerobism state, the Flow-rate adjustment groove is made as general character anaerobism state, the modification liquid that will send here from main frame and the mixed solution of unboiled water promote mixing effect under general character anaerobism environment.If it is not can access good mixing effect, then passable to the so big effect of the stirred pot expectation of preceding paragraph at this yet.
