The connecting tube 9 being connect with second-level settling pond 2, while 9 water outlet of connecting tube extends in second-level settling pond 2 and passes through secondary filtration
Net 8, then the waste water entered in first stage precipitation tank 1 from inlet tube 5 filters and fall to the one of its bottom by primary filter 7
In grade sedimentation basin 1, and pass through the liquid of filtering from 9 overflow of connecting tube to (the namely second level in the second-level settling pond 2 of lower
In the second-level settling pond 2 of 8 lower section of filter screen), it is then influxed on liquid in the second-level settling pond 2 above secondary filter 8, so that
Secondary filter 8 carries out secondary filter to liquid, and wherein 8 aperture of secondary filter is less than 7 aperture of primary filter, then also
It is to say that secondary filter 8 can further filter out the impurity being mingled in liquid.
Medium storage bin 12 is wherein aloft installed, and 12 bottom of medium storage bin is equipped with and connect with connecting tube 9
Medium circulation tube 13, and control valve 14 is provided in medium circulation tube 13, by opening controlling valve 14 by medium storage bin 12
Interior chemical reaction liquid is imported in connecting tube 9 and is flowed into second-level settling pond 2 together with waste water, and will by rabbling mechanism 6
Waste water is mixed with medium, so that the two mixing is more thorough, as shown in Figure 1,602 bottom end of shaft and stirring blade 603 are respectively positioned on
In the second-level settling pond 2 of 8 top of secondary filter, to prevent the shaft 602 of rotation and stirring blade 603 from can touch second level
Filter screen 8.
And it is welded with the L-type main water outlet pipe 10 of back-off setting in 2 top side wall of second-level settling pond, and works as second-level settling pond
When liquid level in 2 is more than main water outlet pipe 10, the liquid level that transfinites can drain into trench or recycle-water through the water pipe connecting with main water outlet pipe 10
It is spare in pond, when first stage precipitation tank 1 is unable to when supplying water to second-level settling pond 2 of duration, then the liquid level in second-level settling pond 2
Then can duration decline, cause the liquid in second-level settling pond 2 by filtering to drop to main water outlet pipe 10 and second-level settling pond 2
When the lower section of junction, liquid cannot smoothly be flowed into main water outlet pipe 10, so in the present embodiment above secondary filter 8
2 side wall of second-level settling pond on be welded with the exit branch 11 connecting with main water outlet pipe 10, control is installed on the exit branch 11
Valve 14 processed will be located at 8 top of secondary filter, main water outlet by exit branch 11 then when in use opening control valve 14
The liquid in second-level settling pond 2 below pipe 10 and 2 junction of second-level settling pond imports in main water outlet pipe 10, thus by second level mistake
The liquid of 8 top of strainer in exit branch 11 and main water outlet pipe 10 by draining.
As a preferred embodiment, control valve 14 is installed in connecting tube 9, which is located at medium circulation tube 13
In connecting tube 9 between first stage precipitation tank 1, by opening and closing close the control valve 14 can control the liquid in first stage precipitation tank 1 into
Enter in connecting tube 9 and flows into second-level settling pond 2.
It is welded with sewage pipe 15 in first stage precipitation tank 1 and 2 bottom of second-level settling pond simultaneously, then in first stage precipitation tank 1
Interior liquid level lower than after below connecting tube 9 and 1 junction of first stage precipitation tank, in second-level settling pond 2 liquid level lower than after exit branch 11,
Wherein the control valve 14 in medium circulation tube 13 is closed, and is not continued in first stage precipitation tank 1 after water filling by inlet tube 5,
Since first stage precipitation tank 1 and 2 bottom of second-level settling pond can deposit one layer of thicker sediment, and open first stage precipitation tank 1 and two
After the sewage pipe 15 of 2 bottom of grade sedimentation basin, sediment is also not susceptible to flow out from sewage pipe 15, so heavy in level-one in the present embodiment
Shallow lake pond 1 and 2 bottom of second-level settling pond are welded with backwash mechanism 3, and backwash mechanism 3 includes water inlet pipe 301, passes through pipeline
The backwash pump 302 being connect with water inlet pipe 301 and the non-return valve 303 being mounted on water inlet pipe 301, wherein water inlet pipe 301 with
Corresponding first stage precipitation tank 1 and the welding of 2 bottom wall of second-level settling pond, then opening sewage pipe 15 at work for first stage precipitation tank 1
And when the discharge of 2 bottom liquid of second-level settling pond, if sediment blocks 15 feed end of sewage pipe, then it can open backwash pump
302 extract liquid by pipeline and import in first stage precipitation tank 1 or second-level settling pond 2 through water inlet pipe 301, so that high pressure is anti-
Flushing water rushes the sediment of 2 bottom of first stage precipitation tank 1 or second-level settling pond, mixes it with liquid and by 15 row of sewage pipe
Out, while in order to prevent the liquid of 2 bottom of first stage precipitation tank 1 or second-level settling pond can flow backward to backwash pump 302, then
Non-return valve 303 is installed on water inlet pipe 301,2 bottom of first stage precipitation tank 1 or second-level settling pond is prevented by non-return valve 303
Liquid can flow backward to backwash pump 302, play good effect to the safety for promoting backwash pump 302.
It is welded with the discharge nozzle 16 through 2 bottom wall of second-level settling pond in 8 middle of secondary filter in the present embodiment, is being gone out
The clearance seal of the two is prevented into 8 bottom of secondary filter by the way of welding between 2 bottom wall of expects pipe 16 and second-level settling pond
Liquid in second-level settling pond 2 is flowed out from gap between the two, after liquid level is lower than secondary filter 8 in second-level settling pond 2,
Discharge nozzle 16 can be opened for the impurity of 8 top of secondary filter to be discharged.
The application method of the utility model: liquid is imported in first stage precipitation tank 1 from inlet tube 5, liquid is through by-pass filtration
Net 7 is filtered and is fallen in first stage precipitation tank 1 below, and then liquid flows into the two of 8 lower section of secondary filter through connecting tube 9
