Operation principle of the present invention is as follows:
1) breeding wastewater introduces collecting pit by sewage ditch, be stirred in collecting pit it is broken, the step in pig house or In person's cowshed when stool and urine, cleaning cleaning is carried out to pig house or cowshed ground by cleaning device, the sewage after cleaning Collecting pit is introduced into by sewage ditch, by stirring breaker is advantageous to that pig dung or cow dung are stirred and crushed, Be easy to make pig dung or cow dung be mixed with water, and be sucked into pretreatment box and handled, should avoid pig dung or Either ox urine is deposited in pig house or the working of cowshed ground or rested on for a long time in collecting pit for cow dung, pig urcine, ensures The clean and cleaning of collecting pit, avoids collecting pit from peculiar smell occur.
The index of waste water in collecting pit such as following table:
Index CODcr BOD5 Ammonia nitrogen ss Coliform group count
Numerical value (mg/L) 15000-25000 4000-7000 1000-1500 5000-7000 2.4x100000000
2) waste water of collecting pit is pumped into by pretreatment box by drawing liquid pump I, after adding a certain amount of flocculant and stirring 1h, so After carry out separation of solid and liquid, the step is mainly by will add flocculant, to pig dung or cow dung, in pig urcine or ox urine not The particle for being dissolved in water carries out precipitation flocculation, then separates pig dung or cow dung by separation of solid and liquid separator, pig urcine or In ox urine, wherein in high-speed agitating process, polyacrylamide flocculant is sufficiently mixed with sludge;Subsequent stirring at low speed process In, the particle in flocculant absorption sludge, form larger floc sedimentation;If high-speed stirred overlong time or excessive velocities, can by having Established floc sedimentation can be caused broken;, whereas if mixing time is too short or speed is not fast enough;Flocculant can not fill with sludge Point mixing, the little particle caused in sludge is adsorbed incomplete, can not only go to denitrogenate, phosphorus and a part of antibiotic (such as sulphur Amine, macrolides and Tetracyclines), and a part of heavy metal (copper, arsenic, zinc, lead and nickel etc.);Reach what purification de-tasted Effect.
In the index such as following table of the waste water after pretreatment and separation of solid and liquid:
Index CODcr BOD5 Ammonia nitrogen ss Coliform group count
Numerical value (mg/L) 8000-15000 2000-4000 100-150 300-400 20000-40000
3) liquid after separation of solid and liquid delivers to simultaneous oxygen case by pumping;Start the underwater stirrer being arranged in simultaneous oxygen case, make Sewage is sufficiently stirred hydrolysis, and then overflow enters aeration case, and the organic matter in waste water is filled being aerated in case in the presence of microorganism Point nitration reaction, during nitration reaction pH value control flowed back into 7.5, nitrification liquid from aeration case and the water of oxygen case be by And oxygen case direct current enters 5-10 times of aeration case water, the water outlet for being aerated case is pumped to film processing system through drawing liquid pump I, the step So that it is removed by pollutants such as the most CODCr and BOD5 after separation of solid and liquid, in addition further to ammonia nitrogen, total nitrogen With the removal of total phosphorus, the burden of the contaminated wastewater of livestock and poultry cultivation is significantly reduced;
Water quality index such as following table after simultaneous oxygen and Air Exposure:
Index CODcr BOD5 Ammonia nitrogen ss Coliform group count
Numerical value (mg/L) 600-800 200-300 100-120 200-400 15000-25000
4) duckweed pond is entered after biofilm filtration into the clear water of film processing system, the step is by adding biology system Agent, using bio membrane treatment, separation of solid and liquid is efficiently carried out, its separating effect is much better than traditional sedimentation basin, water outlet water Matter is good, goes out aqueous suspension and turbidity close to zero, can direct reuse, realize sewage recycling;The wherein efficient retention of film Effect, makes microorganism be completely trapped in bioreactor, realizes reactor hydraulic detention time (HRT) and sludge age (SRT) Be kept completely separate, operation control is flexibly stable, because the aeration tank that traditional wastewater is handled and second pond are combined into one by MBR, and Whole process facilities of tertiary treatment are instead of, therefore floor space can be greatly decreased, save construction investment;Beneficial to nitrobacteria Retention and breeding, system nitrification efficiency is high.Can also there are deamination and phosphorus removal functional by the change of the method for operation;Because sludge age can With very long, so as to greatly improve the degradation efficiency of hardly degraded organic substance;Other reactor is born in high volumetric loading, low sludge Run under lotus, long sludge age, excess sludge production is extremely low, due to sludge age can endless, zero sludge discharge can be realized in theory;
Water quality index such as following table after biological film process:
Index CODcr BOD5 Ammonia nitrogen ss Coliform group count
Numerical value (mg/L) 350-400 100-150 60-80 100-150 8000-10000
Further, entered in the preferable step 2) by the solid of separation of solid and liquid in methane-generating pit and carry out fermentation process, Caused fire damp is automatically drained out using positive pressure biogas structural tube road in methane-generating pit.
Further, aeration bottom portion is provided with air aeration equipment, the aeration side of use in the preferable step 3) Formula has boring aeration, jet-flow aeration or micro-pore aeration.
Further, adding appropriate NaOH in the preferable step 3) during nitration reaction makes pH value control 7.5.
Further, formed during the preferable methane-generating pit is interior after precipitating sludge and organic matter and the biofilm filtration The fertile heap for being piled into high 1.5-2.0m is mixed evenly according to mass ratio with rape slag, bean dregs for sludge, carries out at fermentation maturity Reason, then fertilizer is obtained after granulation.
Finally illustrate, preferred embodiment above is merely illustrative of the technical solution of the present invention and unrestricted, although logical Cross above preferred embodiment the present invention is described in detail, it is to be understood by those skilled in the art that can be Various changes are made to it in form and in details, without departing from claims of the present invention limited range.
