(1), the sewage that produces of pig house removes after suspended substance through grid canal and enters the dirty pond of collection, and sewage pumps into the first equalizing tank after the dirty pond of collection stops 1 ~ 3 hour;
(2), by after pig manure fragmentation send into the first equalizing tank, pig manure and sewage are uniformly mixed;
(3), the raw material mixed is pumped into CSTR reactor by cutting pump;
(4), the biogas residue and biogas liquid gravity flow out of CSTR reactor enters Secondary Fermentation pond and ferments further;
(5) biogas residue and biogas liquid, after fermentation pumps into concentration basin, after concentrated through solid-liquid separating machine by natural pond slag and natural pond liquid separately;
(6), by natural pond slag make fertilizer through stirring, granulation, oven dry, secondary drying, screening, cooling, regrading, natural pond liquid is made natural pond liquid fertilizer after biochemical treatment tank process.
Preferably, in step (1), sewage stops 2 hours in the dirty pond of collection.
Preferably, in step (2), the TS concentration after pig manure and sewage being uniformly mixed controls to be 8% ~ 13%.
Preferably, in step (3), before raw material being pumped into CSTR reactor, the second equalizing tank is again pumped into, further mixing and stirring.
The invention has the beneficial effects as follows: efficiently solve the pollution of Piggery manure waste water to environment, improve the ecotope of surrounding, decrease the generation of disease, aquaculture industrial chain is elongated; Decrease the usage quantity of chemical fertilizer and agricultural chemicals, alleviate the soil pollution that chemical fertilizer and agricultural chemicals bring; Structure is simple, efficiency is high, easy to operate, cost-saving and space, is beneficial to the Sustainable development of economic society, has driven the development of related industries, has facilitated the recycle of resource, be beneficial to the adjustment of China's energy structure.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Accompanying drawing 1 is structured flowchart of the present invention;
Accompanying drawing 2 is the process flow sheet that natural pond of the present invention slag makes fertilizer;
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises pig house, grid canal is connected with bottom pig house, grid canal is connected with the dirty pond of collection, collect dirty pond and be connected with the first equalizing tank, first equalizing tank is connected with the second equalizing tank, and the second equalizing tank is connected with CSTR reactor, and CSTR reactor is connected with Secondary Fermentation pond, Secondary Fermentation pond is connected with concentration basin, and concentration basin is connected with solid-liquid separating machine.First equalizing tank is connected with pulverizer.Collect between dirty pond and the first equalizing tank and between the first equalizing tank and the second equalizing tank and be provided with lift pump.Cutting pump is provided with between second equalizing tank and CSTR reactor.
Pig dung and urine of the present invention production biogas residue and biogas liquid is adopted to make the method for chemical fertilizer, sewage by irrigation canals and ditches by place flow automatically enter treatment facility before, waste water is first through grid canal, after removing levitated object large in waste water by grid canal, waste water is from flowing into the dirty pond of collection, and the difference of filtering as required needs grid canal to be divided into fine fack and coarse rack.Due to flushing waste water discharge periodicity, water yield change greatly, needs waste water to be introduced the dirty pond of collection and stays for some time, be generally 1 ~ 3 hour, preferably 2 hours, ensure the normal operation of follow-up structures.Then the first equalizing tank is pumped into, the pig manure of pulverizing is sent into the first equalizing tank, pig manure and sewage enter the first equalizing tank to be needed to dilute conciliation further, establishes whipping appts bottom the first equalizing tank simultaneously, make it all to measure homogeneous, ensure the normal operation of follow-up structures.The second equalizing tank is again pumped into after being uniformly mixed, after making its TS concentration reach 8% ~ 13%, CSTR reactor is pumped into by cutting pump, raw material is anaerobically fermenting under the anerobe effect of CSTR reactor, biogas residue and biogas liquid gravity flow after anaerobically fermenting enters Secondary Fermentation pond and ferments further, biogas residue and biogas liquid after fermentation pumps into concentration basin, through solid-liquid separation, natural pond slag, part natural pond liquid are used for doing fertilizer through stirring, granulation, oven dry, secondary drying, screening, cooling, regrading, all the other natural pond liquid after biochemical treatment tank process is up to standard, as natural pond liquid fertilizer.
