Anaerobic jar matches somebody with somebody water circulating pump model 150WL210-7-7.5, totally 2.Circulating pump performance：Flow 210m3/h, lift 7m, power 7.5kw.
Sedimentation basin and water sealed tank, the sedimentation basin and water sealed tank are located at the downstream of IC anaerobic reactors side by side；The precipitation Pond carries out sludge settling to anaerobic effluent, and the sludge biogas residue of generation is sent to agricultural；The water sealed tank to the biogas that anaerobism produces into Row water seal is handled；
Biogas basin, the biogas basin are located at the downstream of water sealed tank, and the biogas basin collects storage biogas；
Aerobic zone is mixed, the mixing aerobic zone is located at the downstream of sedimentation basin, it carries out the supernatant produced after precipitation Aerobic compost processing；
Sand filter, the sand filter are located at the downstream of mixing aerobic zone, it removes the supernatant Jing Guo Aerobic Process for Treatment Sand processing；
Ecological pool, the ecological pool are located at the downstream of sand filter, it can be to the animal and plant growth in it, and the water of discharge can be straight For sewage treatment plant of city.
Based on the above technical solutions, the present invention can also be improved as follows.
Further, the water of ecological pool discharge can also direct-furnish sludge drying pond, the sludge drying pond is located at ecological pool Downstream, its by ecological pool discharge water precipitated, precipitated liquid send to mixing aerobic zone, precipitation sludge send to agricultural.
Compared with prior art, the beneficial effects of the invention are as follows：It is equipment connection and reasonable arrangement, compact, both can be by vegetable protein Waste water carries out conventional treatment, and the product after the processing that can be is efficiently used, and is avoided wasting, is saved the energy；IC anaerobism Reactor has larger ratio of height to diameter and high organic loading rate, compared to other type anaerobic reactors have volume it is small, processing Efficient, the stable, outstanding advantages such as sludge yield is few, floor space is small, operating cost is low.
