About domestic sewage into the digesterBecause I am in contact with some related to sewage, biogas, biogas power generation project. The comprehensive utilization of sewage with manure and vegetation together into the biogas anaerobic fermentation is feasible, can achieve the sewage effluent standard, whether water can be reused, whether the relevant technology is mature. This time.
Sewage purification of biogas is a new type of structure decentralized sewage treatment, for in the near future to build urban sewage treatment plants, urban sewage pipe network or outside the unit, office buildings, residential, residential, hotels, schools and public toilet. The sewage water, including the kitchen cooking, bathing and washing water flushing toilet water
Standard performance of septic tank sewage purification of biogas digesters was significantly better than the commonly used, the country has built more than 7 thousand. The water quality investigation of sewage treated by BOD550mg/L, the value of fecal coliform bacteria >10-4, 0.565~1.074 /L the number of parasite eggs, fecal harmless standards have reached the national standard prescribed and outlet purification of biogas. No mosquitoes breed.
It has three characteristics: one is to flush the toilet water containing feces, is the source of the disease; two is the sewage concentration low, dry matter concentration was 1% among 3%, COD concentration is only 500~1000mg/L; three is the sewage biodegradability is good, COD/BOD is 0.0.6, suitable for biogas sewage. Purification of biogas according to the characteristics of sewage, the sewage anaerobic digestion, sedimentation and filtration techniques of thawing treatment device designed in one
