The research for combined treatment of small eco-equipment to decentralized sewage

In order to promote regional sewage pipe network and sewage incomplete dispersion area sewage treatment, biological purification and filtration combined with underground, a small modular ecological design of sewage treatment facilities. In the winter day the water content of 100L/d under the conditions studied the effects of their purification. The results showed that, when COD, NH4+-N, TP influent concentration at 113.68 ~ 245.76 mg/L, 4.86 ~ 25.50 mg/L, 1.89 ~ 12.10 mg/L range of changes, COD, NH4+-N, TP to in addition to rate increases as the concentration of larger, the corresponding removal rate was 85.85%, 59.71%, 63.5%, reflecting the strong resistance to impact load.
