高效生活污水净化槽的研究

Study on Compact Domestic Sewage Purificator

开发研究了一种新型的无污泥排放、无需专人管理的高效生活污水（含粪便）净化槽．该装置采用了厌氧－好氧流程来处理高浓度生活污水，造价略高于化粪池．试验表明：装置在污水停留时间为１８ｈ时（略低于传统化粪池），出水ＣＯＤ＜１２ｍｇ／Ｌ，ＣＯＤ去除率＞９０％，ＢＯＤ５去除率＞９５％，出水水质达到国家污水排放标准．从我国现有国情来看，这是一种值得推广的分散型高浓度生活污水净化装置．

A kind of compact domestic sewage purificator is introduced in this paper, which can treat high strength domestic sewage (with evcrement and wrine) with non discharging of sludge, low power cost and operator free. Ananerobic, aerobic treating method are adopted in this purificator. The result of experiment showed, when its retaining period is a little less than traditional septic tank, its total removing rate of COD and SS is above 90%, the effluent can meet the national standard. In view of the practical condition of our conutry, the purificator is a prospective equipment of treating domestic sewage.
