新型一体化装置处理生活污水的试验研究

Investigation on Living Sewage Treatment with a New Type Integrated Device

采用新型一体化装置处理生活污水,在水力停留时间3 h,溶解氧2 mg·L-1,每天排泥2 L,污泥体积指数为60时,对生活污水中CODCr和氨氮去除率均达到90%以上,出水达到国家污水排放一级标准.该反应装置具有设备简单,操作方便,占地面积小等优点,具有广阔的应用前途.

The new type of integrated instrument used to treat living sewage can wipe 90% COD_(Cr) and NH_4-N out as the reaction condition of hydraulic retention is 3 hours, mass of sludge lost is 2 L/d , DO is (2.0 mg/L) and SVI is 60.As a result,its effluent can reach the national first class standard of sewage discharge.The instrument would expect to be widely used for its advantages of small floor space with simple equipment and it is easy to be operate.
