摘　　要：在单独净化槽的基础上针对农村现有的自来水化工程相配的化粪池,研发多户联用的多功能高效新型净化槽,调查了生物滤床对污水净化作用,测定了各区BOD5、氨氮和浊度的变化情况,讨论了各区生物滤床对出水水质的影响。结果表明:当处理能力为单独净化槽4倍情况下,各区加入滤床后出水的BOD5、氨氮和浊度分别为3 mg/L、10.5 mg/L和5NTU,水质指标均可达到国家一级排放标准,大大减少了净化槽的投资费用。To point against the septic tank that is matched rural water supply engineering,a new integrated and highly effective purifying-tank was developed on the basis of individual one.The purification of bio-filter bed was investigated and its influence on effluent quality was discussed by determining the changes of BOD5,NH3-N and turbidity in all zones.The processing capacity of new integrated purifying-tank was 4 times as that of the individual one,and the experimental results showed that the average effluent value of BOD5,NH3-N and turbidity was 3 mg/L,10.5 mg/L and 5NTU,respectively,as the bio-filter beds are added in the anaerobic zone and two aerobic zones successively,which is better than the national primary standard and reduced the costs greatly.
