摘要
本文探讨不同有机负荷、不同ｐＨ值和不同性质的污水在厌氧塘中的降解情况．试验表明：厌氧塘的去污效果受有机负荷、污水性质和污水ｐＨ值的影响；在２５℃，水力停留时间８天条件下，厌氧塘污水ＣＯＤ最高去除效率可达７０％．本文还分析了厌氧塘的生物降解机理和动力学规律．
The efficiency of treating wastewater is studied in anaerobic pond, by different organic load .pH .anddifferent category wastewater,at 25℃,7 days illumination time. The experimental results show: (1 ) different wastewater decided the diffrent purificating efficiency,high protein wastewater are fixed to anaerobic pond treatmert.(2) organic load and pH of wastewater affect the purifioating efficiency. The highorganic load is the better treatment efficiency,in the range of assimilative capacity. The anaerobic pondtreating wastewater need neutral pH. The optimal COD removal rate reach 70%.(3 ) The mechanism oftreating wastewater in anaerobic pond are discussed.
