摘　　要：使用大同地区粉煤灰及污水处理厂的二次污泥,采用"物理生物联合法",通过实验,对生活污水化学需氧量的降解过程进行了优化处理。研究了粉煤灰和污泥在不同实验条件下,对污水中化学需氧量的去除效果。研究结果表明:150 mL的生活污水,经粉煤灰6 g、污泥8 g、静置时间15 min的处理过程,其COD去除率可达到62%。A test was done on the optimized degradation of the COD of the domestic wastewater by way of the joint physical/biological method based on the boiler fly ash from the Datong area and the secondary sludge from the wastewater treatment plant. The different wastewater COD removal effect of the fly ash and the secondary sludge under different test conditions was studied and the result indicated that the COD removal rate of 150 mL domestic sewage was up to 62% in the presence of 6 g of flay ash and 8 g of sludge （holding time being 15 min）. It proved that the use of fly ash combined with secondary sludge was effective for treating municipal wastewater.
