摘　　要：研究了不同混凝剂硫酸铝、膨润土、壳聚糖、聚丙烯酰胺对养猪场污水COD_G去除率、原水色度的影响;通过复配制得两种经济型复合混凝剂,使COD_G的去除率分别达到38.8%和20.0%,污水颜色变浅,动、植物可在其中生长,为后续生物处理创造了条件。The effects of different flocculant aluminum sulfate （Al2（SO4）3）, Alta-mud, chitosan, PAM on CODCr removal rate and color reduction were investigated. Through combining with several compounds, two kinds of economical composite flocculant were obtained, and the CODCr removal rate of wastewater was 38.8% 、20.0% respectively, and the color of wastewater became light. Some animals and plants can live in treated water. It provided possible pretreatment way for post biological treatment.
