【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。更多还原

【Abstract】 The effects of different flocculant aluminum sulfate（Al₂（SO₄）₃）,Alta-mud,chitosan,PAM on COD_G removal rate and color reduction were investigated.Through combining with several compounds,two kinds of economical composite flocculant were obtained,and the COD_G 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.更多还原
