硫铵法洗毛污水污泥农业利用研究

通过小麦盆栽试验，研究了毛纺企业排放的洗毛污水、污泥对农作物及土壤的影响。结果表明，适宜用量洗毛污水、污泥对盆栽小麦有一定的增产效果，并使小麦营养品质有显著提高。施用洗毛污水、污泥后，盆栽土壤没有明显积累有害盐分，土壤理化性状基本没有变化。洗毛污水、污泥可以作为农业生产新的水肥资源加以开发利用。

Utilization of Sludge and Sewage from Washing Wool with Ammonium Sulfate on Agriculture

A set of pot tests was done to show the possibility of utilization of sludge and sewage from washing wool with ammonium sulfate on agriculture. The results showed that appropriate amounts of both sludge and sewage could enhance quality and significantly improve quantity of wheat. The application of sludge and sewage had neither accumulation of salts, nor effects on physical and chemical properties of the soil tested. It may be concluded that it is likely to utilize the sewage and sludge both as water and nutrients, respectively, on agriculture.
