| 摘 要： | 测定了几种污泥的化学特性并将3种污泥施用在盆栽和田间试验的作物上。污水处理厂和啤酒污泥中氮、磷、钾及有机质的含量远高于机械厂和化工厂的污泥。施用污水处理厂和啤酒污泥能分别增加盆栽油菜和田间棉花的产量；在提高棉花经济产量上，啤酒污泥与化学肥料具有等效作用。因而，污水处理厂和啤酒污泥可作为土壤改良剂并有利于作物生长。化工厂污泥中镉、铜、铅、锌含量都高于其它污泥，盆栽棉花对化工厂污泥的瓜在也因土壤类型而异，因而将化工厂污泥应用于作物生产会带来重金属的污染。 |

| Abstract: | The chemical characteristics of several kinds of sludge were measured and three of them were applied to crops planted in pot and field experiment. The concentrations of organic matter, nitrogen, phosphorus and potassium in sludge from beer and wastewater plants is much higher than those from the mechanical and chemical factories. As a result, the yields of rapeseed grown in pot experiment and cotton grown in field trial have been raised by both sewage sludge and beer sludge, and the application of beer sludge is as effective as the standard fertilizer application in increasing the economic yield of cotton. Therefore, the sludge of beer and wastewater can be an amendment or conditioner of soil and do benefit to crop production. But the concentrations of cadmium, copper, lead and zinc in chemical factory sludge are all higher than the others, and the response of cotton to this sludge is dependent on soil type, so there will be more risks of heavy metal pollution in applying chemical industry sludge to crops. |
