Result On the whole, the collected sludge was a kind of organic fertilizer with high nutrient content, which contained rich organic matter (296.84g/kg on average), high nitrogen (48.33g/kg on average), medium phosphorus (18.94g/kg on average), low potassium (14.17g/kg on average). The pH value of the sludge was all in 5.95-7.73, being between subacidity and alkalescence, and application in the garden soil could not produce great influence on the acidity-alkalinity of soil.

结果］总体上所采集污泥是一种富含有机质（平均为296.84g/kg）、高氮（平均为48.33g/kg）、中磷（平均为18.94g/kg）、低钾（平均为14.17g/kg）的养分含量颇高的有机肥。pH值在5.95-7.73，处于微酸性和微碱性之间，在园林土壤中施用，不会对土壤的酸碱度造成大的影响。
