摘要
Abstract
Recently, with the continuous development of sewage treatment plants, the total output of municipal sludge as a by-product of sewage treatment plant is also increasing� When the sludge is used for soil improvement, the content of organic matter has an important role; however, there is still no standard test method for sludge� Based on soil organic matter determination method on the determination of the content of organic matter, we use the potassium dichromate volumetric method for the determination of organic matter content in city sludge, which is stable, simple and reliable� And finally we got a recovery rate of 90-110% in real samples, which can be used as a standard method for the determination of organic matter content of sludge in the city.关键词
