Ecological Remediation Method for Controlling Sulphur Pollution inBlack and Odorous Sludge of Rivers
20180002209 · 2018-01-04 ·

The Invention discloses an ecological remediation method for controlling sulphur pollution in black and odorous sludge of rivers. Firstly, the sludge from pollution layer of the rivers will be dredged and stacked on the banksides with slope protection built along the outer edge of the sludge storage site; then innocent pretreatment will be conducted for the sludge. Specific steps comprise solarization and ploughing, and mixed ameliorant of certain proportion will be added for modification between first solarization and intermittent ploughing. Then, large emergent aquatic plants will be planted on the stacked sludge after pretreatment. The technical method provided by the Invention may control the release of acid-volatile sulfide in the contaminated sludge on one hand and reduce concentration of volatile organic sulfide in the waters on the other hand. With simple technical process and strong operable technology, the Invention meets the current requirements for controlling sulphur pollution in black and odorous sludge of rivers in China and facilitates realizing the goal of long-term control of sulphur pollution in the deposit of the waters.
