Method for improving black and odorous water body through coverage of modified zeolite for environmental dredging

The invention discloses a method for improving a black and odorous water body through coverage of modified zeolite for environmental dredging. The method comprises the steps of combing environmental dredging technology and modified zeolite coverage technology to restore contaminated sediment, improving the quality of the water body through simulation tests aiming at the contaminated sediment of the black and odorous water body and the environmental dredging technology and modified zeolite coverage technology, and obtaining optimum operation parameters. The method has the beneficial effects that a technical support is provided for thoroughly improving the water quality of contaminated rivers, and a theoretical direction is further provided for water body restoration engineering applicationof the contaminated rivers; the existence significance of microorganism during the water body restoration is discussed through investigation of the variation of the microorganism in the improvement ofthe quality of the water body, so as to analyze and judge the stability and restorability of the water body after restoration of the water body, and a scientific basis can be provided for the selection of schemes of water body restoration technology; the risk caused by artificial perturbation to the water body due to the restoration schemes is analyzed by taking sediment microorganism species andactivity as evaluation indexes, and a scientific basis is provided for the final implementation of the schemes of the water body restoration technology.
