In-situ rapid treatment material for black and odorous water body and bottom sludge in cities and towns

Abstract

The invention belongs to the technical field of water environment treatment and relates to a rapid treatment material for treating and purifying wastewater and bottom sludge in the wastewater. An in-situ rapid treatment material for a black and odorous water body and the bottom sludge in cities and towns is prepared from the following components in parts by mass: 2 to 15 parts of thiobacillus denitrificans, 3 to 30 parts of EM bacteria, 0.5 to 15 parts of nitrifying bacteria, 1 to 15 parts of activated clay, 1 to 15 parts of zeolite, 1 to 20 parts of calcium nitrate, 0.5 to 5 parts of sodium carbonate, 5 to 40 parts of aluminum sulfate and 1 to 10 parts of polyacrylamide. According to the in-situ rapid treatment material for the black and odorous water body and the bottom sludge in citiesand towns, disclosed by the invention, by uniformly mixing a repairing material with the black and odorous water body and the bottom sludge in situ, nitrogen, phosphorus, sulfur, organic matters and the like in the water body and the bottom sludge can be effectively removed and the odor is eliminated, so that the effect of controlling endogenous pollution of a river channel is realized. The rapidtreatment material disclosed by the invention has the advantages of convenience in operation, small engineering quantity, time saving and cost saving, no secondary pollution and obvious effect; and the self-purification ability of the water body is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of water environment treatment, and relates to a material for rapid treatment of sewage treatment and purification and sediment. Background technique [0002] In recent years, many black and odorous water river improvement projects have been carried out in various places in my country. With the implementation of river improvement projects such as sewage interception and dredging, the external source pollution of urban rivers has been greatly reduced. After the exogenous pollutants are effectively controlled, the endogenous nutrients in the sediment become the main source of water pollution. When the external pollution sources are improved and the water quality of the overlying water body improves, the pollutants in the sediment will be released to the overlying water body, affecting the water quality of the overlying water body. Therefore, the polluted sediment, as the internal pollution source of the river...
