Problems solved by technology

However, if the process of dredging and silt treatment in different places is used for water control first, it will be difficult to transport, take a long time, require a large investment, and use a large area of ​​land. In addition, slight omissions in the construction process will lead to the pollution of pollutants in the sediment. The risk of secondary pollution caused by air, soil and groundwater

Abstract

The invention discloses a black and odorous water treatment agent and an application thereof. The treatment agent is prepared from components in parts by mass as follows: 330-500 parts of a flocculating agent, 110-174 parts of an adsorbent, 170-225 parts of a settling agent, 140-190 parts of a water softener, 160-210 parts of an oxidizing agent, 140-165 parts of a purifier, 170-240 parts of an ionexchanger, 90-160 parts of a chelating agent, 8-30 parts of bacillus powder, 5-30 parts of desulphurization bacterium powder and 8000 parts of zeolite particles. The invention provides the application of the black and odorous water treatment agent to treatment and repair of black and odorous water. With the adoption of the treatment agent, quality of the black and odorous water can be changed ina short time and enabled to reach the surface water class-VI standard. When the treatment agent is applied to in-situ treatment of the black and odorous water, the investment is reduced by 60% or morecompared with that of an ex-situ treatment technology for bottom mud, secondary pollution risk of the bottom mud for atmosphere, soil and underground is greatly reduced, and the restoration time is short.

Description

technical field [0001] The invention belongs to the technical field of water environment treatment and restoration, and in particular relates to a treatment agent for black and odorous water and its application. Background technique [0002] With the development of the city, environmental pollution continues to plague the lives of residents. The development of human beings depends on water, but the water we depend on for survival has changed, becoming black and smelly. Black and odorous water body is an important manifestation of current water body pollution, that is, a large amount of nutrients such as nitrogen and phosphorus in the water body accumulate, the water body is seriously hypoxic, the sediment has a serious history of sedimentation, and the water body has poor transparency. [0003] In recent years, the implementation of exogenous emission reduction work in some rivers with serious black and odorous water has effectively controlled exogenous pollutants. The mut...
