Abstract

The invention relates to a contaminated bottom silt restoration composition, putting device and method. The composition is prepared from the following ingredients in percentage by mass: 5 to 20 percent of carbon fiber grass, 5 to 35 percent of zeolite, 10 to 35 percent of phosphor locking agents, 15 to 35 percent of charcoal and 5 to 35 percent of clean sand. The device can be a free moving putting device. When the bottom silt restoration composition, device and method are used for water body control and bottom silt restoration, nitrogen and phosphorus in the water body and the bottom silt canbe effectively removed; the bottom silt heavy metal, inorganic pollutants and microorganisms are adsorbed; the transparency of the water body is improved; the water body bottom silt is effectively restored. In addition, the device is used for performing composition putting; the device can be moved to any place specified by contaminated water bodies (rivers, lakes, reservoirs and the like) for water body control and bottom silt restoration; the device is simple and easy; the operation is convenient; the efficiency is high.

Description

technical field [0001] The invention relates to a contaminated bottom mud restoration composition, a dispensing device and a method, and belongs to the field of water environment protection. Background technique [0002] Water is the source of life, the key to production, and the foundation of ecology. However, with the rapid development of my country's economy and the rapid advancement of urbanization, the problem of environmental pollution is becoming more and more serious, among which the pollution of water environment is particularly prominent. The direct discharge of agricultural non-point source pollution, industrial wastewater and domestic sewage into natural water bodies causes water bodies such as rivers, lakes and reservoirs to be polluted and damaged to varying degrees, resulting in eutrophication of water bodies, heavy metal pollution, and black and odorous water bodies etc. have brought severe challenges to the safety and stability of the water ecosystem, and s...
