Lake, shallow lake and fishpond desilting sediment and tail water treatment process

Abstract

The invention discloses a lake, shallow lake and fishpond desilting sediment and tail water treatment process, relates to the technical field of water treatment by adopting three treatment processes of a desilting ship geotextile tube dehydration method, a natural airing dehydration method and a high-pressure mud pump plate-frame filter pressing dehydration method. According to the lake, shallow lake and fishpond desilting sediment and tail water treatment process, aiming at different-area water areas, different treatment processes need to be adopted for treating sediment of lakes, shallow lakes, fishponds and the like with different water quantities, therefore, an economic, efficient and reasonable treatment effect is achieved, the energy consumption and the resource energy loss are reduced, sediment pollutants are effectively removed, release of muddy water pollutants is reduced, water quality is improved, a water environment bearing capacity is greatly improved, prerequisite guarantee is provided for habitat recovery, ecological environment health recovery is promoted, and endogenous treatment on the settled area is carried out from a fundamental starting point, so that the endogenous problem of the environment is solved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a process for treating lakes, lakes and fish ponds for dredging sediment and tail water. Background technique [0002] Because there are many upstream villages in rivers, lakes, and lakes, rural domestic sewage is directly discharged into the river, and the pollution load is relatively large. Distributed livestock and poultry breeding domestic sewage directly enters the river, and domestic garbage is randomly piled up; embankment vegetation is scarce, and water and soil are lost; undertaking upstream cities Sewage discharge, the water body is in a polluted state; the surrounding lake has a large planting area, agricultural pollution directly enters the river, and vegetation is scarce, soil erosion and other comprehensive factors. Threats to lakes / deposits have increased, water quality has deteriorated, and the environment has changed, increasing the possibility of ecologi...

Problems solved by technology

[0002] Because there are many upstream villages in rivers, lakes, and lakes, rural domestic sewage is directly discharged into the river, and the pollution load is relatively large. Distributed livestock and poultry breeding domestic sewage directly enters the river, and domestic garbage is randomly piled up; embankment vegetation is scarce, and water and soil are lost; undertaking upstream cities Sewage discharge, the water body is in a polluted state; the surrounding lake has a large planting area, agricultural pollution directly enters the river, and vegetation is scarce, soil erosion and other comprehensive factors. Threats to lakes / deposits have increased, water quality has deteriorated, and the environment has changed, increasing the possibility of ecological damage, and many pollutants have been deposited in the bottom mud, which not only endangers the sustainable reproduction of aquatic animals and plants in lakes / deposits, but also Affecting the production and life of hundreds of thousands of people in Dian District
