Floating platform for sediment elution

Abstract

The invention belongs to the technical field of environmental protection equipment, and in particular relates to a floating platform for washing out sediment, including a floating platform, a mud disturbing device, a mud-water separation device and a power device provided on the floating platform. The invention adopts a hydraulic control system to control the lifting and washing frequency of the mud disturbing device, which is well adapted to the topography, depth and environment of various water areas, and the muddy water after washing can be bagged and transported through the sludge dewatering machine after settling , to prevent secondary pollution caused by transportation and storage, and the self-provided fuel generator can meet the requirements of field construction operations. At the same time, the invention can disassemble the products for transportation separately, and assemble them on site for convenient transportation, which effectively improves the work efficiency and effectiveness.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a floating platform for washing out sediment. Background technique [0002] With the development of the economy, the degree of eutrophication of natural lakes, rivers, landscape water and other water bodies has been increasing and the water quality has deteriorated in the past 20 years. Due to the accumulation of water body all year round, a large amount of sediment is accumulated, and the sediment contains a large amount of pollutants, including nutrients such as N and P and heavy metal pollutants that cause eutrophication of the water body. These harmful substances will destroy the aquatic ecological environment and seriously affect human health. [0003] At present, the treatment methods for sediment are mainly divided into three categories: one is physical restoration technology, which mainly uses engineering technology to eliminate sed...

Problems solved by technology

These harmful substances will destroy the aquatic ecological environment and seriously affect human health.

[0003] At present, the treatment methods for sediment are mainly divided into three categories: one is physical restoration technology, which mainly uses engineering technology to eliminate sediment pollution, mainly including dredging, water diversion, and sand filling and covering; the other is through aeration, adding aluminum salt, Coagulants such as iron salts inhibit the release of endogenous phosphorus, and the aeration method has the disadvantage of a small and uneven oxygenation range, and this method can only improve the black and odor phenomenon of the water body. In order to inhibit the eutrophication of the water body and achieve clear water quality , it is often necessary to add chemical agents to inhibit the release of endogenous phosphorus, thereby polluting the water body and affecting aquatic ecology; the third is bioremediation technology, which refers to the use of organisms to degrade water pollutants, eliminate sediment pollution, and reduce endogenous phosphorus loads , however, the adoption of bioremediation technology is slow and has obvious hysteresis, and most of them are still in the experimental stage, which is not suitable for large-scale promotion

[0004] Regarding the method of dredging the river course in the physical restoration technology, there are the following deficiencies in the sediment washing platform in the prior art: (1) can not operate in the field without power supply; (2) the working depth of the sediment treatment water area is not enough; (3) It is inconvenient to stack and transport the cleaned up mud; (4) It is inconvenient to disassemble, install and transport the working platform
