Multifunctional bottom mud eluting-disturbing device

Abstract

The invention discloses a multifunctional bottom mud eluting-disturbing device, namely a multifunctional eluting-disturbing head, which is arranged at the front end of a bottom mud eluting ship and has multiple disturbing modes. The device comprises a jet device, an aeration device and an electric mechanical disturbing device, which are independently arranged in an elution box and are connected with a control box. The aeration device is arranged in the elution box and is used for carrying out aeration on riverway bottom mud and filling oxygen into riverway bottom mud, releasing pollutants on the surface layer of the bottom mud into an elution chamber, and pumping the bottom mud to the shore. The jet device ejects high pressure water flow, which is formed by making water pumped by a high pressure pump go through a jet hole, on riverway bottom mud so as to disperse the pollutant layer on the bottom mud, the pollutants are released and delivered to the shore. The mechanical disturbance isthat the river bottom mud is disturbed, rotated and scattered through the rotation of a disturbing head, so that pollutants are released. The adaptability of the bottom mud eluting ship to differentkinds of riverway bottom mud is improved, the bottom mud eluting ship can better adapt to the field environment, and the working efficiency and the treatment capacity of the bottom mud eluting ship are improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a multifunctional sediment washing and disturbing device. Background technique [0002] Pollutants such as N and P brought by industrial wastewater, domestic sewage, agricultural fertilization, etc. are collected in rivers and lakes, and finally deposited in the sediment of the river channel. Secondary pollution. [0003] At present, the methods for river sediment treatment on the market include: dredging, pumping and releasing water, sand filling to cover, adding coagulation and curing agent, bioremediation, etc. Each of these approaches has its advantages and disadvantages. [0004] Sediment elution is based on the characteristics of small particle size of organic matter and suspended matter in water body and large particle size of inorganic sediment. Through physical disturbance, turbulent flow is generated at the mud-water interface, so that collo...

AI Technical Summary

Problems solved by technology

[0005] In view of the shortcomings of the existing sediment elution disturbance device 1: the air compressor used in the aeration device has a large environmental noise

not environmentally friendly

2: In rivers with hard or thick bottom mud, the bottom mud is often not disturbed by aeration and the disturbance is not obvious, and the treatment depth is not enough

3: The aeration or jet disturbance device is single, and if there is a failure, it will affect the construction and operation of the entire hull
