Ecological dredging integrated system

Abstract

The invention discloses an ecological dredging integrated system including a sludge dredger boat, a dehydration boat and a pumping device; the sludge dredger boat and the dehydration boat are connected by the pumping device, dug-up sludge is conveyed to the dehydration boat, the dehydration boat comprises a boat body, a sand removing device, a dewatering device and a dewatering sludge storing device, the sand removing device and the dewatering device are arranged on the boat body, the pumping device, the sand removing device, the dewatering device and the dewatering sludge storing device are connected in sequence for formation of a sludge treatment pathway. The ecological dredging integrated system can be used for dredging out of polluted bottom sludge in a riverway, dehydration, and other a series of treatment, dehydrated dry sludge can be further processed to achieve resource utilization, ecological dredging, reducing and harmless treatment and resource utilization can be realized, and accumulation and serious pollution problems of the bottom sludge in a river and lake can be solved.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to an integrated ecological dredging system. Background technique [0002] With the development of urban economy and the increase of population, a large amount of various industrial wastewater and domestic sewage are discharged into the river network, and the quality of water environment is deteriorating day by day, which has become a major problem restricting the sustainable development of economy. Industrial wastewater and domestic sewage are discharged into rivers, causing serious pollution of a large number of urban rivers. The deterioration of the water quality of the river has had many adverse effects on the water supply source, the water environment, and the aquatic ecology; the situation is particularly serious in the Yangtze River Delta and the Pearl River Delta. [0003] Pollution enters rivers, lakes, and reservoirs, and a large number of pollutants are deposite...

AI Technical Summary

Problems solved by technology

[0003] Pollution enters rivers, lakes, and reservoirs, and a large number of pollutants are deposited in the bottom mud, forming new pollution sources, reducing the self-purification ability of rivers, lakes, and reservoirs, and causing the gradual deterioration of the water environment of rivers, lakes, and reservoirs; at the same time, most reservoirs Eutrophication has also appeared, which has seriously affected the drinking water safety and living environment of people around rivers, lakes and reservoirs, reduced people's quality of life, and restricted the construction and development of regional economy
