Multilevel recycling treatment device for river sludge

Abstract

The invention discloses a multilevel recycling treatment device for river sludge. The device includes a river dredging hull, two first-level sludge recycling tanks, a second-level sludge dewatering device and an adsorption mechanism. The top of the river dredging hull is fixedly provided with the first-level sludge recycling tanks. The two first-level sludge recycling tanks are symmetrically arranged on the two sides of the top of the river dredging hull, the portion, between the two first-level sludge recycling tanks, of the river dredging hull is provided with the second-level sludge dewatering device, the tops of the two first-level sludge recycling tanks are fixedly provided with sewage suction pumps. The device has a simple and reasonable structure, the ecological environment of a river channel is effectively improved, river sludge recycling treatment and control are achieved, multilevel sludge dewatering and recycling are achieved, the load of the river dredging hull is reduced,mechanical dewatering is not required, the energy consumption and cost of the sludge recycling treatment are reduced, and filtration, adsorption and purification are carried out during dewatering so as to improve the river water quality.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of river treatment, and particularly relates to a multi-stage recovery treatment device for river sludge. [0003] Background technique: [0004] River improvement is also called “river bed adjustment”. The engineering measures to control and rebuild the river channel. Erosion and siltation often occur in natural rivers, which are prone to water damage and hinder the development of water conservancy. Remediation, including control, dredging and bank protection, etc., but the current river treatment is carried out by river dredging vessels. In order to reduce the load-bearing weight of the hull, the dredged sludge needs to be mechanically dewatered. However, the mechanical dewatering equipment itself has some problems. Heavy weight, high driving energy consumption is required for mechanical dewatering, which increases the energy consumption and cost of river sludge recovery treatment, and has poor practicabi...

AI Technical Summary

Problems solved by technology

[0004] River regulation is also known as "river bed consolidation". The engineering measures for controlling and transforming rivers often cause erosion and deposition in natural rivers, which are prone to water damage and hinder the development of water conservancy. Remediation, including dredging, revetment and other projects, but at present river dredging ships are used for river channel regulation. In order to reduce the carrying weight of the hull, it is necessary to mechanically dewater the dredged sludge, but the mechanical dewatering equipment itself has problems. Large weight, and mechanical dehydration needs to use higher drive energy consumption, which increases the energy consumption and cost of river sludge recovery and treatment, and has poor practicability. Therefore, the present invention provides a multi-stage recovery and treatment device for river sludge to solve the above-mentioned problems. question
