Movable pumping filter capable of hierarchy controlling the soil pick-up

Abstract

The invention provides a mobile suction filtering device which can control pollution absorption in layer separation way, and relates to the technical field of water purification, in particular to the technology of removing surface water pollution. The device is characterized in that: a suction pump, in which the rotating shaft is meshed with the output shaft of an electric motor, is provided; the suction end of the suction pump is connected with a backseat port of a suction head by a transportation flexible hose; the output end is connected to a water absorption inlet of a filter box; the water absorption inlet is connected with a geotextile bag in the filter box; the bottom side of the filter box is provided with an outlet with a filter screen; the components are all arranged in a framework which is structured by channel steels; wherein, in the framework, the base of the framework is a chassis, the middle is symmetrically provided with two large wheels, the back and the front are respectively provided with two small wheels and a carrying vehicle body which is formed by a push-and-pull railing is provided; the suction head can break away the vehicle body and the movement direction is operated by a catch bar independently. The suction head has rolling-type dirt absorption head and free-floating dirt absorption drum. The invention provides a simple, reliable and simplified sewage disposal unit for society; the device is characterized in that: different suction heads are used for dirt absorption according to different occasions, thus being a practical invention.

Description

technical field [0001] The invention relates to the technical field of water quality purification in the discipline of environmental engineering, and is a technology used for surface runoff, removal of subsurface mud, and removal of surface water pollution. Specifically, it is a mobile suction filter that can control pollution suction in layers device. Background technique [0002] The surface flow constructed wetland realizes the efficient purification of wastewater through filtration, adsorption, co-sedimentation, plant absorption and microbial decomposition. During the operation and treatment process, due to the comprehensive As a result, the thickness of the bottom mud will gradually increase; at the same time, wetland plants will also be deposited at the bottom of the wetland due to the fact that the dead branches and leaves of the wetlands enter the water and are not salvaged in time. The increase of the sediment thickness in the surface flow constructed wetland resul...

Problems solved by technology

Huzhou Huancheng River Dredging Project, Hangzhou West Lake Bottom Dredging Project, Jiaxing Nanhu Dredging Project and Wuxi Wuli Lake Ecological Dredging Project and other environmental protection dredging projects use small dredgers, mud pumps, Cutter suction dredgers, chain bucket dredgers, grab dredgers, etc. have a large interaction between dredging, transporting and unloading equipment, limited by water obstacles, inflexible deployment, and high cost

[0007] However, none of the above-mentioned equipment can complete layered control of sewage suction, that is, it cannot be applied to surface flow artificial wetlands and other small water bodies for sediment removal and floating debris removal when algal blooms erupt in water bodies, and the use is relatively simple.

And the equipment is limited by water obstacles, so the deployment is not flexible

All algae removal devices use coagulants such as aluminum salts and iron salts. As the tail water is discharged back to the water body, it will also bring new environmental pollution problems.
