Multi-stage intercepting and purifying device for suspended particulate organic matter

Abstract

The invention discloses a multi-stage intercepting and purifying device for suspended particulate organic matter, and relates to the field of water environment research. The multi-stage intercepting and purifying device is mainly used for intercepting and purifying various fine particulate suspended solids in a river channel. According to the technical points, the multi-stage intercepting and purifying device includes an aquatic plant filtering device, an electric flocculation device and an ultrafiltration membrane pool. The multi-stage intercepting and purifying device for the fine particulate suspended solids is provided in view of deficiencies in the prior art, and the multi-stage intercepting and purifying device can solve the multi-stage processing problem of the fine particulate suspended solids of the river channel and rivers, and is simple in structure, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to the field of water environment research, in particular to a multi-stage interception and purification device for suspended particle organic matter. Background technique [0002] In recent years, with the development of the economy, the acceleration of urbanization and the increase of population density, the pollution of rivers in my country has become more and more serious. The pollutants in rivers mainly come from surface runoff, which will carry a large amount of suspended matter into the river during the runoff process. , resulting in water pollution or river blockage. Part of the pollutants entering the river exist in dissolved form, and some are absorbed by suspended solids. Large-sized suspended solids usually settle naturally, while fine-particle suspended solids migrate with the river, causing water pollution. It can be seen that the fine particle suspended matter in the water body is one of the important causes of rive...
