Technical method for combining coagulating rotational flow filtering with multi-dimensional catchment wetland

Abstract

The invention relates to a technical method for combining coagulating rotational flow filtering with multi-dimensional catchment wetland. The method comprises the following three steps: magnetic intensifying flocculation, eddy deposition separation and artificial wetland purification; water is respectively subjected to flocculation reaction, pollutant deposition separation and artificial wetland filtering, so that water purification is realized; the method further comprises the step of recycling magnetic powder, so that the recycling of the magnetic powder is realized. According to the technical scheme, the flocculation, eddy, filtering, micro-biological degradation and artificial wetland techniques are jointly applied to an initial rainwater treatment device, the separation of pollutants in rainwater is intensified through the flocculation, eddy, filtering and artificial wetland techniques and the separated pollutants can be further degraded and removed through the micro-biological degradation technique. According to the technical method, the matters, such as suspended solids, greasy dirt and floats, in the rainwater can be removed to a great extent, and meanwhile, the technical method is capable of greatly reducing the land occupation.

Description

technical field [0001] The invention relates to a treatment method for initial rainwater, in particular to a process method combining coagulation cyclone filtration and multi-dimensional catchment wetland. Background technique [0002] With the rapid development of human beings, forests, wetlands, and grasslands in natural areas are constantly being replaced by roads, squares, buildings, etc., and the scale of cities is still expanding, and problems such as urban hydrology, water quality, and water resources have become increasingly prominent. A large number of studies have shown that particulate matter is the main carrier of various pollutants in runoff rainwater. In runoff rainwater, it plays the role of adsorbing pollutants in the early stage, transporting pollutants in the middle period, and releasing pollutants in the later settlement. At the same time, particulate matter itself affects the transparency of water bodies. , Turbidity is an important water quality index. ...
