Abstract

The invention provides an ecological treatment system for purifying sewage. The system comprises an artificial wetland device. The artificial wetland device comprises a drainage device, which is fixedat the bottom of the artificial wetland device; a filter layer, which is laid on the surface of the drainage device; water distribution equipment, which is buried in the surface layer of the filter layer; and aquatic plants, which are planted in the filter layer. A sewage disposal port is formed in the upstream end of the drainage device and is used for cleaning sediments in the drainage device.The sewage disposal port is formed in the upstream end of the drainage device, sediments deposited in the drainage device are cleared away through the sewage disposal port, the drainage device is prevented from being blocked by the sediments, and normal operation of the ecological treatment system is guaranteed. Meanwhile, by utilizing the ecological treatment system for purifying sewage, pollutants such as SS, BOD, nitrogen, phosphorus, heavy metals and the like can be effectively removed from polluted water.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an ecological treatment system for purifying sewage. Background technique [0002] Constructed wetland ecological sewage treatment system has been widely used all over the world due to its low construction and operation cost, strong decontamination ability, long service life, simple process, and diversified combinations. It relies on the synergy of physical, chemical, and biochemical reactions among the substrate, aquatic plants, and microorganisms in the wetland system to treat wastewater. Because the constructed wetland has stable effluent quality, low investment, low energy consumption, strong impact resistance, and easy operation. The features of simplicity and low operating cost have been widely used. [0003] However, after the existing constructed wetlands are put into operation for a period of time, they face the dilemma of system pipeline blockage. Excessive bl...
