Black odorous river course ecological treatment system and treatment method thereof

Abstract

The invention provides a black odorous river course ecological treatment system which comprises an infiltration island, submerged plants and an internal electrolysis substrate, wherein the internal electrolysis substrate comprises a composite substrate cushion layer and an internal electrolysis reaction filler; and the composite substrate cushion layer comprises gravel, haydite and zeolite. The treatment method comprises the following steps: establishing the infiltration island; growing the submerged plants in the restoration river reach; and laying the composite substrate cushion layer on the riverbed of the river course, and adding the internal electrolysis reaction filler into the substrate cushion layer to complete the laying of the internal electrolysis substrate. According to the black odorous river course ecological treatment system and treatment method thereof, the submerged plants are utilized to perform the functions of purifying water; and the purification of the infiltration island and the reinforced purification of the internal electrolysis substrate are utilized to improve the oxygen environment in the river course. The system quickly decomposes, absorbs and converts the black odorous substances, enhances the dephosphorization efficiency, can quickly improve the black odorous phenomenon of the water body, and also has an active promotion action on the aquatic ecosystem of the river course.

Description

technical field

[0001] The invention relates to the technical field of river course management, and more specifically, relates to an ecological treatment system for black and odorous river courses and a treatment method thereof. Background technique

[0002] At present, with the development of cities and the improvement of industrial and agricultural production levels, a large amount of domestic sewage, rainwater and garbage flow into the river, polluting the water body of the river, and the river has shortcomings such as small water environment capacity and poor self-purification ability of the water body, which leads to the loss of oxygen supply to the water body. The oxygen consumption is unbalanced, the water body is anoxic or even anaerobic, and the COD, BOD, and NH in the water body 3 If the content of -N is too high, the anaerobic decomposition of organic matter in the water body will cause black odor, which will cause a crisis in the entire ecosystem and seriously af...
