Abstract

The invention relates to the technical field of pollution control of water environments. Aiming at the problem that sewage at sewage discharge outlets of the periphery of a landscape lake easily affects the water quality of the landscape lake, the invention provides a sewage treatment system for the sewage discharge outlets of the landscape lake. The sewage treatment system is characterized by comprising a planting region surrounding each sewage discharge outlet, wherein the planting region is used for planting aquatic plants; the distance between each planting region and each sewage dischargeoutlet is 3 to 20 m; and the width of each planting region is 1 to 8 m. The planting regions are arranged in water inlet positions of the sewage discharge outlets of the landscape lake in a way of surrounding the sewage discharge outlets; the aquatic plants are planted in the planting regions; the roots of the aquatic plants can easily absorb bottom mud and organic substances in the sewage, and the bottom mud and the organic substances are used as nutrient substances; oxygen gas is released, so that organic matters in water is subjected to a chemical reaction with the oxygen gas, and thus, the organic substances in water can be decomposed, and carbon, nitrogen, phosphorus and the like in the sewage can be fixed onto rhizomes of the aquatic plants; and the content of ammonia nitrogen and the phosphorus in the sewage can be favorably reduced, so that water discharged into the landscape lake from the sewage discharge outlets cannot easily affect the water quality of the landscape lake.

Description

technical field

[0001] The invention relates to the technical field of water environment pollution control, more specifically, it relates to a sewage treatment system for a landscape lake sewage outlet. Background technique

[0002] Landscape lakes are generally artificial lakes, which are a kind of lake dug out by people in a planned and purposeful manner, and are produced in an unnatural environment.

[0003] Generally, when the landscape lake is constructed, aquatic plants and aquatic animals will be planted in the lake to build the ecosystem of the landscape lake, so that the landscape lake has a certain self-purification function. However, due to municipal needs, the surroundings of the landscape lake are usually connected to the sewage outlet. Municipal domestic sewage, industrial sewage and other sewage will enter the landscape lake through the sewage outlet. When the pollution speed of the sewage is faster than the self-purification speed of the landscape lake, It i...
