Embodiment Construction

[0011] Below in conjunction with embodiment the present invention is described in further detail.

[0012] The biological-ecological composite sewage treatment pool includes a plurality of filter units arranged in sequence, and each filter unit includes a pool surrounded by an upstream retaining dam on three sides, a downstream retaining dam on one side, and an outlet water distribution device located on the side of the downstream retaining dam. canal;

[0013] Among them, the height of the downstream retaining dam is higher than that of the upstream retaining dam;

[0014] And the pond body of each filtration unit is provided with aquatic plants, biological filler and the water outlet collecting pipe that is positioned at the bottom of the pond body successively from top to bottom, and the outlet of this water outlet collecting pipe stretches out on one side of the downstream retaining dam and is connected with the described water outlet. The water distribution channel is co...

Abstract

The invention discloses a biological-ecological composite sewage treatment tank. The biological-ecological composite sewage treatment tank comprises multiple filtering units arranged in an order. Each one of the multiple filtering units comprises a tank formed from three upstream water retaining dams and one downstream water retaining dam, and an outlet water distribution ditch located at one side of the downstream water retaining dam. The downstream water retaining dam is higher than the upstream water retaining dams. An aquatic plant, biological stuffing and an outlet water collector pipe are orderly arranged in the tank of each one of the filtering units from top to bottom. The outlet of the outlet water collector pipe stretches out of one side of the downstream water retaining dam and is communicated with the outlet water distribution ditch. In two adjacent filtering units, the outlet water distribution ditch of the prior filtering unit is adjacent to the upstream water retaining dams of the next filtering unit.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment pool which adopts a biological-ecological composite method and can effectively remove nitrogen and phosphorus in sewage. Background technique [0002] The eutrophication of river water is an increasingly serious and global water environment problem. In slow-flowing water, nutrients such as nitrogen and phosphorus will cause excessive growth of algae and aquatic plants, and lead to a sharp decrease in dissolved oxygen in the water, causing a large number of fish to die. When the eutrophication of the water body is serious, it will also lead to the degradation of the lake and even the demise of the water body. Moreover, at present, a lot of sewage is directly discharged into rivers without treatment, causing more serious eutrophication and pollution of rivers in many cities, and posing a serious threat to water supply sources and the living and living e...
