Water quality purification device for coping with point source water pollution and purification method thereof

Abstract

The invention discloses a water quality purification device for coping with point source water pollution and a purification method thereof. The device comprises a purification tank body; the purification tank body comprises a central tank and an outer ring tank; the outer ring tank is equally divided into a rough filtration purification half tank and a fine filtration purification half tank by a partition plate; one end of the rough filtration purification half tank is connected with a water inlet in the outer wall of the purification tank body through a pipeline, and the other end is communicated with a water injection mesh formed in the central tank; an aeration net pipe is arranged at the bottom in the central tank, a biological filter material floating plate is arranged above the central tank, and a plurality of groups of clamping holes are formed in the biological filter material floating plate; the upper end of the water quality purification assembly is communicated with a flow guide pipe through a telescopic hose, the flow guide pipe is connected with a water injection port formed in one end of a fine filtration purification half tank, and the other end of the fine filtration purification half tank is communicated with the outside through a water outlet formed in a purification tank body. The travel paths of rough filtration and fine filtration can be effectively improved, and the aeration treatment effect of the biological filter material is improved, so that the sewage quality purification treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a water purification device and a purification method for dealing with point source water pollution. Background technique [0002] As far as water pollution is concerned, point source pollution mainly includes industrial wastewater and urban domestic sewage pollution, usually with fixed sewage outlets for centralized discharge. Non-point source pollution refers to dissolved and solid pollutants relative to point source pollution. From a non-specific location, under the action of precipitation (or snowmelt) erosion, it flows into the receiving water body through the runoff process and causes eutrophication or other forms of pollution of the water body. [0003] With the continuous development of society, people are paying more and more attention to the pollution caused by factories to the environment, especially water pollution. Therefore, more and more researchers have de...

Problems solved by technology

[0004] However, most of the existing water purification devices often occupy a large area and use multiple pools for water purification. Although a few devices integrate different processes in one device, their filtration path is short. If it is necessary to increase the filtration path It is necessary to increase the volume of the device, so it is difficult to achieve the desired effect, so a new type of water purification device is needed to solve the above-mentioned problems
