A water purification device and purification method for point source water pollution

Abstract

The invention discloses a water quality purification device and a purification method for dealing with point source water pollution. The purification pool body includes a central pool and an outer ring pool; the outer ring pool is divided into coarse filtration and purification half pools, The semi-tank is purified by fine filtration; one end of the semi-tank is connected to the water inlet on the outer wall of the purification tank through a pipeline, and the other end is connected to it through the water injection mesh provided in the central pool; the inner bottom of the central pool is provided with an aeration network pipe, The side is equipped with a biological filter material floating plate, and there are multiple sets of card holes on the biological filter material floating plate; The water injection port is connected, and the other end of the fine filter purification half pool communicates with the outside world through the water outlet provided on the purification pool body. The invention can effectively improve the travel path of coarse filtration and fine filtration, and improve the aeration treatment effect of the biological filter material, so as to improve the treatment effect of sewage water quality purification.

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
