Wall surface outer-hanging type kitchen wastewater vertical purification system

Abstract

The invention discloses a wall surface outer-hanging type kitchen wastewater vertical purification system, and in particular relates to a kitchen wastewater purification device comprising multiple wastewater treatment units arranged on an exterior wall of a tall building, wherein each wastewater treatment unit is used for treating the kitchen wastewater of residents of a corresponding floor respectively; an anaerobic water storage tank and a filter tank are arranged in each wastewater treatment unit; the anaerobic water storage tank comprises a closed tank body; the kitchen wastewater of the residents of the same floor are collected in a wastewater input pipeline by virtue of respective drainage pipelines and is delivered into the anaerobic water storage tank corresponding to the floor in a unified mode for anaerobic fermentation and preliminary residue-water separation; the wastewater treated by the anaerobic water storage tank is delivered into the filter tank by virtue of a wastewater output pipeline; the filter tank comprises a tank body with an open upper end, a cinder layer is paved in the tank body, and the wastewater entering the filter tank is purified after flowing through the cinder layer and is delivered to a tail water collecting pipe for discharging. The wall surface outer-hanging type kitchen wastewater vertical purification system disclosed by the invention can be used for realizing miniaturization and three-dimensional structure of purification systems while being capable of purifying the kitchen wastewater.

Description

technical field [0001] The invention relates to the technical field of kitchen wastewater purification devices, in particular to a wall-mounted three-dimensional kitchen wastewater purification system. Background technique [0002] The miniaturization and three-dimensionalization of constructed wetland and quasi-constructed wetland sewage purification systems have become the development direction of sewage treatment technology in my country. Unlike developed countries such as Europe and the United States, which are driven by home-based and miniaturized wastewater treatment technologies, a major reason for the development of miniaturized and three-dimensional artificial wastewater treatment technologies in my country is that the conflict between man and land is greater than that in European and American countries. Traditional constructed wetlands occupy a large area, and the hydraulic retention time of sewage in constructed wetlands is long. Although the constructed wetland t...

Problems solved by technology

Due to the shading effect between layers, the constructed wetland will be forced to be relatively narrow

Therefore, it will be very difficult for this kind of purification system to coordinate the purification effect and efficiency. If the relevant parameters are not set properly, it may be difficult to achieve the expected effect.

Although the above-mentioned technical solutions vary widely in implementation methods, the basic principles they follow are the three typical structures of traditional constructed wetlands. Due to the inherent technical limitations of constructed wetland technology itself, the actual effect in terms of miniaturization and three-dimensionalization is still relatively small. limited
