Miniaturized Kitchen Wastewater Purification Device

Abstract

The invention discloses a small-sized kitchen wastewater purification device, and relates to the kitchen wastewater purification device which comprises an anaerobic water storage tank and a filter groove, wherein the anaerobic water storage tank comprises a closed tank body; an inlet is arranged at the lower part of the tank body; two or more guide plates are arranged in the tank body; the upper ends of all the guide plates are arranged on the tank body; the lower ends of all the guide plates tend to gather together, so as to form a gathering opening; the guide plates divide the interior of the tank body into an upper layer and a lower layer; an exhaust escaping outlet and a tail water output pipe are arranged at the upper layer of the tank body; kitchen wastewater entering the tank body from the inlet in the lower part of the tank body is subjected to precipitation, anaerobic fermentation, and separation from floating objects, and then the treated kitchen wastewater overflows from the tail water output pipe and is outputted to the filter groove; the filter groove comprises a groove body of which the upper end is opened; a cinder layer is paved in the groove body; the treated kitchen wastewater entering the filter groove is purified after flowing through the cinder layer, and the purified kitchen wastewater flows from an outlet in the bottom of the filter groove. The small-sized kitchen wastewater purification device has the advantages that miniaturization of a purification device can be realized under the premise that kitchen wastewater is purified.

Description

technical field

[0001] The invention relates to the technical field of kitchen wastewater purification devices, in particular to a miniaturized kitchen wastewater purification device. 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 technology is a hig...
