Rural wastewater AO treatment device and rural wastewater treatment system

Abstract

The invention discloses a rural wastewater AO treatment device and a rural wastewater treatment system, and belongs to the technical field of water treatment devices. The AO treatment device comprises an AO anaerobic treatment area and an AO aerobic treatment tank, wherein the AO anaerobic treatment area is arranged above the AO aerobic treatment tank; the AO anaerobic treatment area is filled with AO anaerobic filler, and an anaerobic treatment water outlet pipe is arranged at the side part of the AO anaerobic treatment area; and the AO aerobic treatment tank comprises a water falling area and an aerobic filler area, the water falling area is correspondingly arranged below the anaerobic treatment water outlet pipe, the water falling area communicates with the bottom of the aerobic filler area, water in the water falling area can be introduced into the aerobic filler area through the bottom of the aerobic filler area, and the water body is subjected to sufficient AO treatment. In addition, the operation process of the wastewater treatment system completely depends on the gravity effect and the self-pushing effect of water flow; the device is simple in structure, modularized and easy to maintain; and the device is miniaturized, is suitable for rural single-door and single-family, and treats rural domestic grey water from the source.

Description

technical field [0001] The present invention relates to the technical field of water treatment devices, and more specifically, relates to a rural wastewater AO treatment device and a rural wastewater treatment system. Background technique [0002] With the development of society, more and more water resources are used, making rural domestic sewage an important factor affecting the water environment. According to the pollution degree and source of sewage, it can be divided into gray water and black water. Gray water mainly includes kitchen sewage, laundry and bathing sewage, etc., and black water mainly includes toilet feces and sewage, etc., and black water is generally stored in a closed container with feces. In the container, the fertilizer formed by anaerobic fermentation is used to irrigate the vegetable field, which is conducive to improving soil fertility and generating certain economic value. Compared with black water, although gray water accounts for 50%-80% of the ...
