Filtering pipeline type septic tank reaching standards

Abstract

In order to further improve the treatment efficiency of septic tanks reaching standards, the invention provides a filtering pipeline type septic tank reaching standards. The filtering pipeline type septic tank is mainly composed of an excrement residue tank, a water collecting tank, a clean water tank and a filtering pipeline tank, wherein the excrement residue tank is provided with pipeline typegrids; the water collecting tank is provided with a sewage lifting pump; the clean water tank is provided with a backwashing pump; the filtering pipeline tank is positioned above the excrement residuetank, the water collecting tank and the clean water tank; and the filtering pipeline tank is at least divided into two grids, each grid of the filtering pipeline tank is provided with a group of or multiple groups of filtering pipelines, and the filtering pipelines are mutually communicated through filtering pipeline connecting pipes. Pollutants in sewage are removed through biological contact oxidation, anaerobic biochemical reaction, aerobic biochemical reaction as well as filtration and precipitation action in the facilities.

Description

technical field [0001] The invention belongs to the field of water pollution control and sewage treatment, and in particular relates to a filtering pipeline type septic tank which meets the standard of direct discharge or reuse. Background technique [0002] Septic tanks are an important pretreatment facility for domestic sewage. However, purely using septic tanks to treat domestic sewage cannot meet the relevant standards for direct discharge or reuse. It requires advanced treatment before direct discharge or reuse. However, the investment and operating costs of the scattered domestic sewage advanced treatment facilities are high, so the sewage collection pipe network is built to collect the scattered sewage and then a centralized sewage treatment plant is built for advanced treatment. This is the domestic sewage treatment mode of "septic tank + sewage collection pipe network + centralized sewage treatment plant" widely used at present. [0003] The investment and operatio...
