Problems solved by technology

The problems in drainage are mainly manifested in: First, in many newly built houses and renovation of sanitation facilities in old houses, although there are three-format septic tanks, there are no discharge facilities, but rely on soil infiltration. Although this method is simple, it does not Seriously polluted the surrounding groundwater; but even if there is a drainage system, most of them are combined drainage systems, and open ditch drainage is generally used. Due to the lack of

Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] refer to figure 1 It can be seen that the rural domestic wastewater treatment process includes the following steps:

[0015] A. Rural domestic wastewater is introduced into the grid well, filtered through a mechanical fine grid, and the large particles of impurities in the filtered wastewater form grid slag, which is concentrated and transported out regularly;

[0016] B. Introduce the effluent from step A into the regulating tank, and aerate and stir through the perforated aeration tube built in the regulating tank, so that the sewage is homogeneous and even in quantity;

[0017] C. Intro...

Abstract

The invention relates to a domestic sewage treatment technology, and in particular relates to a rural domestic wastewater treatment process. After large impurities are removed by virtue of fine screen of a screen well, sewage enters into a regulating tank, and a perforated aerator pipe is arranged inside the regulating tank for aerating and stirring, so that the sewage is homogenous in quality and quantity; then the sewage automatically flows into an anaerobic-aerobic tank (A/O); due to the functions of aerobic and aerobic microorganisms, organic matters are decomposed into CO2 and H2O so as to remove most organic matters, and nitrification liquid from the tank O returns into the tank A to remove ammonia nitrogen; water discharged from the tank O automatically flows into a secondary sedimentation tank to remove suspended solids; and water from the secondary sedimentation tank is discharged on standard. The wastewater treatment process disclosed by the invention is high in removal efficiency, stable in operating performance and low in treatment cost.

Description

technical field [0001] The invention relates to domestic sewage treatment technology, in particular to a rural domestic sewage treatment process. Background technique [0002] Rural domestic sewage includes washing, bathing, kitchen cooking, excrement and its flushing and other drainage. Due to the unbalanced development of the rural economy, the quantity and quality of rural domestic sewage vary greatly from place to place. feature. The existing discharge methods of domestic sewage in rural areas are mainly sprinkled directly on the ground, discharged into nearby rivers or into rivers through sewers, etc. The problems in drainage are mainly manifested in: First, in many newly built houses and renovation of sanitation facilities in old houses, although there are three-format septic tanks, there are no discharge facilities, but rely on soil infiltration. Although this method is simple, it does not Seriously polluted the surrounding groundwater; but even if there is a drain...
