Abstract

The invention relates to a rural domestic sewage treatment system which comprises a water storage module and a percolation module; a water storage cavity is formed in the water storage module, the water storage module is provided with a first water inlet and a first water outlet, and the first water inlet is higher than the first water outlet; a percolation cavity is formed in the percolation module, the percolation module is provided with a second water inlet and a second water outlet, the second water inlet is higher than or flush with the second water outlet, and the second water inlet and the first water outlet are communicated and are the same in height; a percolation structure for sewage to pass through is arranged in the percolation cavity, the percolation structure comprises a first perforated plate, a multi-stage percolation layer and a second perforated plate, the multi-stage percolation layer comprises a quartz gravel layer, a first limestone gravel layer and a second limestone gravel layer, and the average particle size of the second limestone gravel layer is larger than that of the first limestone gravel layer; and the average particle size of the first limestone gravel layer is larger than that of the quartz gravel layer. According to the invention, the problems of poor harmless effect and poor sanitary condition of rural domestic sewage treatment are effectively improved.

Description

technical field [0001] The invention relates to domestic sewage treatment for raining, in particular to a rural domestic sewage treatment system. Background technique [0002] Most of the existing rural integrated domestic sewage treatment equipment or three-format septic tanks are integrated in one tank. After installation, they are often left unattended and maintained, and the integrated equipment is a customized product, which is sometimes difficult to meet the terrain conditions. There are problems such as poor harmless effect and poor sanitary conditions in the pool. Rural domestic sewage has the characteristics of scattered collection and concentrated discharge time. After dry toilets are changed to water toilets, the existing three-format septic tanks are often full-loaded or overloaded, resulting in poor harmless treatment effects and increased sewage discharge. problems, causing greater pollution, and even the formation of black and odorous water bodies. In order t...
