Abstract
A rural domestic sewage treatment system is characterized in that a liquid inlet pipe of a raw water collecting tank is provided with a grid; the raw water collecting tank is connected with a liquid pump through a liquid inlet pipe and a liquid outlet pipe; an aeration device is arranged on the liquid inlet pipe and the liquid outlet pipe; the aeration device is provided with an air inlet pipe; a settling tank is fixed above the raw water collecting tank, an overflow plate is fixed on the settling tank, and one side of the settling tank is connected with a liquid discharge pipe; the sedimentation tank is connected with a sludge pump through a sludge pipe; the sludge pump is connected with the liquid inlet pipe. After garbage is separated by grids, sewage and liquid dung discharged by village households enter a raw water collecting tank, liquid in the raw water collecting tank forms vortex under the action of a liquid pump and an aeration device, fermentation treatment is carried out by combining bacterial liquid, flowing liquid enters a settling tank through an overflow plate, sludge is settled, clear water is discharged through a liquid discharge pipe, and the sludge is pumped out by a sludge pump and then enters the raw water collecting tank for circulation treatment after being filtered by the grids. Effectively collect domestic sewage and liquid dung in the village, centralize and efficiently treat the domestic sewage and the liquid dung, improve the living environment and reduce the sewage discharge pollution of the village.
Description
Technical Field
The utility model belongs to the technical field of sewage treatment, concretely relates to rural area domestic sewage treatment system.
Background
The basic material in the toilet is human excrement, and the excrement in the toilet is not well treated: in rural areas and other areas, substances in the toilet are generally treated in modes of composting or transferring to landfill and the like because a sewer network is not arranged; the septic tank is a necessary device equipped in each district of city and countryside in China, and 13.6 million people in China generate over hundred million tons of fecal sludge every year. According to the national regulation, the septic tank is required to be a cleaning period of 3 months to 1 year, and a large amount of excrement sludge is cleaned and transferred, so that secondary pollution is caused to the surrounding environment. Therefore, the problem of harmless treatment of the sludge in the septic tank is solved in situ, the cleaning work is reduced, and the sludge in the septic tank is not used as a pollution source of water pollution, which is urgent.
