An integrated device for domestic sewage treatment based on filler and sponge iron

Abstract

The invention discloses a domestic sewage treatment integrated device based on novel filler and spongy iron. The integrated device is formed by a closed cylinder, a sewage collecting pipe network is arranged at one side of the closed cylinder, the sewage collecting pipe network communicates with a water storage tank, the position, for sewage in the sewage collecting pipe network to enter the water storage tank, of the water storage tank, is provided with a buffer plate, a sludge pump is arrange at the bottom of the water storage tank, a sludge fermenting tank is arranged at the other end of the sludge pump, a pressure booster and a heater are arranged at the inner side of the sludge fermenting tank, the bottom end of the sludge fermenting tank is connected with a high temperature sterilization chamber, the high temperature sterilization chamber is directly connected to outside soil, a water pump is arranged at the middle part of the water storage tank, and the other end of the water pump is sequentially connected with a tower filter tank, a cage filler rack and an aerobic biomembrane reactor. The integrated device used for rural water treatment has the advantages of low running cost, small size, convenience in use, low price, and effective alleviation pollution of rural sewage to the environment, and is widely suitable for the treatment of domestic sewage by rural users.

Description

Technical field [0001] The invention relates to the technical field of sewage recovery and treatment, in particular to an integrated device for treatment of domestic sewage based on filler and sponge iron. Background technique [0002] Rural sewage has become a major component of water pollution due to the scattered regions, large population, and difficulty in collecting. Rural sewage contains a large amount of organic matter and inorganic salts such as nitrogen and phosphorus. [0003] With the advancement of science and technology, the living standards in rural areas have been continuously improved. However, while the living standards of rural residents have improved, their lifestyles have not changed accordingly. They still live according to the traditional lifestyle, such as direct domestic sewage discharge, and everywhere. Splash. As the residents in rural areas are scattered, it is impossible to treat domestic sewage uniformly, so the pollution of domestic sewage to water re...

AI Technical Summary

Problems solved by technology

Most of these methods have the characteristics of long residence time, poor treatment effect in winter, and poor removal effect of nitrogen and phosphorus in wastewater.

Therefore, the lack of existing rural domestic sewage treatment technology and the large discharge of nitrogen and phosphorus are the direct causes of serious eutrophication in domestic water bodies
