Water-saving zero-emission ecological toilet system and sewage treatment method

Abstract

The invention discloses a water-saving zero-emission ecological toilet system and a sewage treatment method. The water-saving zero-emission ecological toilet system comprises a toilet room and an ecological treatment device, wherein the toilet room comprises a toilet stool and a foot power toilet flushing device; the toilet stool communicates with the ecological treatment device through a water inlet pipe; the ecological treatment device is divided into a first cell, a second cell and a third cell by partition plates; excrement is subjected to anaerobic fermentation in the first cell to generate biogas to be discharged; excrement residues, non-degradable substances and sludge are cleared and discharged out; and excrement sewage is subjected to deep anaerobic treatment in the second cell, then flows into the third cell for filtration, adsorption and purification, and communicates with the ecological treatment device through a water outlet pipe, so a circulating system is form, and sewage recycling is realized. The system provided by the invention has two characteristics of water saving and zero emission, relieves the problems of water resource shortage and rural water pollution, prevents odor leakage and mosquito breeding, and purifies air. The invention provides a system applicable to being used in rural areas with water resource shortage.

Description

technical field [0001] The invention relates to a novel ecological treatment device, in particular to a water-saving zero-discharge ecological toilet system and a sewage treatment method. [0002] technical background [0003] At present, the main cause of water environment pollution is the discharge of waste water from human life and production activities into the environment. With the improvement of human living standards, people pay more and more attention to the problem of water pollution. Some household toilets in new rural areas use ordinary rural sewage treatment devices to treat the wastewater generated in people's daily life. Compared with the previous dry toilets, although the environmental quality has been effectively improved, the use of ordinary rural sewage treatment devices will increase the daily water consumption of farmers. , the practicability of the arid rural areas is greatly reduced; secondly, the wastewater treated by ordinary sewage treatment equipmen...

Problems solved by technology

Some household toilets in new rural areas use ordinary rural sewage treatment devices to treat the wastewater generated in people's daily life. Compared with the previous dry toilets, although the environmental quality has been effectively improved, the use of ordinary rural sewage treatment devices will increase the daily water consumption of farmers. , the practicability of the arid rural areas is greatly reduced; secondly, the wastewater treated by ordinary sewage treatment devices must be regularly pumped and sent to the sewage pipe network or directly discharged into the surrounding environment or water bodies, which not only causes a certain impact on the environment degree of pollution, but also increase the workload, and even lead to mosquito breeding in summer
