Water self-circulating emission-free complete decomposing type bio-environmental protection toilet

Abstract

Directed at the current situation of the prior art and based on a circulating water flushing type ecological toilet, the invention aims to realize self-circulation, no emission, no picking and complete decomposition of water flushing type toilets. Through a current reactor and by the mode of anaerobiosis, anoxia, aerobiosis, anoxia, and anaerobiosis, a biological rotating disc is designed into a facultative pond with a special structure. A wood fiber bio-carrier bed is employed, and an ultrasound technology is adopted to perform a new internal circulation stirring process in the biological rotating disc facultative pond, an upflow type anaerobic tank, and an anoxic tank so as to accelerate decomposition and digestion of organic matters. Meanwhile, electro-adsorption, high-energy physics, an anaerobic and aerobic wood fiber integrated facultative tank and other technologies are adopted to conduct water treatment on fecal sewage. The invention can achieve through and complete decomposition of organic matters and eliminate malodor. The bio-environmental protection toilet needs no water supply, and the first supplied water can be circulated for use, so that no more water needs to be added. The toilet provided in the invention is an environmental protection toilet having no residue, precipitate, emission or pollutant.

Description

Technical field: [0001] The invention aims to solve the self-circulation, no discharge, no extraction and complete decomposition of flushing toilets, relates to biological regeneration treatment of toilet sewage, and belongs to the field of renewable energy for environmental management and water resources development. Background technique: [0002] The toilet plays an important role in people's daily life. It receives, accumulates and eliminates most of the pollutants excreted in human's daily physiological activities every day. After these manures are discharged into urban sewers, they become the main source of pollutants in domestic sewage and are also an important part of urban sewage pollutants. Therefore, the traditional flush toilet is the main source of wasting and polluting water resources, and the flush toilet invented by the West is no longer in line with today's scientific development concept. With the development of technology, domestic and foreign countries are...

AI Technical Summary

Problems solved by technology

[0003] 1) The circulating water flushing ecological toilet generally needs to be equipped with a membrane module processing unit, which is easily polluted by inorganic salts, has high operating requirements, high power consumption (electricity costs more than 5,000 yuan), low degree of reduction, and poor sterilization Thoroughly, in order to reduce the odor, it is necessary to regularly and timely discharge sewage and replenish clean water. There is a tendency to accumulate pollutants. When the number of people is overloaded, the biological treatment effect is poor, and the biological treatment still follows the anaerobic-anoxic-aerobic-anoxic-anaerobic pattern. This method is very passive, the decomposition is not complete, and the processing is slow.

[0004] 2) Water-free packaged ecological toilets have high cleaning and transportation costs and poor working environment. During the cleaning and transportation process, excrement is likely to leak and cause secondary pollution, and some packaging materials are not easy to degrade

[0005] 3) Water-free microbial composting type ecological toilet has a single degrading bacteria species, aerobic type consumes a lot of power, anaerobic type has serious secondary pollution, and the degree of reduction is not high. It is necessary to consider the outlet of organic fertilizer

[0006] 4) At present, the problem of water-free degradable ecological toilets is: the original species of microorganisms used still depend on imports from Japan, and the cost is high, accounting for about 15% to 20% of the price of a single squatting host for 200 person-times of feces and urine per day; There are still many difficulties in the localization of key technologies in terms of species screening, domestication, strengthening, and purification, which are a restrictive factor for industrialization: it is still a difficult problem to maintain the normal operation of the bioreactor when the proportion of urine is large
