Foam plugging type microbial decomposition water circulating environmental protection toilet for islands

Abstract

The invention relates to a foam plugging type microbial decomposition water circulating environmental protection toilet for islands. A process for treating liquid dung comprises the following steps of: allowing excrement and urine which are washed by foam to enter a biochemical box to perform primary treatment, separating and depositing to remove foreign matters and impurities in water, and regulating the liquid dung; allowing the liquid dung to enter anaerobic and aerobic biochemical systems to perform secondary treatment, and adding microbial strains special for excrement degradation, so that most of organic matters in sewage are decomposed gradually to form colourless and inodorous gas and trace inorganic matters, and the water quality is purified; and finally, performing tertiary treatment on the water, and removing chromaticity, odor, germs and the like in the water through filtering, aeration, adsorption and micro-filtration. In the foam plugging type microbial decomposition water circulating environmental protection toilet, microbes can decompose the excrement completely so as to meet requirements of non-pollution discharge and no need of sewage pipelines, the excrement can be decomposed in about 20 hours, the decomposition rate is over 90 percent, and decomposition products are water vapor, carbon dioxide, organic acid and the like; and the toilet can improve the environment obviously and has the obvious economic and social benefits.

Description

technical field [0001] The invention relates to a foam-blocking microbial water-decomposing circulation environment-friendly toilet for sea islands. Background technique [0002] Since the reform and opening up, my country's economy has developed rapidly and the national level has been continuously improved. However, these gratifying statistics are accompanied by the destruction and pollution of a large amount of water, air, land and other natural environments. Among them, domestic sewage accounts for a large proportion of all water pollution. According to statistics, the excrement discharged per person per day contains 18.6 grams of nitrogen and 1.74 grams of phosphorus, which can pollute 10 tons of clean water bodies. Half of urban domestic sewage. The current mainstream approach for these domestic sewage is to discharge the sewage into the sewage treatment plant through municipal pipelines for treatment and in-situ degradation treatment. Although the treatment method o...

Problems solved by technology

Although the treatment method of the sewage treatment plant can treat the sewage well, it has great limitations, such as the high cost of sewage transportation, and the laying of sewage pipelines in some remote or special places such as mountains and islands is not easy

[0003] The in-situ degradation treatment method is a feces water treatment technology that started in recent years. The feces are degraded on the spot by microorganisms and attached devices, so as to achieve the effect of no need to discharge and no pollution. High power consumption, high ability to adapt to the microbial environment, easy to die, low system failure resistance, easy to be blocked by other objects other than feces, low daily feces processing capacity, too much feces will cause system saturation until paralysis, cumbersome management , increasing the daily workload of managers

[0004] In recent years, due to the acceleration of island development and the intensification of human activities, the resulting excrement disposal has also become an important issue. Due to the inconvenient transportation and poor municipal infrastructure on the island, conventional excrement disposal methods are not applicable

For example, the pipe network and septic tanks commonly used on land do not meet these conditions, so most of the excrement in the island area has the problem of being directly dumped into the sea, and the resulting environmental pollution is quite serious, especially for some Tourist islands, the influx of a large number of tourists in a short period of time, the excrement problem caused by this is even more serious
