Technical Field

The utility model relates to an environmental protection processing apparatus field specifically is a used environmental protection biochemical treatment system in removal lavatory.

Background

In recent years, with the rapid development of the economic society and the continuous improvement of the modernization level, the water consumption of people is continuously increased, and in addition, the water resource shortage, pollution and waste are caused, the contradiction between the supply and the demand of fresh water is increasingly prominent, and the sustainable development of the human economy is seriously influenced. Therefore, water conservation has become an important topic of national concern. Over the past 50 years, the global demand for fresh water has increased by a factor of 2, and many places today are suffering from long-term shortages of fresh water, and pollutants also seep into groundwater through sewers, septic tanks, pit toilets, sewage basins, and the like. Therefore, the popularization of the mobile toilet in life brings much convenience to people, the range is wider and wider, the mobile toilet is not limited by any working environment, the appearance structure is light and handy, the color matching is reasonable, and the mobile toilet is suitable for stations, docks, tourist attractions, villas, newly-built communities, large construction sites, squares, densely-populated public places, luxurious commercial streets and the like.

In our human production and life, with the increasing population and high concentration, the yield of the excrement is continuously increased, and the environmental protection treatment of the excrement is a difficult problem in all countries in the world all the time. At present, the modern high-tech technology is developed at a high speed, and the pollution-free high-tech biochemical treatment technology for excrement splits another green channel, thereby having profound significance for ensuring environmental sanitation and human health. The excrement contains a large amount of impurities and suspended matters, the pollutants are loaded, and the excrement is different from common domestic sewage, generally about 350ml of excrement is discharged by an adult every day, and 150-200 ml of urine is discharged. About 97% of the components in the feces are water and 3% are solids. 30% of the solids are dead bacteria, 10-20% are fat, 2-3% are protein, 10-20% are inorganic salts, and 30% are solid components in undigested residual food and digestive fluids, such as exfoliated epithelial cells. The odor of feces is caused by products of bacterial action, mainly indole, skatole, mercaptans and hydrosulphides. Urine contains various substances that are cleared from the blood by the kidneys, and the normal components are: 3g/L of sodium, 0.19g/L of potassium, 0.36g/L of magnesium, 4.69g/L of chlorine, 0.84g/L of carbonate, 5g/L of phosphate radical, 18g/L of urea and 1.96g/L of creatinine, and the excrement has quite corrosiveness and particularly generates acid, ammonia and the like after glycolysis. Its polluting properties are high concentration of organic substances, malodours and pathogenic bacteria. Get rid of organic matter and solid in the excrement and urine, prevent that pathogenic bacteria and foul smell from diffusing outward is the key place of processing work, and the degree of difficulty and the complexity of handling excrement and urine are far higher than domestic sewage treatment, and these excrement and urine were regarded as fertilizer in the past mostly, and the application of current gravity bath lavatory for the solid content of excrement and urine is still less than 0.1%, has lost its original value of utilization, under the condition that the chemical fertilizer that can bring apparent economic benefits used in a large number, and the use amount of excrement and urine as fertilizer is withered day by day. If feces are treated as waste completely, the investment of the feces treatment plant is large (the investment is at least 500 ten thousand yuan calculated by a feces treatment plant with 100t/d treatment capacity at a constant price in 1992), the operation cost is high, and secondary pollution cannot be effectively controlled in the treatment process, so that the environmental pollution is caused. At present, biological septic tanks which are mostly adopted also obtain certain effect, but periodic dredging and deslagging are also needed, and the discharged water quality is further treated by a sewage treatment plant, so that the social cost is greatly increased.
