Description
Technical Field
The utility model relates to a waste recycling technology field especially indicates a polylactic acid membrane packing type ultra-temperature compost formula flushing-free toilet.
background
china is a country with serious drought and water shortage. The total amount of fresh water resources is 28000 billion cubic meters, accounts for 6 percent of the water resources of the world, is second only to brazil, russia and canada, and is in the fourth world, but people are 2300 cubic meters, which is only 1/4 of the world average level and 1/5 of the united states, and in 121 ranks in the world, the fresh water resources are one of the 13 countries with the most water resources of the world. High water consumption is also a characteristic of most domestic water closets. According to investigation, the water consumption of the household water closet can account for about 60 percent of the daily water consumption of some households. Unlike many developed countries which mainly use reclaimed water to flush toilets, domestic toilet flushing water is mainly clean tap water. Therefore, a great amount of precious water resources are wasted after only exerting the minimum function every year in China. According to data statistics, only one toilet is flushed, and about 100 billions of cubic meters of tap water is consumed in China every year, which is equivalent to the annual tap water consumption of 50 domestic medium-sized cities. With the development of science and technology and the improvement of the national development level, the policy of environmental protection is more and more emphasized, and the conservation of water resource is more and more emphasized. The large amount of water resources consumed by flushing every year are prohibited to attract a great deal of attention of people. The development of the waterless toilet flushing also increasingly arouses the thinking of people, and the requirements of high-end ecological places are added, so that the waterless toilet is a necessary material condition in the life of people in the future.
on the other hand, according to the united nations data, toilets used by 21 hundred million people worldwide discharge sewage directly or fail to be connected to septic tanks capable of safely cleaning excrement. Therefore, 2 hundred million tons of human excrement can not be collected and treated every year, so that soil and water sources are seriously polluted and the health of human beings is threatened. The working principle of the traditional septic tank is roughly five steps: the method has the advantages of high cost, need of connecting an urban sewer pipe network, and capability of directly discharging the excrement and urine into a natural water body without treatment conditions in many remote mountain areas. And the urban sewer is often blocked due to design defects or human factors, so that great troubles are brought to the normal life of people. People in remote areas or developed cities desire a convenient, rapid, energy-saving, environment-friendly, low-cost and non-blocking excrement and urine treatment process to replace the traditional septic tank system.
