To sum up, the embodiment of the utility model provides a source separation ecological toilet, lies in excrement and urine, urine from source separation processing (source separation) meaning:

modern civilization of human beings is rapidly developed, and among them, the water-washed closestool is regarded as a modern civilization product which draws luxury. Unfortunately, flushing toilets "sanitarily and ecologically" does not return the original nutritional residue from the land, namely the manure, to the land. While enjoying various modern civilization achievements to bring various conveniences and comfortableness to us, the ecological environment in which all things depend on living is increasingly deteriorated, and resources are in short supply or even are almost exhausted. Two factors that can be determined exist in the resource environment enough to cause the death of human beings in hundreds of years, namely climate change and phosphorus crisis. The former has attracted high importance to the international and domestic society, and the countries are adopting necessary control and remedial measures. However, the latter is currently the situation of international importance and national sitting. In fact, the most effective means for preventing the phosphorus crisis is the habit of returning feces and urine to the field formed by the old ancestors in long-term practice. The traditional dry latrine and excrement return habit in rural areas is only 'ecological but not sanitary', the ecological effect is essential, and the insanitary dregs can be perfectly solved by the technology. Municipal drainage networks were sourced in europe as the industrial revolution in the 19 th century, when mainly based on hygienic considerations to reduce diseases (e.g. cholera, dysentery, etc.) transmitted through drinking water. Since then, toilets and centralized plumbing systems symbolizing "modern civilization" have continued to date as a common drainage model for today's urban development. However, the modern civilization which rushes over is reverse in the situation that the sustainable development and the ecological civilization construction are emphasized nowadays, because the living habit of the ancestor that food comes from the land and excrement returns to the land is exactly a simple ecological cycle at present, and is known as the original ecological civilization by people who know at home and abroad. The current mainstream centralized drainage system aggravates water crisis, phosphorus crisis and even energy crisis.

Meanwhile, the modern civilization mode also increases environmental risks, and increases infrastructure investment, maintenance cost and operation energy consumption. Researches show that the traditional sewage treatment mode has the operation energy consumption as high as 50-100kW & h/(man & a), which shows that the modern civilization is an unsustainable life style. In this regard, the centralized drainage mode under "modern civilization" is increasingly questioned by researchers in terms of sustainability and ecological benefits, so that the distributed ecological drainage mode mainly based on source separation, namely, the separation of excrement from domestic drainage at the source, is regained. The original ecological civilization habit of returning the feces and the urine to the field can be recovered to the maximum extent, water resources can be saved, the water pollution condition can be relieved, the sewage treatment degree can be reduced, and carbon emission reduction can be realized.

The direct ecological environment effect generated by the source separation can effectively intercept and separate nutrient elements such as phosphorus and the like contained in the excrement and urine, and the nutrient elements can be returned to the 'mother' land as much as possible. In addition, the direct ecological environment effect also comprises the aspects of water resource saving, water pollution reduction and the like. The source separation creates an indirect environmental benefit in reducing the extent of wastewater treatment and the resulting energy consumption reduction and carbon emission reduction problems.

The main purpose of source separation is to realize harmless treatment of excrement and urine and the original ecological regression of useful resources such as nitrogen, phosphorus, potassium and the like. Under the condition that phosphorite resources are increasingly deficient, the function and purpose of source separation are obvious. Authoritative research shows that if the annual growth demand of 3% of chemical fertilizers for global agricultural production is maintained, the current global residual phosphorite resources cannot be expected to be used for human for 100 years, and the global residual phosphorite resources are only enough to be maintained for about 50 years at most. Source separation another significant ecological environmental effect is the saving of water resources, the main saving being toilet flushing water. Modern urban civil buildings are generally few or even have no reclaimed water systems, and toilet flushing water, namely municipal tap water, accounts for about 30% of the total household water consumption. The water consumption of the designed closestool 1 is 3 percent of that of the traditional closestool and 5 percent of that of the modern water-saving closestool, and the water consumption is about 300ML every time. If the urine and the excrement can be separated and independently recovered in a source separation mode, more than 80% of nitrogen and 50% of phosphorus in the domestic sewage are reduced, the nitrogen and phosphorus treatment pressure of a sewage treatment plant can be greatly reduced, and the probability of occurrence of black and odorous water can be reduced even if non-intercepting sewage directly enters a water body and corresponding nitrogen and phosphorus loads can be reduced. If the source separation plan is implemented, the excrement and the urine are not mixed into the domestic sewage any more, so that the sewage becomes clean at once and actually becomes grey water (namely high-quality impurity drainage). If the excrement and urine are separated by source separation and are treated separately, the loads of nitrogen, phosphorus and organic matters in the sewage are reduced by 97%, 90% and 59% respectively. That is to say, the three-stage sewage treatment process is redundant after the manure and urine source separation is carried out, only the first-stage treatment and even the wetland treatment are used, the problem that nearly 40 percent of organic matters remain in the grey water can be solved, and the removal of nitrogen and phosphorus is not necessary at all. On the other hand, the energy consumption and carbon emission of sewage treatment can be reduced. The source separation is based on the five thousand years original ecological civilization habit of Chinese nation and is the modern explanation of the simple circulation of the nutrients of returning the excrement to the field. The ecological environment effect brought by the source separation has obvious effect, can not only recover the agricultural culture civilization to the maximum extent and inhibit the shortage speed of the non-renewable phosphorus resources to the maximum extent, but also can save water resources and effectively inhibit the water pollution condition. In a word, the separation of the excrement and urine source can also greatly reduce the sewage treatment degree, effectively reduce the sewage treatment energy consumption and realize carbon emission reduction.

Meaning of separating organic waste from source (source separation) for on-site treatment:

the organic garbage refers to the decomposable organic substance part in daily life garbage. The organic garbage comprises food residue, vegetable root, vegetable leaf, animal hoof, horn, melon peel, fruit bits, eggshell, fish scale, eggshell, hair, plant branch, leaf, weed, animal body, livestock feces, etc. Accounting for more than 50 percent of the total amount of the garbage. Organic waste has two major sources: garden garbage and kitchen garbage. The organic garbage has the characteristics of easy decay, low heat value, rich organic matter content and the like, and if the organic garbage is not separated from a source, conventional landfill and incineration are difficult to properly treat, and secondary pollution can be caused during transportation. If 50% of organic garbage is separated from the source and is treated on the spot, 30% of the garbage which can be recycled is recycled, and only 20% of the garbage is finally left to be buried, so that a large amount of land is saved, and the risk of environmental pollution caused by seepage during the landfill is avoided. Organic garbage is easy to rot and sometimes contains pathogenic microorganisms. The organic waste has great harmfulness in the aspects of hygiene and epidemiology, but the organic waste is rich in nitrogen, phosphorus, potassium and other components, so that the organic waste can kill pathogenic microorganisms, various agricultural pests and weed seeds, can also decompose and decompose organic waste, and is easy to absorb and utilize by plants by adopting a high-temperature composting method for treatment.
