Description

Excrement and urine diversification treatment system and ecological treatment system

technical field

The invention relates to the technical field of feces treatment, in particular to a feces and urine diversity treatment system and an ecological treatment system.

Background technique

According to statistics, the annual excretion of feces per person is about 25-50L, which contains about 0.55kg of nitrogen, about 0.37kg of potassium, about 0.18kg of phosphorus, and high content of macromolecular substances such as cellulose, which cannot be directly used by crops; The annual urinary excretion is about 400-500L, including about 4kg of nitrogen, about 0.4kg of phosphorus, and about 0.9kg of potassium, and urine is easily absorbed by plants, and the amount of urine is much larger than that of feces.

According to the existing treatment methods of feces and urine, it is generally divided into dry toilets and water toilets. As we all know, the feces and urine in the dry toilet are stored together. Because the ammonia in the urine and the hydrogen sulfide in the feces will be mixed and fermented, the malodorous gas produced by the fermentation will make the dry toilet filled with irritating odors, which will attract mosquitoes and flies. Maggots breed and the sanitary conditions are poor, so dry toilets are increasingly being replaced. Water closets, also known as flush toilets, are flushed with water and discharged together with urine. Compared with dry toilets, water closets are more hygienic. However, the mixed discharge of manure, urine and water increases the amount of manure that needs to be treated. Even if it is sent to a sewage treatment plant for treatment, the treatment cost is staggering and a lot of water resources are wasted.

The feces can enter the feces storage tank 12 through the fecal hole, and the urine can enter the feces through the urination hole. to the urine storage tank 11.

Since urine contains a large amount of elements such as nitrogen, phosphorus and potassium, which are easily absorbed by plants, in order to realize the reuse of urine, the urine storage tank 11 and the ecological liquid storage tank 20 are connected. The ecological liquid storage tank 20 is mainly used for physical filtration and biological purification treatment of urine, so as to realize ecological treatment of urine, which is beneficial to subsequent utilization.

Since the vast majority of enteroviruses, enteropathogens, enteroparasites, and eggs are excreted from the intestines together with feces, in order to inhibit the survival of the above-mentioned enteroparasites and bacteria, reduce the risk of causing infection requires reprocessing of the feces. Therefore, the excrement storage tank 12 is connected to the excrement treatment system.

The manure treatment system includes an anaerobic tank 30 and an aeration sedimentation tank 40 . The fecal storage tank 12 is connected to the anaerobic tank 30 .
