Problems solved by technology

However, this invention does not carry out further treatment of urine and feces, and the stool is not sterilized, so there is still a risk of polluting the environment; the urine is not filtered and purified, and it cannot be directly used after recycling

Embodiment 1

[0038] urine test 1

[0039] Urine is a normal human metabolite after being secreted by the kidneys. The urine of normal people is a transparent, almost amber liquid without bacterial pollution. Its pH range is 5.5-7.5, and its ingredients are water, urea, and chloride ions , sodium ions and other inorganic ions. In this series of experiments, a variety of methods were adopted to process the urine. The experimental design is as follows:

[0040] method serial number Type of test method one Magnesium Ammonium Phosphate Precipitation Method Method Two Activated carbon adsorption method method three RO membrane technology method Method Four RO membrane technology method + activated carbon adsorption method

[0041] 1. Magnesium ammonium phosphate precipitation method

[0042] 1.1 Raw water source and water quality

[0043] The water samples used in the test were the primary urine of different adult males. The primary urine samples ① ...

Embodiment 2

[0064] urine test 2

[0065] The urine is filtered through the ultrafiltration system, and the filtered clear liquid can meet the national water use standard, and finally realize the reuse of water resources. In this embodiment, the ultrafiltration system adopts the combination of RO membrane and activated carbon.

[0066] 1. Sample Collection

[0067] The primary urine of different adult males was collected, and the primary urine samples ① and ② were obtained after collection and storage respectively. Among them, the pH value of sample ① is 6.7, and the ammonia nitrogen content is 9100 mg / l; the pH value of sample ② is 6.6, and the ammonia nitrogen content is 8920 mg / l.

[0068] 2. Test method

[0069] Connect the original urine sample ① and sample ② to the activated carbon filter element through the self-priming pump device, and then enter the RO membrane for filtration to obtain the filtered clear liquid sample ① and sample ②.

[0070] 3. Test results

[0071]

Embodiment 3

[0073] Fecal Disposal Test

[0074] This test mainly focuses on the drying of feces, deodorization, sterilization, fermentation of beneficial microorganisms, etc., and screens the best drugs and methods for the harmlessness of feces. The experimental design is as follows:

[0075] Test purposes experiment method dry Desiccant, high temperature dehydration deodorant Deodorant sterilization UV sterilization, high temperature sterilization

[0076] experiment method:

[0077] 1. Screening of desiccant and determination of addition ratio

[0078] 1.1 Sample source

[0079] The feces used in the test were adult male excrement, which were collected and stored separately to obtain the original sample ① and sample ②.

[0080] Among them, the water content of sample ① is 79.3%; the water content of sample ② is 51.5%.

[0081] 1.2 Test steps and results

[0082] Mix sample ① and sample ② fully first to obtain comprehensive sample ③, the water c...

Abstract

The invention provides an ecological health system for separation of feces from urine as well as an application. A feces-urine shunt or a semi-shunt device is adopted by the system, and by combinationof a membrane treatment technology, biochemical and microbial treatment agents, sterilization\dying and other technical means, harmless treatment and resource utilization of human feces and urine arerealized. According to the system, water-saving and emission reduction can be realized, and domestic water, domestic wastewater and carbon emission are greatly reduced; urban and rural health can beimproved, the human feces and urine, are recycled on a large scale to replace chemical fertilizers and absorb feces, food safety and habitability of urban and rural communities can be improved, meanwhile, pollution of pathogenic microorganisms and nitrogen to human living environment can be fundamentally eliminated.

Description

technical field [0001] The invention belongs to the field of ecological sanitation and environmental protection, and in particular relates to a system for separating treatment and recycling of feces and urine. Background technique [0002] At present, there are two types of toilets most commonly used by urban and rural residents in my country, namely flush toilets and dry toilets. Flush toilets collect excrement in a centralized way through the pipe network, and then they are treated centrally by the sewage treatment plant; dry toilets use decentralized collection-yard composting to treat excrement. However, whether it is a flush toilet or a dry toilet, there are problems such as the need to flush with a large amount of water, the mixing of excreta with domestic water, rainwater, municipal water, and industrial wastewater is difficult and costly, and the breeding of mosquitoes pollutes the environment. In addition, for temporary or simple toilets in the field, rural areas, ...
