Description

STP ecosystem based on source separation

Technical Field

The utility model relates to a domestic waste handles technical field, concretely relates to STP ecosystem based on source separation.

Background

Excrement and urine are once an important source of agricultural fertilizers in China. In recent years, as water flushing toilets are gradually popularized, a large amount of water resources are used for flushing the toilets, the water consumption for flushing the toilets in urban families accounts for 10% -30% of the total water consumption for flushing the toilets in the urban areas, and the water consumption for flushing the toilets in public places accounts for almost 90% of the total water consumption. On one hand, the transportation and management cost is multiplied, farmers are not capable of bearing expensive operation cost, and the original utilization value is lost; on the other hand, the popularization of water-flushed toilets is a great obstacle to saving water resources due to the lack of fresh water resources at present.

The septic tank is used as a simple and common waste water collecting facility, and mainly reduces surface water and underground water environment pollution caused by direct discharge of domestic waste water, and needs to be cleaned regularly after long-term use. The septic tank wastewater contains a large amount of organic matters, nitrogen, phosphorus and other substances, and if the septic tank wastewater is directly discharged to an earth surface basin, the river water body is blackened and smelled, so that the section of the septic tank wastewater seriously exceeds the standard.

The ammonia, hydrogen sulfide, mercaptan, thioether and other harmful gases with malodorous components contained in the wastewater can cause serious pollution to water bodies. Especially, the excrement of patients and various parasitic ova, pathogenic bacteria and viruses contained in the excrement are directly discharged into water, immeasurable disasters can be brought to production and life of people, a large amount of organic matters contained in the excrement wastewater provide places for reproduction and breeding of mosquitoes, flies, fleas and mice, the organic matters become vectors of infectious diseases, and a large amount of toxic and harmful malodorous gases can be generated after the organic matters are decomposed. And soil, water and atmosphere are seriously polluted, a biological community is influenced, the ecological environment is deteriorated, and the health of people is seriously influenced.

The wastewater collected by the septic tank is different from general domestic wastewater, and the septic tank wastewater refers to the general term of urine, all excrement or residual excrement and wastewater generated in the flushing process. The main pollutant indexes in the wastewater are CODcr, BOD 5, SS, NH 3-N, TN, TP, fecal coliform bacteria, viruses and the like, the pollution indexes are far larger than those of common domestic wastewater, and are several times or even more than ten times of that of the common domestic wastewater, and the treatment and recycling process is complex.

The excrement wastewater is only one part of domestic sewage and is the most important part, the domestic sewage is generated during vegetable washing, bowl brushing, clothes washing and bathing, and how to reasonably and effectively treat the domestic sewage in villages and towns is an urgent matter.

At present, no sewage discharge system can realize the full sewage discharge treatment of a domestic pollution source without polluting the environment while meeting the requirement of saving water resources.
