Recycling collection and utilization system for excrements in toilets of urban and rural areas

Abstract

The invention relates to a recycling collection and utilization system for excrements in toilets of urban and rural area. The recycling collection and utilization system is characterized by comprisinga toilet utensil realizing water-free biological decomposition of feces, a pipeline, a feces collecting pond and a urine collecting pond, wherein the toilet utensil realizing water-free biological decomposition of feces comprises a toilet utensil shell, a flushing-free urine isolating device, a stirring thrust pump and a microbial flora ecological degradation device, the microbial flora ecological degradation device is arranged at the inner side of the toilet utensil shell, a discharge hole is arranged at the bottom of the microbial flora ecological degradation device, the discharge hole is connected with the stirring thrust pump, the stirring thrust pump communicates with a collecting branch pipeline, the flushing-free urine isolating device is arranged at the inner side of the toilet utensil shell, the flushing-free urine isolating device communicates with the collecting branch pipeline, and the collecting branch pipeline is connected with the feces collecting pond and the urine collecting pond through a conveying main pipeline. The recycling collection and utilization system for excrements in toilets of urban and rural area has the beneficial effects that abundant domestic water can be saved, the collected feces do not enter an urban and rural pipe network, and thus the pollution caused to the river environment and surface water by the feces is completely eradicated; and the collected feces after ecological treatment is adopted as the basic raw material of organic fertilizers.

Description

technical field [0001] The invention belongs to the technical fields of environmental protection and agricultural ecology, and in particular relates to a resource collection and utilization system for urban and rural toilet excrement. Background technique [0002] At present, the feces in urban toilets are generally treated in septic tanks and discharged directly into urban sewers, and then transported to sewage treatment plants for concentration and discharged into rivers and lakes. According to statistics, the average excrement per person is 145g each time, and 4-12 liters of tap water is needed for flushing. Every year domestic urban toilets consume 5-10 billion tons of tap water, resulting in a huge waste of water resources. [0003] The current water-flush toilets that are generally applicable have serious disadvantages: first, a large amount of water resources are wasted; second, larger septic tanks are required to accommodate; third, septic tanks are difficult to clea...

AI Technical Summary

Problems solved by technology

Problems existing in the current existing technology: First, the structure of the feces and urine separation toilet is complicated; second, the ecological treatment of feces and urine still stays at the source before entering the sewage treatment plant, and post-processing equipment takes up a large area and costs high As well as problems such as huge and complex processing equipment, it is difficult to promote the recycling of human feces and urine resources
