Environment-friendly system for excrement-water/urine-water separation and collection

Abstract

The invention relates to the technical field of excrement-water separation, in particular to an environment-friendly toilet apparatus for excrement-water/urine-water separation and collection. The environment-friendly toilet apparatus comprises a water tank and a body. A three-way valve is connected to the bottom of the body and is connected with two connecting pipes which are independent; one connecting pipe is a blow-down pipe communicated with an excrement collection tank; the other connecting pipe is a drain pipe communicated with the blow-down pipe. The environment-friendly toilet apparatus has the advantages that excrement and water are separated for convenience of collection, active components are never diluted by the water, and organic fertilizer can be greatly collected for free; the organic fertilizer can be transported for farmland irrigation and restoration of the natural circulation of materials; methane gas, deep-processed fertilizer and proteins can be produced; fouling odor can be isolated effectively, a trap is omitted, flushing water is little, and water resources are saved; excrement and flushing water are separated and are discharged to urban sewers, low pollution is caused to rivers and lakes, underground water and soil are protected, cleaning work of septic tanks is reduced, and urban sanitation cost is reduced; the environment-friendly toilet apparatus is good in operation stability, simple in structure, low in cost and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of excrement-water separation, in particular to an environmental protection system for separating and collecting excrement-water and urine-water. Background technique [0002] The known toilets all have sinkholes. When flushing, the water needs to flush the excrement through the sinkhole before entering the sewage pipe, which consumes a large amount of water; the excrement is not recovered and enters the groundwater system, or flows into the sewage pipe from the city. Rivers and lakes cause pollution; if packet collection is used, the amount of flushing water will be large, making the excrement ineffective as fertilizer and of no recycling value; especially the excrement cannot be returned to the field, which increases the cost of urban sanitation, interrupts the cycle of natural exchange of materials, and causes organic pollution. A large amount of fertilizer is wasted; and the excrement mixed with water wi...
