Abstract

The present invention includes increases intermediate water producing factory, intermediate water supplying pipeline and domestic waste water recovering pipeline on the basis of available water supply pipeline; re-constructing city excrement draining and recovering pipeline and re-builds the city sewage processing factory into organic fertilizer plant. The city domestic sewage is drained in new pipeline for recovery and processing into intermediate water for secondary use in flushing toilet and other proper purpose. The city excrement is recovered and treated to produce marsh gas and organic fertilizer.

Description

Technical field [0001] The invention relates to the supply and discharge of urban domestic water, especially the supply and discharge of potable water and non-drinkable water, so that domestic waste water can be reused to achieve the purpose of water saving and organic fertilizer reuse. drainage system. Background technique [0002] The current supply of urban water is the combined supply of drinking water and non-drinking water that has been used for many years, and the method of one-time discharge. The resulting result is that domestic wastewater is discharged together with fecal sewage, causing a large amount of domestic wastewater to be lost in vain, which is not only a waste of water resources, but also increases the pressure on urban sewage treatment; Floating population, a large amount of excrement every day puts great pressure on urban sewage treatment. However, the vast rural areas of our country are facing a serious shortage of organic fertilizers, and they rely ...
