A water resource recycling system

Abstract

The invention relates to a cyclic utilization system of water resources, comprising a bathroom sewer pipe, a washing machine sewer pipe and a kitchen sewer pipe, wherein an oil-water separator is arranged between the kitchen sewer pipe and the sewer main pipe, the sewer main pipe inlet is also communicated with an overflow outlet of a toilet bowl, and the inlet of the toilet bowl is communicated with the washing basin sewer pipe; the water outlet of the main sewage pipe is communicated with the sedimentation tank, and the sedimentation treatment tank is sequentially communicated with an anaerobic treatment tank, an aerobic treatment tank, an adsorption treatment tank, a neutralization treatment tank, a first biological treatment tank, a second biological treatment tank, a third biologicaltreatment tank, a fourth biological treatment tank and a disinfection treatment tank; and the water outlet of the disinfection treatment tank is communicated with a recycling water storage tank. The invention improves the efficiency of water saving, has strong practicability and is worth popularizing.

Description

technical field [0001] The invention belongs to the technical field of water saving, and in particular relates to a water resource recycling system. Background technique [0002] Today's world is facing three major problems of population, resources and environment, and water resources are an irreplaceable and important resource among all kinds of resources. Water resources are closely related to the environment, and are also indirectly related to population. Therefore, the issue of water resources has become one of the most important issues attracting worldwide attention. [0003] China is a country with severe drought and water shortage. The total amount of fresh water resources is 2,800 billion cubic meters, accounting for 6% of global water resources, ranking fourth in the world after Brazil, Russia and Canada, but the per capita is only 2,200 cubic meters, which is only 1 / 4 of the world's average level. 1 / 5 of the United States, ranking 121st in the world, is one of th...

Problems solved by technology

The increasingly serious water pollution not only reduces the use function of water bodies, but also further exacerbates the contradiction of water resource shortage

[0004] In recent years, the water resource recycling system has provided a new idea for water saving, but the current water recycling rate in China is less than 1 / 3 of that in developed countries, and most of the water resource recycling systems are aimed at industrial fields and cities In terms of management work, the water resource recycling system for rural areas and small towns is almost blank, and the existing water resource recycling system has a single function, and does not have the functions of multi-layer purification and multiple reuse
