Recycled water reusing processing system

Abstract

The invention discloses a recycled water reusing processing system. The system comprises a grating tank, an adjusting pond, a biological contact oxidation pond, a settlement pond, a water collecting pond, a sand filter, an active carbon filter and an ultraviolet light disinfecting pond which are sequentially communicated with one another along the flow direction of wastewater through a pipeline, wherein the grating tank is communicated with a wastewater drain pipe; and the water outlet of the ultraviolet light disinfecting pond is communicated with a recycled water reusing pipe network. The recycled water reusing processing system also comprises a sodium hypochlorite dosing device and a flocculant dosing device. A hair collector is arranged on the pipeline by which the water collecting pond and the sand filter are communicated. A pipeline mixture is arranged on a connection pipeline of the sand filter and the hair collector. Dosing pipelines are communicated with the pipeline mixture. A grating interval of the grating tank is 2mm, and the grating tank is a rotary mechanical grating cleaner. The recycled water reusing processing system has obvious effects that the system can completely process relatively clean wastewater, the reused water meets the reusing requirement, and the system is high in automation degree and can be controlled and managed automatically by a central controller, so that the shift of workers, the labor intensity and the like are reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a reclaimed water reuse treatment system. Background technique [0002] Reclaimed water refers to non-drinking water that can be reused in domestic, municipal and environmental areas after various drainages have been treated to meet the specified water quality standards. Recycling of reclaimed water is an important method of recycling sewage. It can not only reduce environmental pollution, but also increase the amount of available water resources, especially for clean washbasins and showers in daily life or office buildings. Drainage, condensate and other waste water are directly discharged into the sewer and mixed with other sewage for unified treatment instead of targeted separate treatment. This will not only increase the amount of sewage treatment and treatment time, but also these cleaner sewage do not need to be treated. Complicated treatment, complex treatment no...

Recycling of reclaimed water is an important method of recycling sewage. It can not only reduce environmental pollution, but also increase the amount of available water resources, especially for clean washbasins and showers in daily life or office buildings. Drainage, condensate and other waste water are directly discharged into the sewer and mixed with other sewage for unified treatment instead of targeted separate treatment. This will not only increase the amount of sewage treatment and treatment time, but also these cleaner sewage do not need to be treated. Complicated treatment, complex treatment not only wastes time and increases treatment costs, but also delays water recycling

Moreover, the traditional reclaimed water reuse system is aimed at the treatment and reuse of sewage from enterprises. It pays more attention to the sewage treatment of enterprises and units, and does not pay enough attention to the treatment of wastewater such as daily office buildings. The waste water is not the same, and the difference is relatively large, so it is not possible to copy the reclaimed water reuse system of enterprises and units, and the traditional sewage treatment system is not thorough enough, resulting in substandard discharge, and there is no reclaimed water reuse treatment for office buildings and other sewage system

[0003] The disadvantages of the prior art are: the existing reclaimed water reuse system is suitable for enterprises and factories, and is not suitable for the treatment of relatively clean wastewater such as office buildings, and the existing reclaimed water reuse system has a low degree of automation and is not suitable for sewage The processing is not thorough, the management is inconvenient, and the manual labor intensity is relatively high
