Fully-automatic middle-water deep purifying and regenerating water reuse apparatus and process

Abstract

The invention is a full-auto medium-water deep-purifying and regenerated water recovering device and technique, filtering the water to be processed by sand filtering tank, then filtering it by positive pressure biochemical water film filter, then sterilizing it in ozone generator, successively pumping the processed water by pump into aeration tank and synchronously irradiating the processed water by ultraviolet to be aerated and then be injected in the absorbing tank for absorption, and then injecting the absorbed water in the ultrafiltered water container; drawing and pressing the water in the ultrafiltering water container and then injecting in the nano filtering component for ion-level filtering, storing the produced pure water in the nano filtered water container to be used, and returning the strong water to the ultrafiltered water container for second treatment; the washing mode: opening the washing water inlet of the water distributor of the positive pressure biochemical film filter, and adding in pressure water to wash hollow external pressure ultrafilter film component, and then opening pressure sensing valve to discharge the sewage into the biochemical pond. If the device of the invention is linked with nano-filter water purifier to purify again, the water quality can reach drinking standard.

Description

technical field [0001] The invention relates to a water treatment device and a process, in particular to a reclaimed water treatment device and a process. Background technique [0002] With the increasing shortage of water resources, reclaimed water reuse technology has gradually received widespread attention. Especially in Beijing, where water resources are extremely scarce, the reuse of reclaimed water is extremely urgent in terms of long-term planning and the need for landscape water for the 2008 Environmental Protection Olympics. Nowadays, among the various technologies applied to reclaimed water treatment, biochemical, coagulation, dosing and sedimentation and membrane bioreactor are the main ones. The biochemical method is to use microorganisms to decompose the organic matter in the sewage. Obviously, the microorganisms themselves are organisms. According to the analysis of the raw water test results of a tap water factory No. 6, the water treated by the biochemical m...
