Problems solved by technology

More and more projects have introduced MBR membrane technology with good treatment effect, stable water output and small footprint, but many engineering cases have not designed the membrane pool to play a systematic role, from water distribution, water output, sludge return, membrane cleaning, residual sludge There is no systematic integration in aspects such as emissions and equipment room layout

Abstract

The invention discloses a lateral water distribution MBR (Membrane Biological Reactor). The lateral water distribution MBR comprises a sewage treatment room and an equipment room which are adjacently arranged side by side, wherein the sewage treatment room comprises a first membrane tank section, a first feed water distribution channel, a middle internal reflux channel, a second membrane tank section and a second feed water distribution channel, the sewage treatment room is of a middle symmetrical structure and is divided into the two membrane tank sections by the middle internal reflux channel, the two outer sides of the two membrane tank sections are respectively provided with the feed water distribution channels, multiple groups of MBR membrane tanks are respectively arranged in the two membrane tank sections, and the feed water distribution channels can be used for simultaneously carrying out concentrated and uniform water distribution for each MBR membrane tank, so that the side channel water distribution is realized; the middle internal reflux channel can be used for simultaneously carrying out concentrated reflux and water yielding for the MBR membrane tanks. The lateral water distribution MBR is compact in structure, occupies a small area, can realize the concentrated water distribution, concentrated reflux and concentrated air purging for the MBR membrane tanks and has the advantages of small water head loss and low energy consumption.

Description

technical field [0001] The invention relates to a sewage treatment tank, in particular to a lateral water distribution MBR membrane biological reaction tank. Background technique [0002] In recent years, due to the improvement of environmental protection standards on the effluent indicators of sewage plants, and the need for regeneration and reuse of some sewage after treatment, it is difficult to meet the current effluent requirements by relying on the simple biological treatment process in the past. Therefore, a variety of sewage advanced treatment processes have emerged as the times require. [0003] The process principle of the sewage advanced treatment combination scheme is: to improve the quality of the treated effluent to meet the requirements of reclaimed water sources. The process selection is based on the water quality of the secondary treatment effluent and the requirements of the final treatment effluent. Among the effluent suspended solids (SS) of urban sewage...
