Embodiment Construction

[0017] see figure 1 , figure 2 , The reactor of the sewage treatment reactor includes a tank body 1, a water inlet pipe 2, a connecting pipe 3, an outlet pipe 4, a sludge discharge pipe 5 and an aeration device 6. Four partition walls 7 are vertically arranged in the pool body 1, and the pool body 1 is divided into four grids, which are respectively used as four biological reaction pools 8, and suspended fillers 9 are provided in each pool (specifically, semi-soft composite fillers are used); The water inlet pipe 2 is set on the top of the pool body 1 and communicates with the water inlet of each grid bioreactor 8 respectively, and the connection pipes 3 between each grid bioreactor tanks are connected in turn, and the four grid bioreactors are respectively provided with independent water outlet pipes 4 . The inlet and outlet pipes and the connecting pipes of each pool are provided with electromagnetic valves 12, which can realize the conversion of continuous flow and inter...

Abstract

The invention discloses a sewage treatment reactor for alternately operating an intermittent flow and a continuous flow. The reactor comprises a tank body, an inlet / outlet water pipe, a connecting pipe, an eration system, and the like. Separation walls are vertically arranged in the biological treatment tank body and divide the biological treatment tank body into at least four grids which are respectively used as a biological reaction tank; each of the other tank is provided with an independent inlet / outlet water system and a connecting pipe which is arranged between two adjacent tanks; each tank is provided with suspension stuffing; and the bottom of each tank is provided with a microporous aeration device and a sludge discharge pipe. The invention has the advantages of flexible operation modes, high treatment efficiency, strong shockproof loading capacity, lower operation energy consumption, small remaining sludge amount, short process, small floor area, little investment, convenient management, and the like.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a sewage treatment reactor with alternate operation of intermittent flow and continuous flow. Background technique [0002] Conventional urban sewage treatment facilities require large investment, high operating costs, and complex operation and management, making it difficult to promote them in small towns. In recent years, the reactor technology for small town sewage treatment has developed rapidly, such as CN2811278Y "six-dimensional three-phase biological treatment process device", CN1552644 "a small town sewage treatment process" and CN2780751 "baffled wetland" published in Chinese patents Filter + lateral subsurface flow wetland bed sewage treatment system" and so on, are continuous flow bioreactors, which are different from the continuous flow and sequence batch operation modes of this reactor. In order to achieve higher tr...
