Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the treatment effect of activated sludge is determined by the residence time of wastewater in the reaction tank, it is generally necessary to build a longer reaction tank or ring to meet the time required for wastewater reaction, which leads to the fact that the reaction tank generally occupies an area The area is larger, which increases the difficulty of the assembly site selection of the treatment equipment and the subsequent construction, and a circulating wastewater treatment device is proposed

Embodiment approach

[0043] The implementation method is as follows: when the waste water to be treated enters the pretreatment chamber on the side of the treatment pool through the drainage equipment, the original activated sludge in the pretreatment chamber can reduce the concentration of the waste water and carry out sand removal and precipitation. When the treatment chamber is fed with water again, it enters the reaction chamber on the side of the treatment pool. At this time, the water entering the reaction chamber can abut and contact the surfaces of the spoilers on both sides under the action of the abutment and diversion of the spoiler on the front side, and Under the abutment effect of the lateral spoilers on both sides, the flow velocity of the waste water at the rear side of the transverse spoiler slows down after continuous diversion to the outside of the spoiler, and the waste water after the flow velocity slows down can adhere to the surface of the rear inflatable cover. The activated...

Abstract

The invention discloses a circulating type wastewater treatment device, and belongs to the technical field of sewage treatment, the circulating type wastewater treatment device comprises a treatment tank, the top of the treatment tank is fixedly provided with a cover plate, the treatment tank is filled with activated sludge, the inner cavity of the treatment tank is divided into a pretreatment cavity and a reaction cavity through a partition plate, and one side of the partition plate is fixedly provided with a water distribution mechanism. According to the invention, through the designed spoiler mechanism, under the abutting action of a plurality of groups of spoilers, the retention time of wastewater in the inner cavity of the reaction cavity of the treatment tank can be effectively delayed, the reaction distance of the reaction cavity of the treatment tank is reduced, and meanwhile, an electric push rod drives an extrusion rod to be separated from the four spoilers attached to the bottom side; the repositioned and contracted spoiler does not generate a spoiler effect on the wastewater any more, so that on one hand, the wastewater retention efficiency can be improved, the inconvenience caused by relatively large occupied area of the treatment tank to site selection and installation is reduced, and on the other hand, the rapid drainage treatment after the wastewater treatment is not influenced, the treatment efficiency is improved, and the use requirements are met.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a circulating waste water treatment device. Background technique [0002] The activated sludge method is an aerobic biological treatment method for sewage. Today, the activated sludge method and its derivative improvement process are the most widely used methods for treating urban sewage. It can remove dissolved and colloidal biodegradable organic matter, suspended solids and other substances that can be adsorbed by activated sludge from sewage, and can also remove part of phosphorus and nitrogen, which are suspended in water for wastewater biological treatment. A general term for various methods of microorganisms. [0003] When the existing activated sludge method treats wastewater, since the residence time of the wastewater in the reaction tank determines the treatment effect of the activated sludge, it is generally necessary to build a longer reaction tank or ring to...
