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 time that wastewater stays 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 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 waste water treatment device, which belongs to the technical field of sewage treatment, and comprises a treatment pool. A cover plate is fixedly installed on the top of the treatment pool, and the inside of the treatment pool is filled with activated sludge. For the pretreatment chamber and the reaction chamber, a water dividing mechanism is fixedly installed on one side of the partition. In the present invention, through the design of the spoiler mechanism, the residence time of the wastewater in the reaction chamber of the treatment pool can be effectively delayed under the abutment of multiple sets of spoilers, and the reaction distance of the reaction chamber of the treatment pool can be reduced. At the same time, the electric push rod Drive the extrusion rod to separate from the four spoilers attached to the bottom side. The spoiler that shrinks through reset will no longer disturb the waste water. On the one hand, it can improve the efficiency of waste water retention and reduce the large area occupied by the treatment tank. The inconvenience caused by site selection and installation, on the other hand, does not affect the rapid drainage treatment after wastewater treatment, improves the treatment efficiency, and meets the needs of use.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a 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 meet the ti...
