Wastewater treatment device

Abstract

The invention discloses a wastewater treatment device. The wastewater treatment device comprises a conditioning tank, a buffer tank, a reaction tank and a settling tank, wherein the reaction tank comprises a reaction tank casing and a silt deposition platform; the silt deposition platform is positioned at the bottom part of the interior of the reaction tank casing; a silt discharge pipe is arranged at the bottom part of the silt deposition platform; a water distribution pipe is arranged above the silt deposition platform; the water inlet end of the water distribution pipe penetrates through the side wall of the reaction tank casing and is communicated with the buffer tank; a plurality of water distribution holes are uniformly distributed in the upper part of the water distribution pipe; a biological reaction area is arranged above the water distribution pipe; a water drainage pipe is arranged at the side wall of the reaction tank casing above the biological reaction area; a circulating pipe is arranged on the water distribution pipe; the other end of the circulating pipe penetrates through the side wall of the reaction tank casing and is communicated with the upper part of the biological reaction area. The wastewater treatment device has the advantages that the structure is simple; the treatment scale and modification are facilitated, and a good self-control system and treatment effect are realized; by designing the porosity of the porous spherical outer casing, the porosity of a porous plastic ball, and the outer diameter of the porous spherical outer casing, the filtering effect of the biological reaction area is changed.

Description

technical field [0001] The invention relates to a waste water treatment device. Background technique [0002] A large amount of wastewater will be produced in industrial production, and the purification treatment of wastewater has attracted more and more attention from all walks of life. If it is not handled properly, it will cause a series of water pollution, the deterioration of the ecological environment, threats to human health and hinder the development of related industries. At present, countries around the world Especially in developing countries including China. Because conventional wastewater treatment methods are difficult to purify or cannot meet the technical and economic requirements of purification treatment, the purification treatment of industrial wastewater has become an urgent problem to be solved in the field of environmental protection technology at home and abroad. Contents of the invention [0003] According to the technical problem raised above, a w...
