Isolator for gaps of heavy metal

Abstract

The invention discloses an isolator for gaps of heavy metal, comprising an isolator shell, wherein a water inflow structure, a mixing chamber, a first reaction chamber, a second reaction chamber and a separation chamber which are successively communicated are arranged in the isolator shell from bottom to top. A water outlet corresponding to the lower part of the second reaction chamber is furtherprovided with a bevel board reaction zone in which a bevel board assembly for guiding is arranged. A bevel board is used for increasing the settling area under the limited settling volume, thereby enhancing the settling effect.

Description

technical field [0001] The invention belongs to waste water purification treatment technology, in particular to a heavy metal gap separator for treating waste water containing toxic substances such as chromium, cadmium and cyanide. Background technique [0002] The industrial wastewater discharged from mining factories, electroplating factories and other industries contains toxic substances such as acid, alkali and cyanide, as well as heavy metals such as chromium, cadmium, copper and zinc. Traditional multi-stage treatment methods are adopted, such as three-step method: neutralization reaction, Precipitation and filtration, although the effect is better, but the device used in this method not only occupies a large area, consumes a lot of energy, but also has complicated operation and operation management. Although the primary treatment device that has been widely used in production occupies a small area, its disadvantages are: the treatment method is single and the function...

[0002] The industrial wastewater discharged from mining factories, electroplating factories and other industries contains toxic substances such as acid, alkali and cyanide, as well as heavy metals such as chromium, cadmium, copper and zinc. Traditional multi-stage treatment methods are adopted, such as three-step method: neutralization reaction, Sedimentation and filtration, although the effect is good, but the device used in this method not only occupies a large area, but also consumes a lot of energy, and the operation and operation management are complicated

Although the primary treatment device that has been widely used in production occupies a small area, its disadvantages are: the treatment method is single and the function is not perfect; the conventional sedimentation is used for sedimentation, and the volume of the sedimentation tank is limited, resulting in suspended solids and clear water. Incomplete liquid separation increases the difficulty of subsequent filtration; due to its own structural defects, sludge deposition is prone to occur
