Embodiment Construction

[0013] The present invention will be further described below in conjunction with accompanying drawing:

[0014] When the amount of sewage is large, the liquid level controller 7 controls the sewage lifting pump 2 to start working, and the sewage in the sewage pool 1 enters the reaction column 3, enters the quartz sand, activated carbon and microfiltration column to further filter the water quality, mainly to remove the waste water. Fine suspended matter of organic matter; enter the calcium and magnesium resin column to absorb calcium and magnesium ions in the wastewater; the above-mentioned treated wastewater enters the hexavalent chromium resin column and the trivalent chromium resin column, and the pH of the comprehensive wastewater is 1.0-2.0 Between, under this acidity, the resin has a strong adsorption capacity for chromium; the treated wastewater enters the next group of acid-removing resin, which can adjust the pH value of the wastewater to between 3-13; after adjusting ...

Abstract

The invention discloses an integrated treating machine for electroplating sewage. The integrated treating machine comprises a sewage tank, a water pump, a reaction column, a sedimentation basin, a sludge-water separator and a clear water spilling device, wherein the sewage tank, the water pump, the reaction column, the sedimentation basin, the sludge-water separator and the clear water spilling device are successively connected via pipelines; and a liquid level controller is mounted in the sewage tank and is electrically connected with the water pump. The integrated treating machine provided by the invention is reasonable in structure and simpler than traditional sewage treating equipment, has the characteristics of small size, fast treating speed, capacity of carrying out intelligent operation according to a water volume and the like, integrates a plurality of functions and can be extensively applied to intensive primary physicochemical coagulation treatment of sewage and waste water.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an electroplating sewage treatment integrated machine. Background technique [0002] At present, electroplating wastewater is mainly composed of wastewater and waste liquid discharged from electroplating factories (or workshops), such as rinsing water for plated parts, waste bath liquid, equipment cooling water, and surface flushing water. Due to many types of plating, cumbersome process, complex water quality and difficult control of components, electroplating wastewater mainly contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver and cyanide, etc., which can generally be divided into three categories: One type is chromium-containing electroplating wastewater, and the concentration of chromium ions in this electroplating wastewater is relatively high; the second type is cyanide-containing electroplating wastewater, such that the concent...
