Abstract

The utility model discloses a cyanide-containing wastewater treatment system which comprises a first adjusting tank, a primary cyanide breaking tank, a secondary cyanide breaking tank, a broken cyanide sedimentation tank, a second adjusting tank, a primary flocculation tank, a secondary flocculation tank, a sedimentation tank, a UF (ultrafiltration) membrane coagulation suction filter and a discharge pool which are sequentially communicated through a pipeline, wherein a first pump is arranged on a pipeline between the first adjusting tank and the primary flocculation tank; and a second pump is arranged on a pipeline between the second adjusting tank and the primary flocculation tank. The cyanide-containing wastewater treatment system disclosed by the utility model realizes the advantages of simple treatment method and good cyanide content treatment efficiency by combining a chemical two-level cyanide breaking method and a physical-chemical sedimentation method.

Description

Cyanide-containing waste water treatment system
Technical field
The utility model relates to a kind of technical field of waste water processing, particularly cyanide-containing waste water treatment system.
Background technology
Cyanide wastewater is mainly derived from plating, the industries such as wet gold extraction, and due to the hypertoxicity of prussiate, cyanide wastewater must through processing, after reaching discharging standards, just can be discharged in environment.The facture of general cyanide wastewater is common alkaline chlorination process, electrolytic process, ion exchange method and activated carbon method etc.Though treatment process is relatively simple, processing efficiency is not high, can only process for containing the lower waste water of cyanogen amount.
The utility model content
The purpose of this utility model is to provide a kind of chemical two-stage broken cyanide that passes through in conjunction with the materialization coprecipitation mode in order to solve above-mentioned the deficiencies in the prior art, has realized treatment process simply and the cyanide-containing waste water treatment system of cyanogen content good treatment efficiency.
To achieve these goals, the cyanide-containing waste water treatment system that the utility model is designed, comprise the first equalizing tank, one-level broken cyanide groove, secondary broken cyanide groove, broken cyanide settling tank, the second equalizing tank, one-level flocculation basin, secondary flocculation basin, settling tank, the UF film coagulation suction filter that is communicated with successively by pipeline and discharge the pond, be provided with the first pump on the pipeline between the first equalizing tank and one-level broken cyanide groove, be provided with the second pump on the pipeline between the second equalizing tank and one-level flocculation basin.
Cyanide wastewater is through the first equalizing tank, then enter the reaction of two-stage broken cyanide groove by water pump lifting, add dioxide peroxide, alkali lye, sulfuric acid etc., PH, the redox potential of reacting by control, carry out broken cyanide again and process, the water outlet after processing enters the second equalizing tank, then adds the two-stage flocculation agent, prussiate precipitation is precipitated out with larger alumen ustum, sends into the discharging pond after through UF film coagulation suction filter and realize standard discharge.
As preferably: be provided with clorox or liquid caustic soda adds entrance on one-level broken cyanide groove, be provided with clorox and add entrance and PFS or PAM and add entrance on secondary broken cyanide groove.
As preferably: be provided with aeration stirrer on the second equalizing tank.
As preferably: be provided with active carbon powder and filter on UF film coagulation suction filter.
The cyanide-containing waste water treatment system that the utility model obtains in conjunction with the materialization coprecipitation mode, has been realized treatment process simply and the advantage of cyanogen content good treatment efficiency by the chemical two-stage broken cyanide.
