According to the wastewater treating agent for electroplating, raw materials are easy to obtain, the wastewater treating agent is easy to obtain, low in cost, high in comprehensive electroplating wastewater treating capability, convenient to use and capable of increasing the settling speed of heavy metal ions, and the heavy metal ion removal rate reaches 99%.
Description
Technical field
The present invention relates to a kind of plating waste water treating agent.
Technical background
The source of electroplating wastewater is generally: (1) plating piece rinse water；(2) spent plating bath；(3) other waste water, including washing away car
Between ground, scrub pole plate wash water, ventilation installation's condensed water, and due to coating bath seepage or operation management improper cause " run,
Emit, drip, leak " various tank liquors and draining；(4) component cooling water, cooling water in addition to temperature rising, is not subject in use
To pollution.Process conditions, produce load, operation management and water use model that the water quality of electroplating wastewater, the water yield are produced with plating etc.
Factor is relevant.The water quality of electroplating wastewater is complicated, and composition is wayward, wherein contains the heavy metals such as chromium, cadmium, nickel, copper, use, gold, silver
Ion and cyanide etc., some belong to carcinogenic, teratogenesis, mutagenic extremely toxic substance.
The method for comprehensively treating waste liquid that electroplating wastewater adopts at present has a lot, such as chemical method, ion exchange, electrodialysis
Method, electrolysis etc., wherein chemical method are more common method, and it is to add reducing agent in waste water (as ferrous sulfate, sulfurous acid
Sodium, iron powder etc.), heavy metal ion is reduced, adds waste water treating agent sodium hydroxide, the ph value of adjustment waste water, fractional precipitation gives up
Heavy metal ion in water, finally also needs the supernatant ph value after precipitation by acid adding adjustment could discharge.Using so
Waste water treating agent process electroplating wastewater, consumption is big, makes electroplating waste processing process long flow path, takes up an area many, and greatly, the energy disappears for investment
Consumption is big, and operational management difficulty is big, and labor strength is big, and operating cost is high, can't ensure that wastewater treatment is stably run.
In view of above-mentioned defect, the design people, actively research and innovation in addition, to founding a kind of plating wastewater treatment
Agent is so as to more the value in industry.
Content of the invention
For solving above-mentioned technical problem, it is an object of the invention to provide a kind of plating waste water treating agent.
Technical scheme is as follows:
A kind of plating waste water treating agent it is characterised in that include following parts by weight each component, reducing agent, 20～

Part；Graphene, 5～10 parts；Starch xanthate, 5～10 parts；Adsorbing material, 30～40 parts；Aluminium salt, 5～10 parts.
Further, described reducing agent is sodium sulfide, ferrous sulfate, the mixture of sodium pyrosulfite.
Further, described alkaline matter be sodium hydroxide, potassium hydroxide, any one or its mixing in calcium hydroxide
Thing.
Further, described metallic ion trapping agent is disodiumedetate.
Further, described adsorbing material is is one of activated carbon, bentonite, kieselguhr, Kaolin.
Further, described aluminium salt is one of aluminum sulfate, aluminum chloride, aluminium oxide.
By such scheme, the present invention at least has the advantage that
Compound for treatment of electroplating wastes raw material of the present invention is easy to get, and is easily obtained, low cost, and the ability processing electroplating comprehensive waste water is strong
And easy to use, the sedimentation velocity of heavy metal ion can be accelerated, the clearance of heavy metal ion reaches 99%.
