Abstract
The invention discloses an attapulgite-containing electroplating wastewater treatment agent. The treatment agent consists of the following components in parts by weight: 11-14 parts of attapulgite, 8-13 parts of ethyl acrylate, 5-7 parts of polyferric silicate, 3-4 parts of poly dimethyl diallyl ammonium chloride, 2-4 parts of sodium carbonate and 125-155 parts of water. The prepared treatment agent can be used for reducing the total chromium content, the total lead content and the total copper content in the electroplating wastewater and reducing the pollution of the electroplating wastewater.
Description
Technical field
The present invention relates to a kind of compound for treatment of electroplating wastes, particularly relate to a kind of compound for treatment of electroplating wastes that contains attapulgite.
Background technology
In relating to the workshop of plating, due to the clean metal surface, or electroplate liquid itself, and produced a large amount of electroplating wastewaters between douching wheels etc.In electroplating wastewater, composition is very complicated, may contain the heavy metal ion such as chromium, cadmium, nickel, copper, zinc, silver and prussiate etc., and some belongs to carcinogenic, teratogenesis, mutagenic highly toxic substance.How reducing their content in electroplating wastewater, is a field that is worth our research.Can reduce to a certain extent the content of mentioned component by chemical method or biological process, but effect not very obvious.
Summary of the invention
The technical problem solved: the problem of total chrome content, total lead content, total copper content overproof in electroplating wastewater.
Technical scheme: the invention discloses a kind of compound for treatment of electroplating wastes that contains attapulgite, treatment agent is comprised of according to weight ratio following composition: attapulgite is that 11～14 parts, ethyl propenoate are that 8～13 parts, ferric-polysilicate are that 5～7 parts, Poly Dimethyl Diallyl Ammonium Chloride are that 3～4 parts, sodium carbonate are 125～155 parts of 2～4 parts, water.In compound for treatment of electroplating wastes, attapulgite is preferably 14 parts; Ethyl propenoate is preferably 13 parts; Ferric-polysilicate is preferably 5 parts; Poly Dimethyl Diallyl Ammonium Chloride is preferably 4 parts.
The preparation method of compound for treatment of electroplating wastes is as follows: attapulgite is that 11～14kg, ethyl propenoate are that 8～13kg, ferric-polysilicate are that 5～7kg, Poly Dimethyl Diallyl Ammonium Chloride are that 3～4kg, sodium carbonate are 2～4kg, water 125～155kg.Under room temperature, that mentioned component is admixed together, stir, standby as compound for treatment of electroplating wastes.
Beneficial effect: after the compound for treatment of electroplating wastes that contains attapulgite is processed electroplating wastewater, total chrome content in electroplating wastewater is down to 0.66～0.87mg/L from 25mg/L, total lead content is down to 0.51～0.74mg/L from 14mg/L, and total copper content is down to 0.33～0.53mg/L from 27mg/L.
Embodiment
Embodiment 1
Attapulgite is that 14kg, ethyl propenoate are that 8kg, ferric-polysilicate are that 5kg, Poly Dimethyl Diallyl Ammonium Chloride are that 4kg, sodium carbonate are 3kg, water 125kg.Under room temperature, that mentioned component is admixed together, stir, standby as compound for treatment of electroplating wastes.
Embodiment 2
Attapulgite is that 11kg, ethyl propenoate are that 11kg, ferric-polysilicate are that 7kg, Poly Dimethyl Diallyl Ammonium Chloride are that 3kg, sodium carbonate are 4kg, water 140kg.Under room temperature, that mentioned component is admixed together, stir, standby as compound for treatment of electroplating wastes.
Embodiment 3
Attapulgite is that 12kg, ethyl propenoate are that 13kg, ferric-polysilicate are that 6kg, Poly Dimethyl Diallyl Ammonium Chloride are that 3kg, sodium carbonate are 2kg, water 155kg.Under room temperature, that mentioned component is admixed together, stir, standby as compound for treatment of electroplating wastes.
The electroplating wastewater processing test
The power taking waste electroplating, wherein total chrome content is 25mg/L, and total lead content is 14mg/L, and total copper content is 27mg/L.Electroplating wastewater is divided into to 3 groups, adds respectively the waste water conditioner of embodiment 1, embodiment 2, embodiment 3, addition is 1.4wt%.After interpolation, mixed solution is shaken up, shake up under rear normal temperature standing.Standing while no longer increasing to agglutinating matter, the upper strata stillness of night is separated with the lower floor agglutinating matter.The mensuration upper strata is total chrome content, total lead content, total copper content in the stillness of night.Concrete content sees the following form:
| Embodiment 1 | Embodiment 2 | Embodiment 3 | |
| Total chrome content (mg/L) | 0.66mg/L | 0.71mg/L | 0.87mg/L |
| Total lead content (mg/L) | 0.74mg/L | 0.51mg/L | 0.64mg/L |
| Total copper content (mg/L) | 0.46mg/L | 0.53mg/L | 0.33mg/L |
After processing through treatment agent of the present invention, the total chrome content in electroplating wastewater, total lead content, total copper content have all obtained significantly descending, and reduce the pollution to environment.
