Description

A kind of integrative electroplating waste treatment agent

Technical field

The invention belongs to field of Environment Protection, relate to a kind of waste water conditioner, relate to specifically a kind of integrative electroplating waste treatment agent.

Background technology

Integrative electroplating waste is the various waste water of discharging at plating production process.Integrative electroplating waste is generally containing chromium plating wastewater, nickel-plating waste water, copper plating wastewater, zinc-plated waste water, acidic and alkaline waste water etc., its pollutant load is high and composition is diversified, the pollution causing is roughly: the pollution of chemical toxicant, the pollution of organic aerobic material, the pollution of inoganic solids suspended substance and acid, alkali, heat etc., the pollution such as coloured, foam, oils.

Integrative electroplating waste complicated component, treatment technology is also varied, currently used treatment process mainly contains chemical method, physico-chemical process and biological process etc.

Chemical method adds chemical reagent exactly, by chemical reaction, makes pollutent in electroplating wastewater become innoxious substance or be easy to the material separated with water, then the treatment process of further removing from electroplating wastewater.Chemical method mainly comprises: chemical precipitation method, chemical oxidization method, chemical reduction method, neutralisation etc.The advantages such as less investment, treatment unit are simple, processing cost is lower although this method has, installation and maintenance and processing ease, exist that processing efficiency is low, effluent quality is poor, can not recycle and produce the shortcomings such as sludge quantity is large.

Physico-chemical process mainly comprises: ion exchange method, membrane separation process, evaporation concentration method, absorption method etc.Ion exchange method have convenient management, cost of investment low, easily be automated, separation efficiency is high, advanced treatment is effective, water outlet can reuse etc. advantage, chromium plating, nickel plating and plating precious metal have been widely used in as in gold and silver wastewater treatment, but high owing to existing processing cost, regenerated liquid is difficult to the problems such as recycling, and effect is also not obvious.Membrane separation technique is mainly micro-filtration, ultrafiltration and reverse osmosis etc.But adopt membrane separation technique to exist cost of investment higher, membrane element easily damages and causes membrane flux to decline rapidly, regeneration, replacing diaphragm complicated operation, inconvenience is grasped, the shortcomings such as the permanent stability deficiency of system.Evaporation concentration method is a good method for traditional flucculation process, because it does not need to add medicament, tasteless, without gas, also without Toxic, discharges.Evaporation concentration method can not only reduce waste liquid volume, and distilled water can be recycled, and concentrated solution can be replied to use or go and be burned.But exist, power consumption is large, process cost is high, and the problems such as impurities removal, are difficult to promote the use of.Absorption method is to utilize the method for the physical structure heavy-metal ion removal of sorbent material.Gac is one of modal sorbent material of processing electroplated heavy metals waste water.Gac equipment is simple, but regeneration of activated carbon is difficult, and poor processing effect, and after processing, water quality is difficult to reuse.

The mechanism of biological process processing electroplating wastewater is the relation of alternate, symbiosis, in microbial growth, reproductive process, can produce a certain amount of meta-bolites, and this class biological mass-energy changes the heavy metal ion valence state in waste water.Microorganism species itself also has stronger biofloculation, electrostatic adsorption simultaneously, and adsorbing metal ions, makes it after solid-liquid separation, enter bacterium mud cake, discharged wastewater met the national standard or reuse.Microbial method has the advantages such as efficiency is high, selectivity is strong, loading capacity is large, but have at present that reaction efficiency is not high, substratum consumption is large, processing cost is high, the remnants biology in water outlet can also continue breeding, can not direct reuse etc. shortcoming.

In the treatment process of existing electroplating wastewater processing, there is complex process in chemical method, physico-chemical process etc., energy consumption is large, cost is high, running expense is high, produce the shortcomings such as secondary pollution; And though biological process has the advantages such as comprehensive treatment capability is strong, process control is simple, sludge quantity is few, from use angle, also have that function yeast reaction efficiency is low, reproduction speed is slow, process shipwreck in reuse, can not guarantee the shortcomings such as wastewater treatment stably moves.
