Abstract
The present invention relates to a multicomponent compound agent for waste water treatment in textile printing and finishing and a treatment process thereof. The multicomponent compound agent for waste water treatment in textile printing and finishing is formed by mixing six kinds of agents of polymeric ferric sulfate, ferric chloride, poly dimethyl diallyl ammonium chloride, polyacrylamide, phospham and sodium carboxymethyl cellulose, wherein the partition rates of the six kinds of agents according to weight are 80% to 90% of polymeric ferric sulfate, 2% to 5% of ferric chloride, 2% to 5% of poly dimethyl diallyl ammonium chloride, 2% to 5% of polyacrylamide, 1% to 3% of phospham and 1% to 3% of sodium carboxymethyl cellulose. The treatment process is that the multicomponent compound agent is injected in waste water and is uniformly mixed through high-speed agitation; the multicomponent compound agent overflows into a sinking pool and flows into two sinking pools through aeration; the multicomponent compound agent is decolorized through sand filtration activated carbon to obtain clear and transparent water. The present invention is adopted; after the waste water is treated, the waste water can be recovered and used periodically; the waste water does not need discharging. The water treatment has low cost. The pollution to a water body can be reduced and water quality achieves the standard of the class of GB/T14848-93V.
Description
Technical field
The invention belongs to the printing technology field, be specifically related to whole waste water conditioner of weaving seal and treatment process thereof.
Background technology
The main source of waste water is in dyeing and finishing workshop section in textile industry and rag trade, and because the difference of various clothes, selected dyestuff kind difference, thereby the waste water shade differs, the composition complexity, single water conditioner is difficult to adapt to the needs of wastewater treatment comprehensively.Cause existing wastewater treatment complex procedures, cost is too high, and enterprise can't bear the heavy load for this reason.Therefore, for adapting to the needs that various dyeing and printing sewages are handled, as the simplest treatment process how, dyeing and printing sewage is handled obtain regeneration to be produced with minimum processing cost and utilized, accomplish not have discharging enterprise, the protection environment has great economic implications and realistic meaning.
Summary of the invention
Purpose of the present invention is intended to overcome above-mentioned the deficiencies in the prior art, proposes that a kind of cost is low, the whole waste water conditioner of the weaving of good waste water treatment effect seal and treatment process thereof.
Realize the technical scheme of above-mentioned purpose:
The whole waste water conditioner of a kind of weaving seal is by medicament bodied ferric sulfate ([Fe

nSix kinds of medicaments mix.
Described medicament per-cent by weight ratio is: bodied ferric sulfate 80-90%, iron(ic) chloride 2-5%, Poly Dimethyl Diallyl Ammonium Chloride 2-5%, polyacrylamide 2-5%, phosphorus ammonium 1-3% and Xylo-Mucine 1-3%.
The whole waste water treatment process of a kind of weaving seal comprises former water → coagulation → aeration → clearly heavy → sand filtration → processing steps such as absorption, wherein:
Coagulation is to point to the per-cent that mixes by weight ratio in the former water to be: the medicament of bodied ferric sulfate 80-90%, iron(ic) chloride 2-5%, Poly Dimethyl Diallyl Ammonium Chloride 2-5%, polyacrylamide 2-5%, phosphorus ammonium 1-3% and Xylo-Mucine 1-3%.
Adopt technique scheme, beneficial technical effects of the present invention is: by adding bodied ferric sulfate, the colloidal solid that suspends in the water is electrically neutralized, impel the mutual coagulation of ion phase and produce the adsorption bridging crosslinked action, impel suspended ion to condense. by adding iron(ic) chloride, can increase a kind of negatively charged ion more, remedy the small part flocs unit that bodied ferric sulfate can not form. help the bodied ferric sulfate decolouring by adding Poly Dimethyl Diallyl Ammonium Chloride, eliminate the unusual smell. by adding polyacrylamide, impel the suspended substance rapid precipitation. by adding the phosphorus ammonium, adjust the pH value of the aqueous solution, improve the stability of the bodied ferric sulfate aqueous solution. by adding Xylo-Mucine, can improve the positively charged ion number that mixes water purification agent. after these six kinds of medicaments are compound, in the sewage coagulation process, utilize its affinity separately, performance main effect and booster action separately makes the rapid reaction precipitation of sewage separately.And organic and flocculation agent inorganic compounding adds simultaneously, to biochemical oxygen demand (BOD
5) and chemical oxygen demand (COD
Cr) rate of removing is also the highest.This medicament positive polarity is strong, and the micro-floccule that utilizes strong hydrolysising group hydrolysis to form takes off surely micelle, makes a large amount of pigments because joint effect also forms flco and precipitates.In addition, the combination of medicament of the present invention is answered scope wide (between 2-13) to the pH value of water quality, to various treatment of dyeing wastewater effect no significant differences, COD
Cr, BOD
5Clearance is about 80%.Through water quality analysis, close symbol GB/T14848-93V class water quality standard, recyclable utilization again.
Below by embodiment, the present invention is further illustrated:
