Abstract
The invention discloses a textile dyeing wastewater treatment method, relating to the technical field of wastewater treatment. The method comprises the following steps: introducing textile dyeing wastewater into a filter, filtering, collecting the filtrate, and transferring the filtrate into a dust remover to perform smoke prevention and dust removal treatment; transferring into a reaction tank, adding a flocculant, stirring, standing and filtering; adding sodium hypochlorite to perform decolorization treatment until the textile dyeing wastewater becomes colorless; and carrying out reverse osmosis treatment through a reverse osmosis membrane, and directly discharging the qualified textile dyeing wastewater. The method has the advantages of simple technique, low cost and favorable treatment effect.
Description
Technical field
The present invention relates to technical field of waste water processing, especially a kind of textile printing and dyeing wastewater treatment process.
Background technology
Textile printing and dyeing industry is industrial wastewater discharge rich and influential family, according to statistics, and the textile printing and dyeing wastewater amount approximately 5 × 10 of whole nation discharge every day
6cubic meter, and in waste water, organic concentration is high, complicated component, and colourity is dark, and pH value changes greatly, and water quality and the water yield change greatly, belong to and more unmanageable trade effluent.The processing of textile printing and dyeing wastewater adopts biochemical method and absorption method conventionally, and biochemical method treatment effect is undesirable, and in absorption method, single adsorption agent is difficult to effective treatment of dyeing and printing, and body refuse amount is large, and aftertreatment is more difficult, easily causes secondary pollution.
Summary of the invention
The object of this invention is to provide the textile printing and dyeing wastewater treatment process that a kind of cost is low, technique is simple, respond well.
In order to address the above problem, the technical solution used in the present invention is: this textile printing and dyeing wastewater treatment process, comprises the following steps:
A, textile printing and dyeing wastewater is passed into strainer, filter, collect filtrate, described filtrate is proceeded to and in fly-ash separator, carries out smoke prevention and dust control processing;
B, proceed to reaction tank, add flocculation agent, stir, leave standstill, filter; Wherein, described flocculation agent is polyacrylamide, Tai-Ace S 150, one or more in ferric sulfate;
C, add the clorox processing of decolouring, become colorless to textile printing and dyeing wastewater;
D, carry out reverse-osmosis treated by reverse osmosis membrane, qualified textile printing and dyeing wastewater is directly discharged.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, the present invention combines physics and chemistry method, adopts multiple tracks handling procedure, and treated waste water not only reaches emission standard, also can be back to workshop recycling.
2, operation of the present invention is simple, cost is low, treatment effect is better.
