Abstract
The invention discloses a coagulant for treating spinning, printing and dyeing wastewater. The coagulant comprises ferric trichloride, ferric sulfate, a maleic acid-crylic acid polymer and bentonite. The coagulant is used for treating spinning, printing and dyeing wastewater, after being filtered by using grids, the spinning, printing and dyeing wastewater enters a settling pond, the coagulant is fed into the spinning, printing and dyeing wastewater in the settling pond for treatment, the generated aggregate is solid, not easy to damage, good in settling property and good in decoloring and oil-removing effects, and moreover the coagulant disclosed by the invention is large in pH value application range, high in thermal stability and stable in effect.
Description
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of processing textile printing and dyeing wastewater coagulating agent.
Background technology
Textile printing and dyeing industry is industrial wastewater discharge rich and influential family, and textile printing and dyeing wastewater has the features such as the water yield is large, organic pollutant content is high, colourity dark, alkalescence is large, change of water quality is large, belongs to unmanageable trade effluent.Cotton textiles industry waste water, mainly from dyeing and finishing workshop section, comprises destarch, boiling-off, bleaching, mercerising, dyeing, stamp and arrangement etc.How effectively to process.
In recent years due to the development of man made fiber fabric, the progress of the rise of Silk and finishing process in printing and dye-ing technology, make the bio-refractory organism such as PVA slurry, artificial silk alkaline hydrolysis thing (being mainly O-phthalic acids material), New-type adjuvant enter in a large number textile printing and dyeing wastewater, its COD concentration also rises to 2000～3000mg/L by original hundreds of mg/L, thereby make original biological treatment system COD clearance drop to 50% left and right from 70%, even lower.Traditional biological treatment has been subject to serious challenge; Traditional chemical precipitation and By Bubble-floating Method are only also 30% left and right to the COD clearance of this class textile printing and dyeing wastewater.
Summary of the invention
Object of the present invention is exactly to provide a kind of processing textile printing and dyeing wastewater coagulating agent for the defect of above-mentioned existence.This coagulating agent is for the treatment of textile printing and dyeing wastewater, textile printing and dyeing wastewater first after grid filtration, is entered to settling tank, coagulating agent is dropped in the textile printing and dyeing wastewater in settling tank and processed, I am solid in the cohesion generating, survivable, sedimentation function is good, and decolouring, deoiling effect is good, and, it is large that coagulating agent of the present invention adapts to pH value scope, and thermostability is high, effect stability.
A kind of processing textile printing and dyeing wastewater of the present invention is to comprise iron trichloride, ferric sulfate, maleic acid-acrylic acid copolymer, wilkinite by coagulating agent technical scheme.
Specifically comprise following composition by weight: comprise iron trichloride 8-20 part, ferric sulfate 15-25 part, maleic acid-acrylic acid copolymer 3-5 part, wilkinite 5-15 part.
Preferably, comprise following composition by weight: comprise 12 parts of iron trichlorides, 23 parts, ferric sulfate, 5 parts of maleic acid-acrylic acid copolymers, 10 parts of wilkinites
This coagulating agent also contains white lime.
White lime accounts for the 2-8% of the weight percent of coagulating agent.
Preferably, white lime account for coagulating agent weight percent 5%.
Described a kind of processing textile printing and dyeing wastewater coagulating agent, every 1L sewage drops into the coagulating agent of 200-500mg.
Beneficial effect of the present invention is: this coagulating agent is for the treatment of textile printing and dyeing wastewater, textile printing and dyeing wastewater first after grid filtration, is entered to settling tank, coagulating agent is dropped in the textile printing and dyeing wastewater in settling tank and processed, I am solid in the cohesion generating, survivable, sedimentation function is good, and decolouring, deoiling effect is good, and, it is large that coagulating agent of the present invention adapts to pH value scope, and thermostability is high, effect stability.
