Abstract
The invention discloses a kind of process textile printing and dyeing wastewater coagulant, including ferric trichloride, ferric sulfate, maleic acrylic copolymer, bentonite.This coagulant is used for processing textile printing and dyeing wastewater, after textile printing and dyeing wastewater is first passed through grid filtration, enter sedimentation basin, coagulant is put in the textile printing and dyeing wastewater in sedimentation basin and process, I am solid in the cohesion generated, survivable, sedimentation function is good, decolouring, deoiling effect good, and, it is big that the coagulant of the present invention adapts to pH value range, and heat endurance is high, effect stability.
Description
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of process textile printing and dyeing wastewater coagulant.
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 big, organic pollution content is high, colourity is deep, alkalescence is big, change of water quality is big, belongs to intractable industrial wastewater.Cotton textiles industry waste water is essentially from dyeing and finishing workshop section, including desizing, boiling-off, bleaching, mercerising, dyeing, stamp and arrangement etc..The most effectively process.
In recent years due to the development of science fabric, the rise of Silk and the progress of finishing process in printing and dye-ing technology, the bio-refractory organic matters such as PVA slurry, artificial silk alkaline hydrolysis thing (mainly O-phthalic acids material), New-type adjuvant are made to enter textile printing and dyeing wastewater in a large number, its COD concentration is also risen to 2000～3000mg/L by original hundreds of mg/L, so that original biological treatment system COD clearance drops to about 50% from 70%, even lower.Traditional biological treatment is by serious challenge；The gentle float glass process of traditional chemical precipitation is also only about 30% to the COD clearance of this kind of textile printing and dyeing wastewater.
Summary of the invention
The purpose of the present invention is aiming at the defect of above-mentioned existence and provides a kind of and process textile printing and dyeing wastewater coagulant.This coagulant is used for processing textile printing and dyeing wastewater, after textile printing and dyeing wastewater is first passed through grid filtration, enter sedimentation basin, coagulant is put in the textile printing and dyeing wastewater in sedimentation basin and process, I am solid in the cohesion generated, survivable, sedimentation function is good, decolouring, deoiling effect good, and, it is big that the coagulant of the present invention adapts to pH value range, and heat endurance is high, effect stability.
A kind of textile printing and dyeing wastewater coagulant technical scheme that processes of the present invention is, including ferric trichloride, ferric sulfate, maleic acid-acrylic acid copolymer, bentonite.
Specifically include following component by weight: include ferric trichloride 8-20 part, ferric sulfate 15-25 part, maleic acid-acrylic acid copolymer 3-5 part, bentonite 5-15 part.
Preferably, including following component by weight: include ferric trichloride 12 parts, 23 parts of ferric sulfate, maleic acid-acrylic acid copolymer 5 parts, bentonite 10 parts
This coagulant is possibly together with white lime.
White lime accounts for the 2-8% of the percentage by weight of coagulant.
Preferably, white lime account for coagulant percentage by weight 5%.
Described a kind of textile printing and dyeing wastewater coagulant that processes, the coagulant of every 1L sewage input 200-500mg.
The invention have the benefit that this coagulant is for processing textile printing and dyeing wastewater, after textile printing and dyeing wastewater is first passed through grid filtration, enter sedimentation basin, coagulant is put in the textile printing and dyeing wastewater in sedimentation basin and process, I am solid in the cohesion generated, survivable, sedimentation function is good, decolouring, deoiling effect good, and, it is big that the coagulant of the present invention adapts to pH value range, and heat endurance is high, effect stability.
Detailed description of the invention:

Embodiment 3
The a kind of of the present invention processes textile printing and dyeing wastewater coagulant, the following component including by weight: include ferric trichloride 8 parts, 15 parts of ferric sulfate, maleic acid-acrylic acid copolymer 3 parts, bentonite 5 parts.
This coagulant is possibly together with white lime.
White lime accounts for the 8% of the percentage by weight of coagulant.
Described a kind of textile printing and dyeing wastewater coagulant that processes, the coagulant of every 1L sewage input 500mg.
Embodiment 4
The a kind of of the present invention processes textile printing and dyeing wastewater coagulant, the following component including by weight: include ferric trichloride 20 parts, 25 parts of ferric sulfate, maleic acid-acrylic acid copolymer 4 parts, bentonite 10 parts.
Described a kind of textile printing and dyeing wastewater coagulant that processes, the coagulant of every 1L sewage input 200mg.
Coagulant in above example is used for processing textile printing and dyeing wastewater, after textile printing and dyeing wastewater is first passed through grid filtration, enters sedimentation basin, is put into by coagulant in the textile printing and dyeing wastewater in sedimentation basin and process.After process time 4.5h, effect is as shown in table 1:
