Abstract
The invention discloses a kind of coagulant processing textile waste, including aluminum sulfate, sodium aluminate, activated silicic acid, 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 tank, coagulant is put in the textile printing and dyeing wastewater in sedimentation tank 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 stability is high, effect stability.
Description
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of coagulant processing textile waste.
Background technology
Textile printing and dyeing industry is industrial wastewater discharge rich and influential family, mainly contains in the dirt on textile fabric, oils and fats, salt and the course of processing additional various slurries, dyestuff, surfactant, auxiliary agent, soda acid etc. in sewage.Textile printing and dyeing wastewater has the features such as the water yield is big, organic pollution content is high, colourity is deep, change of water quality is big, belongs to intractable industrial wastewater.
Development along with the fine fabric of chemistry, the raising that the rise of Silk and finishing process in printing and dye-ing require, the hardly degraded organic substances such as PVA slurry, artificial silk alkaline hydrolysis thing, new dye, auxiliary agent are made to enter textile printing and dyeing wastewater in a large number, traditional waste water treatment process is constituted serious challenge, and COD concentration also rises to 3000～5000mg/l from original hundreds of milligrams per liter.
Summary of the invention
The purpose of the present invention is aiming at the defect of above-mentioned existence and provides a kind of coagulant processing textile waste.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 tank, coagulant is put in the textile printing and dyeing wastewater in sedimentation tank and process, being applicable to the textile waste that change of water quality is big, flocculating result is good, and speed is fast, acidproof, heat resistance good, is adapted to the waste water that water temperature changes greatly.
The coagulant technical scheme that the present invention a kind of processes textile waste is, including aluminum sulfate Al2(SO4)3·18H2O, sodium aluminate Na2Al2O4, activated silicic acid, polyacrylamide, bentonite.
Activated silicic acid is sodium silicate Na2O·nSiO2, wherein, n=2.4-2.6.
Specifically include following component by weight: aluminum sulfate 10-25 part, sodium aluminate 5-18 part, activated silicic acid 3-8 part, polyacrylamide 2-4 part, bentonite 5-15 part.
Preferably, including following component by weight: 20 parts of aluminum sulfate, sodium aluminate 15 parts, activated silicic acid 7 parts, polyacrylamide 3 parts, bentonite 10 parts.
This coagulant is possibly together with sodium acetate.
Sodium acetate accounts for the 2-8% of the percentage by weight of coagulant.
Preferably, sodium acetate account for coagulant percentage by weight 5%.
Described a kind of coagulant processing textile waste, every 1L sewage puts into the coagulant of 300-600mg.
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 tank, coagulant is put in the textile printing and dyeing wastewater in sedimentation tank and process, being applicable to the textile waste that change of water quality is big, flocculating result is good, and speed is fast, acidproof, heat resistance good, is adapted to the waste water that water temperature changes greatly.
