Abstract
The invention discloses a composite flocculant for treating printing and dyeing wastewater and a preparation method of the composite flocculant. The composite flocculant for treating the printing and dyeing wastewater comprises the following raw materials in parts by mass: 30-40 parts of acrylamide, 10-15 parts of tetraethylenepentamine, 35-40 parts of sodium silicate, 10 to 20 parts of ammonium chloride, 5-8 parts of sodium hydroxide and 30-35 parts of water. According to the composite flocculant disclosed by the invention, all components are reasonably compounded, so that the flocculant has a better decolorization effect and a relatively high removal rate for all dyestuffs. Furthermore, the preparation method of the flocculant is simple and easy to carry out and the production cost can be effectively reduced.
Description
Technical field
The invention belongs to field of waste water treatment, be specifically related to composite flocculation agent and preparation method thereof for a kind for the treatment of of dyeing wastewater.
Background technology
Along with developing rapidly of China's textile industry, the water pollution of bringing because of dyeing waste water also more and more receives people's concern.Dyeing waste water refers to the waste water discharging carrying out fabric post-process treatment, the complicated component of dyeing waste water, and organic pollutant content is high, and COD and BOD are higher, more difficult.Existing wastewater treatment is mainly used single inorganic salt as flocculation agent, still has large usage quantity, the shortcoming that cost is high, flocculating effect is not good.
Therefore developing a kind of composite flocculation agent is efficiently existing field technical barrier urgently to be resolved hurrily.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and composite flocculation agent and preparation method thereof for a kind for the treatment of of dyeing wastewater is provided, the effective organism in sedimentation waste water of composite flocculation agent for treatment of dyeing wastewater of the present invention.
Technical scheme of the present invention:
Treatment of dyeing wastewater composite flocculation agent, comprises the following raw material according to mass fraction meter: acrylamide 30-40 part, tetren 10-15 part, water glass 35-40 part, ammonium chloride 10-20 part, sodium hydroxide 5-8 part, water 30-35 part.
Described treatment of dyeing wastewater composite flocculation agent, comprises the following raw material according to mass fraction meter: 30 parts of acrylamides, 10 parts of tetrens, 35 parts of water glass, 10 parts of ammonium chlorides, 5 parts, sodium hydroxide, 30 parts, water.
Treatment of dyeing wastewater is as follows by the preparation method of composite flocculation agent: according to quality proportioning, by acrylamide, tetren, water glass, ammonium chloride, add in reactor successively, sodium hydroxide is added to the water to preparation aqueous sodium hydroxide solution, add reaction wherein aqueous sodium hydroxide while stirring, constant temperature stirs after 2h, treats that solution naturally cooling obtains treatment of dyeing wastewater composite flocculation agent.
Beneficial effect: treatment of dyeing wastewater of the present invention is rationally composite by each component with composite flocculation agent, make this flocculation agent all have good decolorizing effect and higher clearance to all kinds of dyestuffs, and preparation method of the present invention is simple, can effectively save production cost.
