Printing-dyeing wastewater purifier and utilization method of printing-dyeing wastewater purifier

Abstract

The invention belongs to the field of wastewater treatment, and relates to a printing-dyeing wastewater purifier and a utilization method of the printing-dyeing wastewater purifier. The printing-dyeing wastewater purifier is characterized by being prepared from the following raw materials in terms of parts by weight: 15-25 parts of polyacrylamide, 10-15 parts of bamboo charcoal, 15-30 parts of sodium carbonate, 15-25 parts of concentrated hydrochloric acid, 15-25 parts of sodium sulfate, 15-25 parts of perlite, 5-15 parts of sawdust, 25-35 parts of diatomaceous earth, 15-20 parts of bentonite, 10-15 parts of potassium permanganate, 20-30 parts of quaternary ammonium salt, 5-10 parts of fruit shell filter materials, 10-18 parts of medicinal stone, 15-25 parts of coconut shell activated carbon and 20-35 parts of cation exchange resin. The printing-dyeing wastewater purifier and the utilization method of the purifier have the advantages that not only can printing-dyeing wastewater with high erchrominance and higher concentration be treated, but also the printing-dyeing wastewater after the treatment of the purifier is colorless and odorless, and has obviously-reduced CODcr (Chemical Oxygen Demand chromium) value and BOD5 (Biochemical Oxygen Demand 5) value; moreover, secondary pollution can be avoided in the process of treating the printing-dyeing wastewater by utilization of the purifier, and the effects of low cost, simple operation and convenience in promotion are achieved.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a water purifying agent for dyed wastewater and a method for using the water purifying agent. Background technique [0002] Since the reform and opening up, my country's textile industry has been developing more and more. Among them, the printing and dyeing industry has also developed extremely rapidly, and its production capacity has expanded. A large amount of water is consumed in production, and a large amount of waste water is produced at the same time. This printing and dyeing waste water has high chroma and complex components, and cannot be discharged directly. It is very difficult to treat. Therefore, people spend a lot of material and financial resources to solve this problem. In the prior art, there are many kinds of water purifiers used to treat printing and dyeing wastewater, such as basic aluminum chloride, aluminum sulfate, ferrous sulfate and other ino...

[0002] Since the reform and opening up, my country's textile industry has been developing more and more. Among them, the printing and dyeing industry has also developed extremely rapidly, and its production capacity has expanded. A large amount of water is consumed in production, and a large amount of waste water is produced at the same time. This printing and dyeing waste water has high chroma and complex components, and cannot be discharged directly. It is very difficult to deal with it. Therefore, people spend a lot of material and financial resources to solve this problem.

In the prior art, there are many kinds of water purifiers used to treat printing and dyeing wastewater, such as basic aluminum chloride, aluminum sulfate, ferrous sulfate and other inorganic coagulants, which have poor decolorization effect on printing and dyeing wastewater, unstable treatment effect, and cannot effectively decolorize Color removal of printing and dyeing wastewater
