Disposable butyronitrile glove production wastewater treatment method and reuse water treatment process

Abstract

The invention discloses a disposable butyronitrile glove production wastewater treatment method. The method comprises the following steps: collecting incoming water through an adjusting tank; removing slag through a coagulation air flotation machine 1; cooling through a cooling tower; enabling the wastewater to pass through a hydrolysis acidification tank and a biological selection tank, and sequentially pass through a first-stage A reaction tank, a first-stage O reaction tank, a second-stage A reaction tank and a second-stage O reaction tank for treatment; separating the sludge from water through an MBR membrane tank; and sterilizing the sewage, carrying out deslagging and discharged, and pressing the sludge into sludge cakes to be transported outwards. The invention relates to a disposable butyronitrile glove production reuse water treatment process, which comprises: filtering incoming water through a multi-medium filter; pumping to a reverse osmosis device, and treating the generated concentrated water through a catalytic ozonation tower and a two-stage A / O tank; and feeding the sewage enters a Fenton reaction tank to be treated. According to the present invention, after the two-stage RO filtration concentration, 70% of the purified water is reused for production, and 30% of the concentrated water is further deeply treated to achieve the emission requirement and then is discharged.

Description

technical field [0001] The invention relates to the technical field of waste water treatment for the production of disposable nitrile gloves, in particular to a treatment method for waste water produced in the production of disposable nitrile gloves and a recycling water treatment process. Background technique [0002] Disposable nitrile gloves are a kind of chemical synthetic material, which is made of acrylonitrile and butadiene through special process and formula improvement. The air permeability and comfort are close to latex gloves, and at the same time, it will not cause any skin allergies. Nitrile gloves have been developed in recent years. During production, they can reach level 100 and level 1000 after cleaning. Disposable nitrile gloves are mostly powder-free. [0003] Nitrile rubber is an irregular copolymer, which is mainly obtained by emulsion polymerization or solution polymerization of two monomers, acrylonitrile and butadiene. The rubber has very good oil re...

Problems solved by technology

[0004] The purpose of the present invention is to provide a treatment method for disposable nitrile glove production waste water and a process for reclaimed water, which has 70% of the purified water to be reused for production after two-stage RO filtration and concentration, and 30% of the concentrated water for further advanced treatment The advantage of discharge after meeting the discharge requirements solves the problem that there are many toxic and harmful substances in the wastewater generated in the production process of nitrile rubber, such as acrylonitrile, acrylamide, acrylic acid, acrolein, etc. These substances have strong toxicity, It has an inhibitory effect on microorganisms, and the concentration of COD and nitrogen-containing pollutants in nitrile rubber wastewater is very high, which is a problem of refractory organic wastewater
