Example Embodiment

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0036] See figure 1 , An embodiment provided by the present invention:

[0037] The initial water quality of the nitrile glove production process wastewater produced by a company in Hebei is 400mg / L, BOD5 130mg / L, total nitrogen 300mg / L, salt content 1200 mg / L, SS 500mg / L, pH 7-8.5, It is treated by a method for treating wastewater from a nitrile glove production process of the present invention, and the designed treatment capacity is 4500m3 / d, and the main process steps are:

[0038] (1) The waste water passes through a 5mm mechanical grid, and then passes through a collection well and a primary sedimentation tank, and then is upgraded to two...

Abstract

The invention relates to a treatment method of nitrile glove production technological waste water, and belongs to the technical field of organic waste water treatment. The method comprises is characterized in that the waste water sequentially passes through a grating, a water collecting well, an initial sedimentation tank, a first-stage air flotation machine, a regulating tank, an ozone oxidationtank, a hydrolytic acidification tank, a first-stage A tank, an O tank, a second-stage A tank, a second-stage air floatation machine and a clear water tank, and the waste water is finally discharged after standards are reached. The method has the advantages that the operation cost is low, the operation is simple, suspended solid, COD, total nitrogen and the like in a nitrile glove production technology can be efficiently removed, and finally the waste water reaches the first-level A discharging standard of <Discharge Standard of Pollutants in Urban Sewage Treatment Plant> (GB 18918-2002).

Description

technical field [0001] The invention relates to a method for treating waste water in the production process of nitrile gloves, which belongs to the technical field of refractory organic waste water treatment. Background technique [0002] Nitrile glove production process wastewater mainly comes from "hand mold cleaning, primary leaching, secondary leaching, cooling mold, water inspection, equipment and ground washing" and other processes. Nitrile gloves are made of nitrile latex, which is made of butadiene and acrylonitrile by emulsion polymerization. Nitrile glove production process wastewater has certain biological toxicity. In addition, the BOD5:COD ratio of nitrile glove production process wastewater is less than 0.3, and its biodegradability is poor. At the same time, this type of wastewater also has the characteristics of high suspended solids, large water volume, and high chroma. It is currently one of the most difficult organic wastewater to treat. [0003] The pat...
