A glass fiber production wastewater treatment equipment and treatment method

Abstract

The invention discloses a treatment device and treatment method for glass fiber production wastewater. The wastewater is treated in stages, a wastewater flow dividing device is arranged, through monitoring of the attenuation degree of an infrared laser, the amount of impurities in the wastewater is judged, the more the impurities in the wastewater, the more the attenuation of the infrared laser, and the weaker the signal detected by an infrared sensor; and when the amount of the impurities in the wastewater is smaller, the wastewater directly enters a second water treatment device for softening treatment, and when the amount of the impurities in the wastewater is larger, the wastewater enters an SBR firstly for a reaction, then the reacted wastewater enters the second water treatment device for softening treatment. The treatment device and treatment method for the glass fiber production wastewater provided by the invention can perform targeted treatment according to the amount of the impurities in the wastewater, have good wastewater treatment effects, can effectively improve the treatment efficiency of the wastewater, and reduce the treatment costs.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a glass fiber production wastewater treatment equipment and treatment method. Background technique [0002] Glass fibers are made of inorganic non-metallic materials with excellent performance. During the production process, there is a step of coating the surface of the raw wire with a sizing agent. Therefore, the pollutants in the waste water of the glass fiber factory are mainly used to improve the impact of the liquid on the glass fiber. Wetting "sizing" components and suspensions such as fine glass fibers. For this type of wastewater, effective methods are first used to remove suspended matter. However, due to the light specific gravity, fine particles and slow sedimentation of organic polymer particles, the sedimentation method not only has a small loading capacity of the sedimentation tank area, but also requires a large amount of dosing. However, the general ...

For this type of wastewater, effective methods are first used to remove suspended matter, but due to the light specific gravity, fine particles and slow sedimentation of organic polymer particles, the sedimentation method not only has a small loading capacity of the sedimentation tank area, but also requires a large amount of dosing

However, the general coagulation sedimentation or coagulation air flotation is not ideal for its treatment effect.
