Wastewater treatment in hazardous waste disposal center
Application background:
Hazardous wastes are wastes that pose a significant threat to human health or the environment when not handled, stored, transported, treated and disposed. With the development of industry, hazardous waste discharged from industrial production processes is increasing, and a number of high-standard hazardous waste disposal centers have been established in various regions.
Hazardous waste is corrosive, toxic, flammable, reactive or infectious and other dangerous characteristics, random dumping or improper disposal and utilization will seriously endanger human health, and even cause damage to the ecological environment that is difficult to restore. Strengthening the prevention and control of hazardous waste pollution is an important guarantee for improving the quality of water, air and soil environment, controlling environmental risks, and maintaining human health. It is also the last barrier for environmental protection.
The wastewater treated by the sewage treatment system of the hazardous waste disposal center is mainly production wastewater and domestic sewage, of which production wastewater includes incineration workshop drainage, physical and chemical workshop drainage, leachate, flushing wastewater, laboratory wastewater, etc., which has the characteristics of large water quality fluctuation and high treatment difficulty, and generally requires the effluent of the sewage treatment system to meet the requirements of plant reuse.
The existing engineering practice shows that: Qing Da Guohua flat membraneMBRThe system has the following advantages in the wastewater treatment of hazardous waste disposal center:
（1） Qing Da Guohua Adopting“materialization+hydrolytic acidification+flat membraneMBR”The combined process has the advantages of good treatment effect, strong impact load and high sludge volume. Since the microorganisms are completely intercepted in the bioreactor, it is beneficial to the retention and growth of microorganisms with slow proliferation, and to the improvement of the degradation efficiency of refractory organic matter.
（2） The effluent quality is high quality and stable, and the suspended solids and turbidity are close to zero, which can be directly used as ground cleaning water and circulating cooling water for reuse in the hazardous waste disposal center.
（3） High degree of automation, no permanent operation and maintenance personnel, can achieve online monitoring and remote control.
