Type of wastewater: hazardous waste disposal plant production wastewater?
Example of project: Hebei Fenghua Environmental Protection Hazardous Waste Disposal Plant Production Wastewater Treatment Project
Hazardous Waste Disposal Wastewater Case Description: According to the customer to provide wastewater information, professional environmental protection companies need to deal with the whole plant incineration plant, physical and chemical treatment plant, comprehensive utilization of the production of wastewater generated by the workshop and the tank area, the plant's early stage of rainwater, sewage, vehicle wash water, analysis, laboratory drainage water, etc. Drainage water, after treatment to meet the discharge standards. Drainage water of the laboratory, such as sewage water, hazardous waste disposal wastewater after treatment to meet the discharge standards.
Designed water volume: 300m3/d
Hazardous waste disposal wastewater hazards:
(1) Damage to the ecological environment. Arbitrary discharge, storage of hazardous waste disposal wastewater in the rain groundwater long-term infiltration, diffusion effect, will pollute the water body and soil, reduce the regional environmental function level.
(2) affect human health. Hazardous waste disposal wastewater through ingestion, inhalation, skin absorption, eye contact and cause toxicity, or cause combustion, explosion and other hazardous events; long-term hazards, including repeated exposure to long-term poisoning, carcinogenicity, teratogenicity, mutagenicity and so on.
(3) Restrictions on sustainable development. Hazardous waste disposal wastewater is not treated or not standardized treatment and disposal of pollution brought about by the atmosphere, water, soil, etc. will also become a constraint on the bottleneck of economic activity.
Hazardous Waste Disposal Wastewater Composition:
Hazardous Waste Disposal Wastewater in general can be categorized into four major categories:
1, heavy metal wastewater (6#): containing HW34 waste acid, HW35 waste alkali, HW16\17\21\22\32 heavy metal wastewater;
2, emulsified wastewater (1#, 2#): containing HW09 cutting fluid, emulsified oil Wastewater, dye and paint waste;
3, wastewater containing cyanide (3#): containing HW33 inorganic cyanide wastewater;
4, waste acid, waste alkali (4#, 5#)
According to the information provided by the owner and the engineering experience of Esbbe Environmental Protection, the comprehensive wastewater of the Hazardous Waste Treatment Plant has a poorer biochemistry, and the process needs to be considered as a measure for the improvement of the wastewater's biochemistry. According to the environmental protection requirements, the wastewater is treated by the wastewater treatment system and then entered into Essbay's professional MBR and RO system for membrane separation, the produced water is reused in the production line, and the concentrated water is converged into the evaporation system, and the crystallization is outsourced for treatment.
