Information Announcement on Prevention and Control of Environmental Pollution by Hazardous Waste

1. Hazardous waste generation :

Table 1 List of Hazardous Waste Generation

2. Programs to reduce the hazard of hazardous waste:

Control the amount of hazardous waste generated at the source;

Improve in-plant transportation specifications to avoid falling;

The temporary storage process of hazardous waste is strictly implemented in accordance with relevant regulations.

3. Measures to reduce the amount of hazardous waste generated and how harmful:

Improved design: Improve the level of WS-23 mother liquor rectification recovery process and reduce the generation of rectification residue;

Adopt advanced technology: improve the craftsmanship of workers, regularly inspect production equipment, and reduce the amount of waste gas generated;

Improve management: increase the utilization rate of reagents in the laboratory test process and avoid waste, thereby reducing the generation of empty reagent bottles;

Comprehensive utilization of waste: fully react in the production process to improve the recovery efficiency of the recovered solvent;

Improve the level of pollution prevention and control: buy high-quality activated carbon to improve the adsorption effect of activated carbon;

Others: Optimize the production ratio of raw and auxiliary materials.

4. Shipping measures:

The waste activated carbon is packed in a woven bag, and the bag mouth is fastened to prevent flying. The rectification residue and selenium-containing residue are prevented from leaking, and collection tools and collection buckets are provided for timely collection. Tighten the cap of the waste reagent bottle to prevent overturning.
