By comparing the pollution generation and discharge status of similar enterprises at home and abroad, the causes of pollution generation were analyzed, an evaluation conclusion was drawn, the audit focus (30,000 tons/year salicylic acid plant) was determined, clean production targets were set, and a no-low-cost plan was proposed and implemented.

During the review stage, the actual measurement of the key materials for review was carried out, a balance was established and the causes of waste generation were analyzed simultaneously. The no-cost/low-cost plan was continued to be implemented, and the medium/high-cost plan was proposed.

During the stage of scheme generation and screening, 9 clean production schemes were proposed, including 6 no-cost/low-cost schemes and 3 medium/high-cost schemes.

During the determination stage of the plan, the high-cost plan for this round of review process - the energy-saving renovation of the stirring system of the F7 salicylic acid carboxylation reactor was determined.
