1. In terms of sewage treatment, the Ministry continuously strengthens the management and control of sewage treatment process, and timely adjusts the process parameters of sewage treatment devices according to the incoming water situation of the production and operation departments ahead, so as to keep the sewage indicators within the standard range and achieve the effect of less dosing.
2. The quality management of chemicals has also been strengthened. In addition to testing fixed batches of added chemicals, the quality of random sampling inspection is also increased to ensure the quality of added chemicals. After 10 months' exploration, the proportion of various drugs was reasonably optimized, and the effect of less dosage and quick effect was achieved.
3. Optimize the production process, reduce costs and improve efficiency. Focusing on the four major businesses of fresh water, circulating water, chemical water and sewage, we will build a system of whole system, whole process and full coverage, and establish a management and control mode of "daily tracking, weekly summary, monthly notification and strict assessment" to make the project effective.
