Jilin Petrochemical Wastewater Treatment Technology Passed Acceptance

Recently, the research project of simulation and optimization of biochemical system of sewage treatment plant developed by Jilin Petrochemical Research Institute passed the acceptance of experts
.

Experts believe that the results of this research can directly guide sewage treatment plants to carry out industrialization tests for optimized operation of biochemical units, reduce the energy consumption of sludge return, reduce the amount of biochemical sludge, and realize energy saving and emission reduction
.

After the implementation of optimized operation and industrialization, it can reduce the energy consumption of sludge return by 3 million yuan, reduce the amount of biochemical sludge discharge by 3,000 tons, and reduce the cost of sludge outsourcing disposal by 2.

Jilin Petrochemical's sewage treatment plant has been in operation for many years.
Compared with similar domestic sewage treatment plants, there are problems such as high operating costs of biochemical units, high residual sludge discharge, and high treatment and disposal costs
.

According to the results of biochemical effluent water quality analysis, the COD of biochemical effluent still has room to decrease

To this end, the Jilin Petrochemical Research Institute has carried out a simulation and optimization study on the biochemical unit of the sewage treatment plant
.

Researchers conduct experimental research on 4 series of influent water quality characteristic parameters of sewage treatment plant biochemical units, form a database of influent water quality characterization parameters, establish a mathematical model of sewage treatment plant biochemical units, and carry out water quality characterization parameter tests of sewage treatment plant intake network water quality Researched, formed a water quality characteristic parameter database of the intake network, and established a mathematical model of the sewage system of the Jilin Petrochemical District

Subsequently, the researchers carried out a simulation study on the impact of wastewater quality and quantity fluctuations on the biochemical effluent of the sewage treatment plant at the discharge outlet of each production plant, and determined the discharge limit; and conducted a simulation optimization study on the biochemical unit of the sewage treatment plant to determine an optimized operation plan for the sewage treatment Provide technical support for low-cost and stable operation of plant biochemical units
