With the continuous improvement of living standards, people's demand for health products is also increasing. The amount of sewage generated during the health care product production is also increasing, and the application is gradually expanding. Below, Fujia Environment will take you to learn about the industrial sewage treatment technology used in the health care product industry.
In the wastewater treatment process of health products production, a combined process of "hydrolysis and acidification + biological contact oxidation + aerated biological filter " is used to process it.
The sewage for health care products production is discharged into the adjustment pool by the pipeline to adjust the water quality and water volume. An online pH meter is installed in the adjustment tank, and lye is automatically added according to the inlet pH value. The effluent of the regulator tank is lifted from the pump to the hydrolysis and acidification tank for anaerobic reaction, which can improve the biochemical properties of the wastewater while removing part of COD. The water from the hydrolyzed acidification tank flows into the biological contact oxidation tank to remove most of the COD and some ammonia nitrogen. The effluent of the biological contact oxidation tank flows into the precipitation tank, and then enters the aerated biological filter to further remove COD and ammonia nitrogen to ensure that the effluent is stable and discharged to meet the standards. The sludge in the sedimentation tank and the aerated biological filter backwashing water in the sludge concentration tank are entered. After the sludge is concentrated, the plate-frame filter is filtration, the filtrate is refluxed to the adjustment tank, and the mud cake is transported out of the landfill.
Using this health care product to produce sewage treatment process in sewage SS mainly relies on sedimentation tanks and aeration biological filters to remove. In the hydrolysis and acidification stage of , part of COD and part of ammonia nitrogen can be effectively removed, and the biochemical properties of wastewater are improved. The subsequent process is operated under low organic load conditions, and the COD removal rate of the entire system can reach 91%. NH3-N is effectively removed in biological contact oxidation tanks and aeration biological filters.
After the entire health product production sewage treatment process, the water effluent can meet the emission standards. If you have any questions about the wastewater treatment for health care products production, please consult Fujia environmental engineer .
