According to the main design parameters of the process, through reasonable determine the processing unit of the structure design calculations, while drawing the design process, but also the need for wastewater treatment plants and elevation plane for a reasonable layout and calculation. Waste water thereby removing the grille which macromolecules pollutants into the conditioning tank waste water of pH adjustment, and then by anaerobic hydrolysis acidification process easier part of degradable organic contaminant removal, while more difficult to degrade decomposition of organic macromolecules relatively simple small organic molecules, the following entry aerated biological fluidized bed, making wastewater organics and ammonia in sewage in contact with the filler can remove most, go through precipitation of secondary sedimentation tank makes wastewater suspended and dissolved organic matter can be removed, and finally in the chlorine dioxide disinfection of Escherichia coli in wastewater removal, thus achieving the wastewater discharge standards.
Treated wastewater indicators have reached the "Integrated Wastewater Discharge labeled" The (GB8978-1996) Ⅰ grade standards, COD, BOD, SS, NH3-N, the number of total coliform removal rate can reach 67%, respectively, 87%, 42%, 70%. 99%, that, a pH of 6.0 ~ 9.0, COD ≤ 100 mg / L, BOD5 ≤ 20 mg / L, SS ≤ 70 mg / L, NH¬3-N ≤ 15 mg / L, coliform count ≤ 100 num / L .
After a project budget calculations can get the plant's construction costs, the cost of the overall cost of up to XXXX million. T processing cost of $ 3.
This process has a strong impact resistance, small footprint, high efficiency, stable operation. Our emissions cuts through a lot of pollution concentration, making the quality of the water quality improvement play a positive and effective role.
