Liaodong Bay Petrochemical Industrial Park Wastewater Treatment Plant Reconstruction Project
Liaodong Bay Petrochemical Industrial Park Wastewater Treatment Plant reconstruction project is officially running in October 2016. With its construction and operation, the industrial wastewater has been effectively treated. The effluent water quality after treatment meets the national discharge standards, which effectively eliminate the water environmental pollution of Liao River and Bohai Sea Basin caused by wastewater discharge of Liaodong Bay Petrochemical Industrial Park. This project is paid attention and supported by the Panjin City during the construction process, has important significance to ensure the water safety and environmental protection in Liao River.
The project design scale is 30,000 m³/d, with a total investment of 99.9 million RMB. Total construction area is 17325 m³, and the construction period is 8 months.
Newland adopts ozone catalytic oxidation technology for this project, takes advantage of ozone oxidation and catalyst catalysis, oxidizes the organic pollutants in the wastewater, which could improve the biodegradability of wastewater.
PetroChina Jilin Petrochemical Wastewater Treatment Project
Jilin Petrochemical Company sewage treatment plant to deal with the scale of 6500 tons / hour, the wastewater by biochemical and physical and chemical treatment, the influent COD is greater than 120mg / L, through the ozone oxidation of advanced oxidation, effluent COD less than 90mg / L. The project ozone equipment used four 40kg / h ozone equipment (3 with 1).
Ozone oxidation process is the use of ozone oxidation of oxidative decomposition of water pollutants, has the following characteristics:
(1) strong ability to oxidize organic pollutants, strong ability to remove organic matter;
(2) the final decomposition of organic matter for the CO2 and H2O, no toxic and harmful intermediates, safe and environmentally friendly;
(3) pH value in the neutral or alkaline can be, without adjusting the pH value of sewage;
(4) ozone generator to electricity and air to produce ozone, no chemical agents, on-site safety and health;
(6) the oxidation reaction time is short, the reactor volume is small.
Ozone catalytic oxidation process has good effect, wide application range, mature technology, combined with aeration biofilter, with low operating costs, good treatment and other advantages, is the application of sewage treatment at home and abroad more of the process.
