Daqing Refining & Chemical's bio-purification absorption tower has been installed before the end of the day, marking the company's investment in more than 15 million yuan in the construction of the "unorganized waste gas collection and treatment device" phase I project entered the final stage, will soon be put into use. It is understood that the use of microbial oxidative degradation technology to dispose of unorganized exhaust gas that has been emitted from chemical wastewater is the first case in the country.
Daqing Lianhua is a large water user in the area. With the continuous development and expansion of the chemical industry, the amount of waste water discharged by the company during the production process has also increased, and the composition of various harmful substances in the sewage has become increasingly complex. In order to completely solve the atmospheric environmental pollution caused by the unorganized gases that have been volatilized from industrial wastewater, the company decided to use bioabsorption to process it after repeated argumentation and invested in the construction of the first-phase project in September last year.
The technology is mainly to discharge the unorganized and volatile gases in the sewage treatment station into the biological purification absorption tower through closed collection, and then use the microbial oxidative degradation technology to decompose the pollutants in the exhaust gas into sulfur dioxide, nitrogen, carbon dioxide and water, etc. Substances are finally discharged into high-altitude atmosphere after being absorbed and processed by the carbon fiber absorption device.
