As an important city in the petroleum, chemical, metallurgical and shipbuilding industries in Liaoning Province, Huludao City produces up to 120,000 tons of hazardous waste each year. The most important feature of the newly built Liaoxi Environmental Protection Industrial Park is “using waste to treat wasteâ€, turning waste and even hazardous waste into resources.
According to the person in charge of the Industrial Park Development Co., Ltd., the center used high-temperature distillation at 350°C to recover substances such as stilbene and marine fuel that have re-use value when disposing of waste oil, waste organic solvents, and other chemical substances. , And generate new oil products, and distillation residues, etc. can be used as incinerator fuel. In the treatment of iron mud, sewage sludge, and sludge, the park uses waste oil as a fuel and heats the sludge at 1000°C in an incinerator to eliminate toxic and hazardous substances. The waste heat generated after high-temperature incineration is collected by pipelines to be used for heating in the park.
The project has a high level of automation, which can achieve a total annual incineration disposal of 27,000 tons of mixed sludge and iron mud, and annual disposal of 25,000 tons of waste oil solvent.
