Over the years, the company has conscientiously implemented the environmental protection laws and regulations of the state and governments at all levels. While developing production, the company has taken environmental protection as an important way to develop the enterprise and improve economic efficiency. It has insisted on developing a circular economy and taking the road of comprehensive utilization of resources.

Dongjia recycles low-temperature heat energy in the production of sulfuric acid. 140000 tons of steam can be recycled every year, equivalent to 20000 tons of standard coal. The value of steam reaches 17 million yuan

The original waste heat and residual pressure power generation project has an annual power generation value of 13.68 million yuan, equivalent to 2950 tons of standard coal,. The new 400000 ton sulfuric acid project and the supporting waste heat power generation project generate 110 million KWh of electricity annually. After the two sets of generator units are connected to the network, they can basically meet the group's production power consumption. In the production process, one ton of coal is no longer used, and the economic benefits are significant.

The reclaimed water reuse project has realized "one water for multiple purposes and washing water for reuse", and the water reuse rate will reach more than 90%. The introduction of Sweden's advanced cooling system and Switzerland's advanced DRM water washing device, combined with six sets of closed circuit circulation systems and a water multi-purpose network, can save 400000 tons/year of water.

Four sets of titanium dioxide low concentration acid water treatment systems, with a total daily treatment capacity of 30000 m3, ensure that the external drainage meets the direct drainage discharge standard. As the landscape water of Xiaofu River in Zibo City, it is directly discharged into the river, while the external drainage of other chemical enterprises in Zibo City needs to be sent into the sewage treatment plant for secondary treatment.

Through long-term efforts, Dongjia has significantly reduced various consumption indicators of its products. It has reduced 328300 tons/year of waste water, 113.75 tons/year of sulfur dioxide, 23% and 48.9 tons/year of COD, with a reduction rate of 9.9%. Every year, 950500 tons of water, 1080160KWh of electricity and 149784 tons of steam are saved. The unit consumption of water, electricity and steam products has reached the advanced level in China, with remarkable economic benefits.

Through our continuous efforts, the quality of the exhaust gas and waste water discharged by the company is superior to the national emission standards. The company has successively won the honorary titles of "National Advanced Unit of Chemical Environmental Protection", "Advanced Unit of Environmental Protection", "Advanced Unit of Resource Conservation", "Environmentally Friendly Enterprise", etc. The company's existing "three wastes" emission will be one of the important bases for the national titanium dioxide industry to formulate standards
