A project of Shenmu Coal Chemical Tianyuan Company won the third prize of the 2022 Shaanxi Province Innovation Method Competition

Recently, the final results of the "Qin Chuangyuan Jinghe Cup" 2022 Shaanxi Province Innovation Method Competition were released
.
Shenmu Coal Chemical Tianyuan Company's project of "a method for removing COD from coal tar deep processing wastewater" won the third prize
.

The 2022 Shaanxi Innovation Method Competition is co-hosted by Shaanxi Science and Technology Association, Provincial Department of Science and Technology, Provincial State-owned Assets Supervision and Administration Commission, and Xixian New Area Administrative Committee, with the theme of "Strengthening Innovation Self-confidence and Promoting Self-reliance and Self-improvement", including the practical application
of technological innovation methods, management innovation methods and other innovative methods in R&D, production and learning life.

Tian Yuan Company's "a method for removing COD in coal tar deep processing wastewater" takes biochemical effluent as the research goal, upgrades the traditional coagulation precipitation to magnetic coagulation precipitation, and uses the loaded metal oxide activated foam carbon for catalytic ozone oxidation treatment of wastewater, and the wastewater after joint process treatment can meet the standard
of circulating cooling water reuse.
This method takes "turning waste into treasure" as the research idea to realize the high-value utilization of
low-value resources.
Through the joint treatment process, the defect that the wastewater treatment process in the existing technology can only meet the wastewater discharge standard and cannot be recycled, so as to realize the recycling of water resources in the process of coal grading and grading production
.

It is understood that in 2016, Tian Yuan Company built a 100 tons/hour coal tar lightweight wastewater treatment project relying on the self-developed high-concentration organic wastewater treatment technology, using the three-stage treatment process of "pretreatment + biochemical treatment + advanced treatment" to effectively reduce tar, ammonia nitrogen, phenolic solid suspended solids, etc.
in wastewater, and the treated reuse water is used as circulating water supplement water and quenched water to achieve reclaimed water reuse and zero discharge of industrial sewage, and produces clean blue charcoal that can be used for civil scattering and smog control with indicators better than anthracite.
It has significant social benefits and the demonstration and leading role
of blue charcoal clean production.
In 2017, "Tianyuan brand blue charcoal" was recognized as "Shaanxi Famous Brand Product"
