A high concentration of catalytic oxidation of organic chemical wastewater treatment technology
The patent to the company 's own research and development process catalytic oxidation technology as the core , through treatment, catalytic oxidation, coagulation and sedimentation , biological oxidation steps , filters , etc. to complete the high concentration of organic chemical wastewater treatment.
The technology is in the presence of a catalyst , using an oxidizing agent at room temperature under normal pressure in the catalytic oxidation of wastewater contaminants , or direct oxidation of contaminants. Interrupting the process of degradation of organic molecules in the COD of the color chromophore such as azo , nitro, hydroxy sulfide , carbon alkylene group , etc., the purpose of bleaching , while effective to improve the BOD / COD value , making it easy biochemical degradation. The treatment process can be used alone , can be used in conjunction with biological treatment .
   This patented technology has been validated through years of practical operation of the various types of organic chemical wastewater treatment has a very good effect, the technology is mature , reliable, treated wastewater discharge can fully meet the state standards . Other treatment methods with the same industry , such as incineration , supercritical temperature and high pressure hydrolysis treatment, chlorine dioxide catalytic oxidation technology , biological treatment compared to other treatment methods have good effect , leading technology , low processing costs , no safe production risks and other features and advantages .

2 tar residue recovered toluene diamine (TDA) from the synthesis of tolylene diisocyanate (TDI) Emission patent
TDI residue itself as a tar condensates, condensates of TDI and TDA is the main chemical composition of the N, C, H, O. TDI production process, each producing 100 tons of drugs produced three to five tons TDI residues . Currently TDI production companies in the world to deal with the main incineration . The treatment process will generate a lot of harmful emissions, waste of resources, but also pollutes the environment. My company developed the patented technology in one fell swoop overcome the TDI process waste handling problems, to fill the international TDI residue treatment process technology gaps .
The patented technology , mainly through several steps waste pretreatment, hydrolysis reaction , the residue separation, distillation purification , effectively TDI production process of purification of waste TDA, a significant reduction in tar waste generation. Recycling can achieve 70% -90% TDA tar slag from TDI and TDA as a raw material for the production of TDI , TDI again back to the production process used to achieve the waste recycling. TDI in greatly reduced production costs , but also to achieve the industrial waste recycling , energy conservation and environmental protection purposes , has a huge space for development TDI production industry in the world .
