■1.4 Technology Introduction
TRHJ-WGT series products integrate various treatment equipment such as pretreatment equipment, biological oxidation treatment equipment, enhanced treatment equipment and terminal treatment equipment, and fully consider the process advantages and equipment structure of each treatment equipment, and combine each process into an organic whole. The whole equipment is divided into pretreatment section, biological treatment section, enhanced treatment section and post-treatment section.
Pretreatment process: Usually, alkali washing spray is used in the first stage process, and water washing spray, oil washing spray, inorganic oxidation solution spray and so on can be used according to the actual situation. The main function is to absorb particulate matter, waste gas components, water-soluble or oil-soluble organic matter in waste gas through the action of gas-liquid countercurrent contact, mass transfer absorption, acid-base neutralization reaction and other processes. Excessive changes in the exhaust gas environment will have some adverse effects on the biological deodorization process in the second stage. Therefore, the role of the pretreatment process is to create a good and stable working environment for the microbial process in the back stage.
Biochemical oxidation treatment process: Biotrickling filtration treatment process is usually adopted. The packing layer in the box can not only increase the contact area of the two phases and make the two phases fully dispersed, but also be used for the attachment and reproduction of dominant biological strains. In the biological reaction section, the strains usually consist of desulfurization bacteria and nitrifying bacteria in a two-stage reaction chamber.
Strengthening treatment process: Microwave plasma photocatalytic oxidation technology is usually adopted in strengthening treatment process. In this stage, microwave plasma and electrodeless ultraviolet light catalytic oxidation technology are adopted, and the malodorous substances are degraded by enhanced oxidation of microwave plasma and photocatalysis of microwave plasma. Advanced oxidation processes such as photocatalytic oxidation, high-energy ion oxidation, ozone oxidation and heterogeneous catalytic oxidation can also be adopted according to the actual situation.
Post-treatment process: the post-treatment process usually adopts adsorption, adsorption and desorption, catalyst incinerator (CO), direct waste gas combustion furnace (TO) and other treatment processes.
■1.5 Function introduction
This equipment is highly integrated. When the equipment leaves the factory, all parameters have been adjusted to the best according to the field working conditions. For example, when the water level in the equipment is too low, the equipment will automatically start the water supply system, and when it is too high, the drainage system will be opened; when the ambient temperature is too low, the equipment will automatically start the heating system and automatically adjust the temperature inside the equipment to an appropriate temperature. Users only need to connect water, electricity and gas after the equipment is in place, and then press the start button.
Replenishing water: It is recommended to use soft water and tap water unconditionally;
Drainage: it is recommended to connect to the regulating pond, which can be connected to the sewage pipe network unconditionally;
Electricity: 380V，50Hz， three-phase four-wire
Compressed air: 0.7MPa，0.5m³/min（instantaneous）
