Coking wastewater treatment process
Thread Content
Which are the main companies (including design institutes) that supply coking wastewater treatment systems? How is the actual operation in the project? Can it meet the emission standards?
There are many things that it’s simply impossible to clarify. Our company has two manufacturing facilities, and they possess the qualifications to carry out design and manufacturing work. In short, there are many such things. It depends on what you want to have done; currently, it’s the client’s market that dictates everything
It is very difficult to discharge coking wastewater using conventional biological treatment processes in accordance with **Grade 1 standards; it is hard to meet the requirements regarding ammonia nitrogen and COD levels. Advanced treatment steps are necessary after biological treatment, which in turn leads to a significant increase in treatment costs
The treatment process for coking wastewater must be considered systematically; the conditions of the previous process determine those of the subsequent one, and the specific treatment method for the wastewater is determined by the previous process. Only by controlling the quality of wastewater in the previous process within a certain range can the wastewater treatment process ensure that the treated wastewater meets the required standards. :P
If it’s a state-owned enterprise, things are better in such cases. Where I work on construction projects, I can’t say the same
It is not certain that passing each individual processing step will guarantee overall compliance; moreover, the quality of coking wastewater varies greatly depending on the degree of post-treatment in the coking plants. It is difficult to ensure that such wastewater meets all first-level standards without resorting to tertiary treatment. It seems that the person in Building 4# has a lot of experience; could we communicate via text message?
The quality of coking wastewater is unstable, and it is difficult to control the ammonia vaporization process in the presence of residual ammonia. COD is a significant problem; the short-chain substances generated during coal pyrolysis are soluble but difficult to biodegrade. The inlet water temperature is high, yet the water appears relatively clear; however, the color intensity of the effluent is higher than that of the inlet water. At present, it is challenging to meet the industry’s first-class standards for biological treatment of such wastewater, and more intensive oxidation treatment is required
Dear leaders: Instead of talking about the difficulties in treating coking wastewater, please first provide the analysis data on its components, and then we can work on finding a solution, okay? :lol
The coking wastewater treatment system in our facility was designed by Sand Company, and it meets the design requirements.
Generally speaking, state-owned enterprises are better at handling coking wastewater; in the treatment of such wastewater, every stage needs to be carefully controlled so that the final output meets acceptable standards
Beijing Sander Company is okay; you can check out their website.
