There are dozens of workshops, and many different products are produced there. How should the amount of wastewater generated and its composition be measured in order to determine the most appropriate treatment process?
After mixing the wastewater, conduct a test. With the test report, we can finalize the plan.
Have you heard the saying that one bad element can ruin the whole batch? Perhaps the other waste streams are relatively simple and can be treated for 10 yuan per ton, but when such difficult-to-treat waste is mixed in, the cost of treating all the waste increases, resulting in significant financial losses. It’s necessary to analyze the composition, volume, and frequency of each type of waste in order to design an appropriate treatment solution
Why can’t wastewater that is easy to treat be discharged into water that is difficult to treat? For dilution purposes, isn’t that more urgent and cost-effective? Each stream can be equipped with a set of environmental protection devices; that’s also an option, if you have the money!
Dilution should be done after treatment. Not every stream goes to the treatment device; rather, each stream of water needs to be analyzed and separated. Those with similar treatment methods are combined together, while those with significant differences in costs are treated separately. For example, some wastewater can be discharged after simply being neutralized, while for certain toxic heavy metals that are under close monitoring, even a small amount of these substances requires treatment through evaporation. The cost difference is enormous; in such cases, there’s no time to concentrate the waste – dilution is necessary. It’s important to consider practical circumstances; one can’t just rely on what they’ve read from books
What you say does make sense indeed; you have thought it through deeply, while I have only considered it superficially.
