How to treat acid-containing wastewater--besides neutralization
Thread Content
The company is looking for laboratories in the area around Beijing that deal with large amounts of acid-containing wastewater. The industrial park does not allow digging pits outdoors for neutralizing this wastewater; are there any other ways to treat it so that it can be discharged in compliance with regulations? I need the help of all the experts!
It depends on what kind of acid it is. It might be possible to use a MVR evaporation method, similar to those used in many wastewater treatment and recycling processes today; this would allow for the production of qualified wastewater on one hand, while also yielding acid of a certain concentration as a by-product. Of course, there may be specific requirements regarding the cost of corrosion protection for such equipment. ——It’s just my personal opinion; I’m not sure whether such an approach is feasible
Check for impurities; if they’re not particularly complex, the acid can be recycled
Send to the waste liquid or solid waste recycling center for treatment
Sell in small quantities; if the amount is large, handle it yourself – MBR will suffice
Laboratory waste liquids are classified as hazardous waste and must be disposed of by qualified manufacturers.
