Laboratory wastewater, regardless of the small amount, is more troublesome to deal with than industrial wastewater.Today is strong acid and tomorrow is strong alkali, heavy metals and organic solvents are mixed, and the composition changes ridiculously.Many people just look at the parameter table when they buy sewage treatment equipment, and they buy it back and run it to see if the test exceeds the standard.

Laboratory sewage discharge standards
GB 18466-2005.This is the standard of medical institutions.Laboratories in universities and scientific research institutes, many places implement the GB 8978 first-level standard, CODcr≤100mg/L, ammonia ≤15mg/L.If you allocate equipment according to medical standards, it will cost you money.According to the first-level standard, I'm afraid I can't carry it.I can't say which one to follow. Anyway, in the cases I have seen, there are three of the ten wrong standards.In March 2024. the chemistry laboratory of a university in the southern suburbs of Xi'an found me. They had previously spent 38.000 yuan to buy a so-called standard emission equipment. As a result, the Environmental Protection Bureau came for sampling. CODcr exceeded three times, and the total chromium also exceeded.A fine of 20.000 was imposed, and the equipment was disabled for rectification.I went to the scene and took a look. The equipment was a sedimentation tank with quartz sand filtration, and there was no activated carbon adsorption.To put it bluntly, that thing is a large water purifier. Do you use it to treat chromium-containing wastewater?Later, they replaced our DIEN's laboratory sewage treatment equipment with a complete set, with automatic dosing and online monitoring, real-time monitoring of pH, COD, and heavy metals, and re-inspection after three months, all of which met the standards.
What aspects do you need to see to buy sewage treatment equipment in 2026?
I just want to ask, did anyone tell you this when you bought the equipment?There must be an automatic dosing system. The composition of laboratory wastewater is the same every day, and you can't keep up with manual dosing.Online monitoring must be combined with dosing. Some manufacturers have installed a sensor as a decoration. The data is good-looking but not linked, which means it is not installed.The material must be corrosion-resistant. 316L stainless steel is the bottom line, and it will be perforated after two years with 304.All of our DIEN's equipment is standard, so you don't need to add money later.
