An In-situ Acid Wastewater Treatment Equipment for Laboratory

摘要

The random discharge status of acid wastewater in laboratory is a potential hazard to the municipal drainage system, wastewater treatment system and water resources. In this paper, an in-situ acid wastewater treatment equipment for laboratory is suggested. It is composed of an acid wastewater tank, an alkali wastewater tank, a neutralization tank, a washing gas box, pipes and other accessories. It can make the best use of the alkali wastewater produced in the laboratory to deal with the acid wastewater on site. The neutralization reaction takes place in the neutralization tank, and the solution reacted couldn't be discharged into the indoor drainage pipeline until its pH qualifies the standard. Through the sludge discharge pipe, the deposits can be collected individually, and then be hurtlessly treated and reused. Meanwhile, through the washing gas box the waste gas is decontaminated and discharged into atmosphere. So it can not only reduce the environmental pollution but also lower the treatment cost which corresponds with the idea of green laboratory. This equipment has the economical, practical, and workable property. Not only that, through a reasonable transformation, it is also suitable for other kinds of wastewater, so it has a certain technical populization value.
