The pollution concentration of washing wastewater from PCB manufacturers is very low, and some tank solutions have relatively high pollution concentrations, such as ink waste liquid, fluffing agent waste liquid, etching waste liquid, etc., because of the existence of these high-concentration waste liquids, many people It is believed that these waste liquids represent the pollution level of circuit board enterprises. In fact, the waste tank liquid of circuit board companies is precious. In addition to the heavy metals in it, other chemicals are a very important source of cost savings for circuit board companies. If the government allows companies to recycle and recycle waste tank liquids, then circuit board companies will no longer have a reason to be a polluting company.
