Electroplating wastewater treatment equipment integration

Electroplating and metal processing industrial waste water is the major source of zinc plating or pickling liquid entrainment. Pollutants through the metal rinsing process has shifted to the rinse water. The wastewater contains large amounts of hydrochloric acid and zinc, copper and other heavy metal ions and organic brighteners, high toxicity, and some also contain carcinogenic, teratogenic, mutagenic toxic substances, great harm to humans. 1, the central processor
Neutralization reaction and solid-liquid sandblasted tungsten target unit is a core part of the whole treatment process, the reasonable control of the pH value of Zn2 + to form Zn (OH) 2 precipitation, and solid-liquid separation is to ensure thorough discharge of the key. The unit consists of grille, regulation pool, and the reaction composition sedimentation tank, dosing system uses a multi-in-one design of dosing equipment, mainly by dosing bucket, metering and control system, automatic control and manual control two kind of switching mode, both to ensure the best conditions for the precipitation reaction, and easy to operate, simple and convenient, automatic adjustment of dosing to ensure the accuracy of the dosage required to maintain a stable pH. Prepared Na (OH) solution from entering the lift pump self-priming and response sedimentation tank. Process is simple, easy to operate and flexible, practical province strong, water quality is stable and reliable, low operating costs. reuse treatment device
Electroplating wastewater reuse Tungsten eletrode device includes reverse osmosis membrane filter, pressure pump, control instrumentation. Membrane cleaning part by the water tank and circulation pump and other components. This section is used to clean the membrane residual Zn (OH) 2 precipitates, to prevent membrane clogging.demonstration: Membrane electroplating wastewater treatment technology as a high-tech wastewater treatment and reuse technology, electroplating industries for the promotion of clean production has played an exemplary role.
