Abstract

The invention discloses a system and a method for treating organic wastewater of a circuit board. The system comprises circuit board processing equipment, a collection pool, a vibration film ultrafiltration device, a reverse osmosis device and an incinerator, wherein the vibration film ultrafiltration device comprises an enclosure, a membrane module and a motor, wherein the membrane module downwards extends to form a central rotating rod, therefore, swing can occur by using a centrifugal force generated by matching and utilizing the motor and a belt to drive an eccentric block on a central driving rod to rotate; energy generated by swing promotes the membrane module to vibrate through the central driving rod; and a shear force generated by high-frequency vibration is spread through a membrane surface in the membrane module in a sine force, thereby the silt of the membrane in the membrane module is effectively overcome and the simple and effective treatment of the organic wastewater ofthe circuit board is realized. The treatment system can be used for continuously and effectively separating clear solution from concentrated solution; the clear solution is input into the reverse osmosis device for RO (Reverse Osmosis) advanced treatment and then is recycled to the circuit board processing equipment, so that the cost is saved; and the concentrated solution is incinerated and treated by using the incinerator, and thus the goals of reducing emission and waste are achieved.

Description

technical field [0001] The invention relates to the technology in the field of wastewater treatment equipment, in particular to a circuit board organic wastewater treatment system and method. Background technique [0002] The organic wastewater of circuit boards mainly comes from chemical solutions containing higher concentrations of organic matter in production and subsequent cleaning water. Among them, the thick liquid produced by various inks (such as oil film, green oil, detergent, leavening agent solution and subsequent cleaning water, degreaser solution, glue removal solution, net room / screen printing, wash room washing liquid etc.) are the main sources of pollution. Its CODcr concentration is very high, generally reaching 3000-8000mg / L, which is a kind of seriously polluted wastewater. The traditional treatment methods mainly include chemical precipitation-ion exchange method, ion exchange-activated carbon and gaseous coagulation-filtration method. These methods can...
