Abstract
The application discloses a kind of waste liquid processing device and waste liquid processing method.The device includes: wastewater treatment device body, water inlet pump, water inlet pipe, water outlet pipe, dissolved gas release system;Body includes central cylinder and outer cylinder, and both are communicated by communicating pipe up and down;The water inlet of waste liquid is opened on the side wall of central cylinder;Water inlet pump and water inlet pipe are connected with water inlet, so that the waste liquid injected through water inlet carries out cyclone reaction in central cylinder;Water outlet is opened on outer cylinder;One end of water outlet pipe is connected with water outlet, and the other end is connected with dissolved gas release system and communicated;Dissolved gas release system is connected with central cylinder, so that waste liquid dissolved with gas is injected into central cylinder again to carry out secondary cyclone air floatation reaction, and mixed cyclone reaction with injected waste liquid;Central cylinder top is connected with slag discharge pipe and exhaust pipe, so as to discharge dregs and waste gas.The application realizes the rapid gel breaking separation of operation waste liquid, shortens the processing flow, reduces the floor area and processing cost.
