Abstract
The invention discloses a heavy metal adsorption waste water treatment device. The device comprises a pretreatment device and an adsorption device. The pretreatment device is connected to the adsorption device. The pretreatment device comprises a pH adjustment system. The pH adjustment system comprises a metering pump, a pH analyzer and an automatic control module. The metering pump is connected to the automatic control module. The automatic control module feeds a signal back to the metering pump. The adsorption device comprises a first-grade adsorption treatment device, a deep adsorption treatment device and a stand-by adsorption treatment device. The first-grade adsorption treatment device is located in front of the deep adsorption treatment device. The stand-by adsorption treatment device is connected to the rear of the deep adsorption treatment device. Auxiliary equipment is connected to the rear of the stand-by adsorption treatment device. Through the device, sewage can be neutralized and degraded. Stone granules and active carbon in the first-grade adsorption treatment device can filter suspension particles in the sewage. The sewage is further filtered through deep adsorption treatment.
