Abstract

The invention relates to a heavy metal wastewater filtering device which comprises a first feeding port, a feeding pump, a pretreatment device, a pressurizing device and a cleaning tank. The pretreatment device comprises a pressure gauge arranged above, a second feeding port is formed below the pressure gauge and communicated with an adsorption device, the adsorption device is communicated with a pH adjusting device, the pH adjusting device is located below the adsorption device, and a liquid outlet is formed in the bottom of the pH adjusting device. The adsorption device is sequentially provided with a first cavity, a first adsorption layer, a second cavity and a second adsorption layer from top to bottom. The adsorption device is provided with a connecting pipe, and the connecting pipe sequentially penetrates through the first cavity, the first adsorption layer, the second cavity and the second adsorption layer from top to bottom.

Description

technical field [0001] The invention belongs to the field of heavy metal wastewater treatment, and relates to a heavy metal wastewater filtering device and a process method. Background technique [0002] General mining, machinery manufacturing, chemical industry, electronics, instrumentation and other industrial production processes produce a large amount of wastewater containing heavy metals, generally including toxic heavy metals such as septum, nickel, mercury, zinc, etc. Heavy metal wastewater is more harmful to environmental pollution and human life. One of the largest industrial wastewater, the heavy metals in the wastewater cannot be decomposed and destroyed, and can only be treated by transferring the existing position and changing its physical and chemical form. Generally, the methods for treating heavy metal wastewater include chemical precipitation method, ion exchange method, etc. After treatment, the heavy metals contained in reclaimed water are lower than the d...
