Abstract

The invention discloses a system for recovering heavy metals and recycling wastewater through treating metal wastewater by using a tube type filter membrane method. The system comprises a raw water collecting tank, a PH regulating tank, a concentration box, a micro-filtration membrane device, a micro-filtration water producing box, a carbon filer, a fine filter, a high-pressure pump and a reverse osmosis device which are sequentially communicated through pipelines, wherein the concentration box is also sequentially communicated with a sludge concentration tank, a sludge pump and a filter press through a pipeline. The system has the capacity of filtering particular pollutants without leaking sludge particles; a micro-filtration membrane can be cleaned with an acid agent, an alkaline agent, a bleaching agent and an oxidizing agent; and a membrane tube of the micro-filtration membrane is durable and has long service life. The system has the advantages that the process is simpler, more convenience is brought in operation, automatic control is easily realized, the occupation area is small, the investment of a foundation building period can be saved, the agent input can be reduced, the micro-filtration membrane can recover 99.9 percent of heavy metals, and is the best choice of recovering the heavy metals from the wastewater containing heavy metals.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a heavy metal recovery and waste water reuse system for treating heavy metal waste water by a tubular microfiltration membrane method. Background technique [0002] The composition of electroplating wastewater is very complex. The traditional chemical method of electroplating wastewater reuse and metal recovery adopts the process of chemical precipitation and reclaimed water reuse. Due to the recovery of heavy metal ions in wastewater, wastewater containing heavy metals needs to be collected and treated separately. Then reuse the reclaimed water. However, if the traditional chemical precipitation method is used for treatment, it is necessary to set up a sedimentation tank. Considering that the sedimentation water cannot completely remove the suspended solids SS and heavy metal suspended solids in the water quality, and after the precipitation, a quartz sand ...
