Problems solved by technology
However, the use of chemical methods often brings secondary pollution, and the cost of biological treatment is relatively high, and the subsequent separation of heavy metal ions is also relatively complicated. Therefore, the use of physical methods to recover heavy metal ions in sewage has become a research direction. ; At present, the devices used by some enterprises are not obvious enough to purify sewage, and the purification speed is also slow. It is difficult to meet the requirements of sewage treatment in actual use. Therefore, we propose a sewage treatment device

The invention provides a sewage treatment device for recovering heavy metal ions, which belongs to the technical field of sewage treatment. Through holes are evenly distributed on the surface of the separator; an ion filter device is provided at the water outlet, and a positive plate is provided at the top of the sewage chamber , there is a push plate on the negative electrode adsorption plate, the push plate is slidably arranged on the slide rail, the right side of the push plate is connected with a telescopic rod, the telescopic rod runs through the side of the adsorption chamber and is connected to the hydraulic cylinder; the right end of the outlet pipe is provided with a spray The condensing chamber is arranged on the right side of the inner cavity of the secondary recovery box; the device of the present invention is provided with a negative electrode adsorption plate at the bottom of the adsorption chamber, so that the heavy metal ions in the sewage move towards the negative electrode adsorption plate, and pass through the baffle The leakage hole of the plate is adsorbed on the negative electrode adsorption plate; there is an ion semi-permeable membrane in the filter device, which can filter out heavy metal ions; the device has the characteristics of simple manufacturing process, strong practicability and good recovery effect of heavy metal ions.
Description
technical field [0001] The invention relates to an environment-friendly purification facility, in particular to a sewage treatment device for recovering heavy metal ions. Background technique [0002] With the development of modern society, the amount of sewage containing heavy metal ions is increasing. Because heavy metal ions are difficult to degrade under natural conditions, they will not only pollute water sources, soil and other environments, but also cause pollution through the enrichment of the food chain. Finally enter the human body, thereby causing harm to human health, so it is particularly important to treat sewage containing heavy metal ions; existing methods for treating sewage containing heavy metal ions include traditional physical methods and chemical methods, as well as new biological methods processing method. However, the use of chemical methods often brings secondary pollution, and the biological treatment method has high treatment costs, and the subseq...
