Problems solved by technology

This method has simple process, easy operation, and low construction and operation costs, but the disadvantage is that the pH range of the optimal precipitation of various heavy metal ions is different, and it is necessary to add drugs to the precipitation in stages. If complex ions are mixed in the wastewater, some Ions are difficult to meet emission standards
The ion exchange method is to use the exchange ions in the ion exchange resin to exchange some ions in the heavy metal wastewater to remove them, so that the wastewater can be purified. The disadvantage of this method is that the price of the resin is relatively expensive, and the operating cost is high. Difficult to regenerate, hard to handle concentrated water
Although there are various heavy metal removal methods in heavy metal wastewater, it is difficult to realize fully automatic wastewater purification. The reason is that the wastewater removal process and the preparation of the purification agent for wastewater removal are realized in two steps, so it is difficult to achieve full automation.

Abstract

The invention provides an electroplating wastewater treatment device. The electroplating wastewater treatment device can be used for organically integrating a purifier generation device and a wastewater treatment device, so that a whole process of preparing a purifying agent and treating wastewater is fully automatic; furthermore, the adsorption of suspended and turbid matters is also improved; anadsorption pile is arranged so that suspended matters of the wastewater are subjected to first-time filtering; a porous layer and a filtering layer are arranged in a process of permeating the wastewater from the bottom of an adsorption tank so that the suspended matters of the wastewater are subjected to second-time filtering and the adsorption effect of the suspended matters is improved.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to an electroplating wastewater treatment device. Background technique [0002] There are many methods for the treatment of heavy metal wastewater, such as alkaline precipitation, ion exchange, electrodialysis, reverse osmosis, electrocoagulation, etc. At present, the most widely used method is the alkaline precipitation method, which is a method of removing heavy metal ions by forming hydroxide precipitation only by adding alkali to adjust the pH value. This method has simple process, easy operation, and low construction and operation costs, but the disadvantage is that the pH range of the optimal precipitation of various heavy metal ions is different, and it is necessary to add drugs to the precipitation in stages. If complex ions are mixed in the wastewater, some Ions are difficult to meet emission standards. The ion exchange method is to use the exchange ions ...
