Environment-friendly water treatment system for surface treatment production line

Abstract

The invention relates to an environment-friendly water treatment system for a surface treatment production line. The water treatment system comprises a sand carbon filter device, a first water storage tank, a filter, a reverse osmosis filter device, a second water storage tank, an ion resin filter device, a third water storage tank, a plurality of water pipes and a plurality of high-pressure pumps, wherein municipal water supply source enters the sand carbon filter device for sand carbon filter treatment and then the treated municipal water supply source enters the first water storage tank for storage; the reverse osmosis filter device carries out reverse osmosis filtration on water and then the treated water enters the second water storage tank for storage; and the ion resin filter device carries out adsorption treatment on positive ions and negative ions in water and then the treated water enters the third water storage tank for storage. The water treatment system is reasonable in overall structural design; the municipal water supply source is subjected to filter treatment through the sand carbon filter device, the reverse osmosis filter device and the ion resin filter device separately and the water used when different products are electroplated on 20-100PPM water supply production lines of different qualities, so that the electroplating quality is improved, the water treatment system has energy-saving and environment-friendly effects, the waste of excessive water is avoided, the emission and discharge amount can be reduced and the operating requirements are met.

Description

technical field [0001] The invention relates to the field of production water treatment, in particular to a water treatment system for an environmental protection surface treatment production line. Background technique [0002] In the electroplating industry, in order to continuously improve the quality of electroplating products, people often focus on the research of electroplating technology and the development and improvement of electroplating chemicals, but often ignore the importance of water. In fact, many of the poor quality of electroplating are due to the use of substandard quality. The existing electroplating water often uses hard water such as tap water or underground water. During the electroplating production process, the following hazards will occur: First, if the water used before the degreasing and degreasing agent processing is hard water, the product will be degreased and degreased Residual soap base is easy to be produced on the back surface, and soap base...

[0002] In the electroplating industry, in order to continuously improve the quality of electroplating products, people often focus on the research of electroplating technology and the development and improvement of electroplating chemicals, but often ignore the importance of water. In fact, many of the poor quality of electroplating are due to the use of substandard quality. The existing electroplating water often uses hard water such as tap water or underground water. During the electroplating production process, the following hazards will occur: First, if the water used before the degreasing and degreasing agent processing is hard water, the product will be degreased and degreased Residual soap base is easy to be produced on the back surface, and soap base and calcium Ca magnesium Mg ions in the water form metal saponification, which will cause pitting and fogging of the back coating when it is attached to the surface of the product; the second is that there are different impurities in hard water, Impurities will pollute the plating tank, making it difficult to clean the plating tank, and hard water contains too much calcium and magnesium ions, which will easily produce grains and precipitation after being brought into the plating solution. Cause poor electroplating; Third, the cleaning water quality requirements of many workpieces are very high, and there are too many hard water impurities to meet the requirements
