Lead is a widely distributed element in nature and one of the elements commonly used in industry. Lead and soluble lead salts are toxic, and lead-containing wastewater is a serious hazard to human health and animal and plant growth. According to reports, lead loss is 4.54-6810mg for every battery produced, followed by the petroleum industry to produce gasoline additives. The lead content in wastewater exceeds the national standard by a hundred times, posing a great threat to groundwater sources. If it is not treated, it will inevitably bring great harm to the environment and society. The use of ion exchange to treat lead-containing wastewater has a good lead removal effect, and industrial lead-containing wastewater can achieve discharge up to standard, with little harm to environmental pollution. The ion exchange resin has a long service life and can be repeatedly used for regeneration. Suzhou Bojie Resin Technology Co., Ltd. provides lead removal resin, which has the advantages of high selectivity, easy adsorption and desorption regeneration, reusable, good controllability and simple operation, especially suitable for the treatment of lead-containing wastewater.
