Customer Profile: Starting from the production and manufacturing of power batteries, Tian * is committed to becoming a leading global provider of green energy system solutions. Its core businesses include new energy battery systems, resource recycling, and modern service industries. Listed in both Hong Kong and Shanghai, it is the first company in the industry to have "A" and "H" dual listed brands. Vietnam, as one of the most dynamic markets in Southeast Asia, has enormous development potential and unlimited market opportunities. Tian * has established its first overseas manufacturing base (Phase I) in Rong City, Nghe An Province, Vietnam. The wastewater treatment of this project is designed, procured, guided for installation and commissioning by the Baihuipu team. This phase brings us the sewage treatment system we designed.

        Project Name: Tian * Holdings Group

        Project Name: Tian * Lead Acid Wastewater Project

        Project scale: 2 tons/H lead-acid wastewater

        Run time: 2023

        Main process:Chemical precipitation ion exchange neutralization

        Processing standard:Meet industry emission standards

          Project features: This process has low cost, stable project operation, high degree of automation, system effluent lead ions<0.1ppm, cadmium ions<0.01ppm, stable compliance with local emission standards, allowing customers to rest assured about environmental emissions and focus on production.

        Tian * mainly produces lead-acid batteries, which generate a large amount of lead-acid wastewater during the production process. Lead acid batteries have the advantages of reversibility, stable voltage characteristics, large discharge capacity, and low cost, and are applied in various fields of the national economy. However, in their production process, the coating process, chemical conversion process, and battery cleaning process will generate heavy metal wastewater containing lead. Unlike biodegradable organic pollutants, lead is highly toxic and easily accumulates in organic organisms, causing fatal damage to human health. Therefore, if these lead containing wastewater are not treated or treated improperly, they will cause great harm to society and the environment.

        Based on water sample testing and specific customer requirements, we have designed an efficient solution for them: lead containing wastewater is regulated by a regulating tank to adjust the water volume and quality, and then pumped to a neutralization reaction tank. The neutralization reaction is used to remove lead, which involves the neutralization reaction between alkali solution and lead ions to produce lead hydroxide precipitate; Then pump it into the coagulation sedimentation tank, add polyaluminum chloride and polyacrylamide, and further remove the remaining lead; Afterwards, lead containing compounds are removed by an activated carbon adsorption device, and the effluent is discharged into a clean water tank for reuse.

        The treatment effect is as follows: After chemical precipitation ion exchange combined treatment, multiple sampling tests were conducted on the treated wastewater, and the results showed that the lead ion concentration remained stable between 0.5-0.8mg/L, far below the discharge standard of 1mg/L. The lead ion removal rate reached over 99.9%. After neutralization treatment, the pH value of the wastewater remained stable within the range of 6-9, meeting the discharge requirements of the environmental protection department for wastewater pH. The final project acceptance showed that the lead content increased from 10mg/L in the incoming water to 0.05mg/l, and the effluent was stable.

        The battery lead-acid wastewater treatment system we designed for Tian * effectively removes lead ions from the wastewater through reasonable process design, regulates acidity, and properly treats sludge and recovers resources.

        Looking towards the future, Baihuipu Environmental Protection will continue to adhere to the development direction of domestic and international markets, and further accelerate the pace of internationalization. At the same time, actively respond to the national "the Belt and Road" initiative, participate in the "the Belt and Road" construction, gradually deepen the overseas business layout, and further enhance the company's international brand influence.

        Chinese companies investing and building factories in Vietnam are willing to entrust their projects to us. We believe that service is a very important aspect, as our technical strength helps us enter the market, while our service attitude helps us stay on for a long time. Baihuipu Environmental Protection is also willing to spend time and energy exploring unknown industries, conducting experiments, making investments, ultimately accumulating experience, solving customer problems, and creating value.
