Shandong mining mining solution to a mining solution Yantai, Shandong Mining Group, washing the sewage treatment has been very poor, one is the high cost of sewage treatment, and second, the effect of sewage treatment is not good. Finally, the person in charge of environmental protection at the mining site contacted us by visiting our website www.ggmyjs.com and we experimented with the sewage water provided by the mining industry and started to work out a plan. Source of filtered water that do a good job in water treatment, we must emphasize the "three points seven management" concept, but the process management is very important, but the fundamental problem is the agent, if the beginning of the pharmaceutical selection error, the polypropylene The amide cation is used as an anion or the content of polyaluminum chloride is mistaken. This is not responsible for enterprises, not only cause environmental pollution, but also increase business costs. Not only lost customers, their own company's reputation will also adversely affect the water treatment industry. We conducted a number of exhaustive experiments on the water samples provided. Finally selected a good treatment, but also relatively low cost pharmaceutical solutions. Send a sample on June 3 for a pilot test. Results of the pilot test results are not good test. The rapid communication between the two sides to find out the reasons for the study, concluded that: the selection of water treatment chemicals no problem, the root cause of poor treatment is sent to each other when sending is to add sewage water samples, our technicians based on experimental data And experience, adjust the addition of PAC and polyacrylamide, put into operation again, and finally achieved the desired effect. After a week of trial, we finally signed a long-term cooperation agreement with Yantai Mining. After this time we technicians have learned an experience, before making a water sample to the customer to confirm whether the water sample is the original water sample. This is also very important. After a month of cooperation, customers are very satisfied with the sewage treatment, reducing the cost of 3/1 than before, and can discharge standards.
