We developed a new generation of electronic effluent preparation copper sulfate basic technology, and the process is mainly to adopt synthesis of copper sulfate solution, adding a little crystal nuclei agent (the agent is no harm to the environment) to make products coarsening. This technology will no longer produce ammonia, and solve the problem of ammonia thoroughly, and the resulting product is like sand (good for cleaning and can improve its purity and production efficiency), with good quality, and the cost will be further reduced.

At the moment, ammonia problem has become the No. 1 control targets of environmental pollution, already over COD. During the fifth plenary session of the 12, the state clearly indicated that reduction target of ammonia emission was 10%. Existing copper ammonia solution or ammonia water preparation basic copper chloride technology is widely used due to the low-cost and high-efficiency. With the increasing pressure on the environment will gradually disappear. If not upgrade, it will be increasing pressure to survive. To recycle ammonia nitrogen, many companies are adopting ion exchange or concentrated and distilled crystallization, but effluent produced over 10 tons per ton of product, so the recovery cost is very high. The new preparation technology we have developed, not only solve thoroughly the problem of ammonia and ensured the quality of product, but also kept the technical characteristics of high efficiency and reduced costs further. It will be more popular.

The new technology, besides solving the ammonia problem, and further reduced the loss of raw materials. The copper content in the wastewater is reduced from 0.5% to 0.1%, and the raw materials consumption of copper can be reduced about 4%.

We have applied for patent protection for the technology, patent application number: 201210123599.9
