This is from a previous article. In view of the current situation of industrial wastewater treatment in China, Qingdao Aikang Ozone Generator shares this article again. There is public opinion that China, the world's most difficult industrial wastewater, is biased but not unreasonable. Over the past 30 years of reform and opening up, China's industry has developed rapidly. The wave of industrial transfer from developed countries has also come to China. The problem of three wastes caused by industry has squeezed the fragile ecological environment. What are the problems faced by industrial wastewater? The views and ideas of many experts and entrepreneurs in the field of industrial wastewater treatment, and discuss the technical development direction and business model of industrial wastewater treatment. In the survey, it was found that the difficulties of industrial wastewater treatment are due to technical and market factors, as well as macro environment and management. The main problems are as follows:
First, industrial wastewater treatment technology is particularly complex. There are many aspects that need to be considered in the selection process, including the production process of the polluting enterprise. Industrial wastewater treatment process is complicated, some enterprises lack of investment, can not treat wastewater well; Some enterprises do not invest enough, but due to poor management in the later period, the water does not meet the standards and cannot achieve the expected effect. The composition of industrial wastewater is complex, and unlike municipal wastewater, the technology is relatively simple.
Secondly, the technical level of industrial wastewater treatment is limited. From the current level of technology, many domestic industrial wastewater treatment theoretically does not meet the standard, and may be able to handle the test, but can not achieve real long-term stable operation. For example, pharmaceutical wastewater and sodium glutamate wastewater are difficult to treat, and the existing level of technology needs to be improved.
Third, China's economy is underdeveloped, not only the wastewater is difficult to treat, but also the high-yield sewage enterprises that have contributed a lot to the economy will continue to exist. As far as the pharmaceutical industry is concerned, many pharmaceutical factories in China are major drugs that contain a lot of pollution. Foreign pharmaceutical manufacturers buy these primary products and perform some chemical treatment to improve their efficacy. At this point, they produce less pollution and more value. However, China's pharmaceutical production technology is not so developed, can only "do stupid work", not only limited added value, but also cause environmental pollution.
Fourth, sewage treatment in industrial parks. The industrial park intends to centrally treat industrial wastewater, but new problems have arisen in actual operation. After the industrial wastewater is concentrated together, a public centralized sewage treatment plant is finally built, and the wastewater from each plant can enter the sewage treatment plant after a certain degree of treatment. Therefore, the pollutants that are easy to treat are treated by the factory itself, and most of the final pollutants are difficult to treat, which ultimately leads to the high operating load of the sewage treatment plant and the reduction of pollutants can not be achieved.
Fifth, the problem of "negative effects". Some polluting enterprises do not want to invest too much in wastewater treatment, profit-seeking enterprises will also exist such a concept, they think that the treatment of industrial wastewater in addition to meet the inspection of the environmental protection department to avoid being punished, and there is no benefit, but increase the cost. Industrial wastewater can not be effectively treated because of the enterprise's convenience.
Sixth, the problem of market chaos. The pollution control enterprises (environmental protection companies) that undertake industrial wastewater treatment projects are mixed, so vicious competition has formed in the industry, resulting in some enterprises that have been committed to the field of industrial wastewater transformation when they encounter opportunities.
Seventh, the problem of scale effect. The list of many industrial wastewater treatment projects is not large enough, and it is difficult to form scale effects and produce large enterprises compared with municipal sewage treatment. Although there are excellent environmental protection companies in this field, it is difficult to reach millions or even tens of millions of tons of daily treatment as municipal sewage treatment companies.
Eighth, the problem of business model. Every environmental protection company has a surprising way to survive, but the main model is still "design, procurement, construction", and other universally applicable business models are still exploring.
Ninth, zero emissions myth. China has been implementing zero discharge of industrial wastewater treatment for many years, but in fact, the true sense of zero discharge can not be done, and there is no perfect zero discharge case in our country at present. The misunderstanding of zero emission makes many enterprises blindly equipment and technology on this issue.
Tenth, emissions standards are difficult to implement and lax supervision. Lax supervision, "one-size-fits-all", and detachment from reality are the main reasons why some industry emission standards are difficult to implement, and the industrial wastewater treatment industry also has the same problem.
