In recent years, the Chinese government has issued a number of policies to guide the prevention and control of water pollution. Especially since the release of “Water 10” in April 2015, the intensive introduction of relevant industry policies has provided a good policy environment for the industrial waste water treatment industry. At the same time, after the state has issued new standards for industrial pollutant emissions, it is difficult for traditional treatment technologies to adapt to new emission requirements. Therefore, "industrial waste water treatment technology" has become the key to the survival of polluting enterprises.
China has issued more than 10 relevant standards for industrial waste water treatment industry, more than 30 national environmental standards for water pollutant discharge, and more than 20 local environmental standards for water pollutant discharge for standard indicator industry development. The market scale of industrial waste water treatment industry consists of industrial waste water engineering investment and industrial waste water treatment operation services. In 2016, China's industrial waste water treatment industry market size was 84.284 billion yuan, an increase of 4.86% year-on-year; China's industrial waste water treatment is expected from 2017 to 2020 The industry market capacity will reach 380 billion yuan. From the perspective of sub-sectors, the market scale of industrial waste water treatment operations of ferrous metal smelting and rolling processing industry, chemical raw materials and chemical products manufacturing industry reached more than 10 billion yuan, accounting for 17.5% of the total industrial waste water treatment and operation market.
The market size of China's industrial waste water treatment industry is mainly concentrated in East China and Central South China. The market size is 36.209 billion yuan and 17.514 billion yuan respectively, accounting for 42.96% and 20.78% of the national market respectively, accounting for 73.7% of the total.
Because many industrial waste water components are complex and of various nature, there are still some technical problems that have not been completely solved. Industrial waste water treatment has always been a weak link in the water pollution prevention and control chain. There are market competition irregularities, weak technical strength, and serious local protectionism. Industry development depends on issues such as policy support. At present, the development of efficient and low-cost refractory waste water technology has always been the focus and direction of industrial waste water treatment development. The research and development of industrial waste water treatment industry mainly includes: iron-carbon micro-electrolysis technology, high-gradient magnetic separation technology, super critical water oxidation technology, high-salt water treatment technology, and centralized treatment technology for waste water. Major companies have a certain market representation in specific segments. According to statistics, there are more than 300 sewage treatment enterprises above designated size in China, which constitute the main supplier of industrial waste water treatment industry. There are a large number of enterprises in China's industrial waste water treatment industry, and most of the enterprises engaged in engineering design and construction, but most of them are small in scale, industry concentration industry, and industry competition is scattered. The average processing cost of China's industrial waste water industry is on the rise, rising from 1.26 yuan/ton in 2011 to 1.6 yuan/ton in 2016, with an average annual compound growth rate of 4.88%. From the perspective of sub-sectors, the average treatment cost of waste water ranges from 0.55-6.98 yuan/ton. Among them, the average processing cost of gas production and supply, furniture manufacturing, electrical machinery and equipment, manufacturing, automobile manufacturing, petroleum processing, coking and nuclear fuel processing, computer, communications and other electronic equipment manufacturing industries is 5 yuan / ton or more.With the improvement of industrial waste water discharge standards, the demand for industrial waste water treatment will continue to grow. The industrial waste water treatment industry will last in a favorable period of rapid development. Among them, industrial waste water treatment is a hot spot for industry development, while PPP mode will become an important development model of the industry.
