For a long time, the environmental treatment pattern of "heavy sewage treatment and light sludge treatment" is gradually being reversed, and the market prospect of sewage sludge treatment equipment is broad. From then on, "trail muddy water" will become a full meaning of "gold content".
Sewage sludge incineration leads to a large market
Industrial wastewater sludge, urban sewage sludge, tap water sludge, rivers, lakes, reservoirs, dredging sludge, and even sludge generated after oilfield operations need to be treated. At the end of 2010, the Ministry of Environmental Protection issued the "Notice on Strengthening the Prevention and Control of Sludge Pollution in Urban Sewage Treatment Plants", which requires that new, reconstructed and expanded sewage treatment plants should plan, construct and operate sludge treatment facilities at the same time; sludge treatment is not currently available The capacity of the sewage treatment plant should be completed and operate the sludge treatment facilities within 2 years. The notice also proposed a mandatory index that the sludge must be dehydrated to a moisture content of less than 50%. According to the "Technical Guidelines for the Preparation of Major Pollutants Total Control Plan for the Twelfth Five-Year Plan" (draft for comments), the safety of sludge treatment will be given more attention during the "Twelfth Five-Year Plan", and it is planned to require sewage treatment of 100,000 tons per day All plants should be treated with sludge innocuous treatment. By 2015, the national sludge innocuous treatment rate will reach 50%.
The current sludge treatment methods mainly include land use, landfill, incineration and sea discharge. Sludge incineration technology has the characteristics of "reduction, stabilization and harmlessness", and has gradually become the mainstream of sludge treatment. The core consumables for sludge treatment are flocculants during pretreatment and play the role of concentration and dehydration; the core equipment includes sludge dehydrators, fluidized bed incinerators, biogas generators, sludge dryers, etc. Listed companies in the A-share related sludge treatment equipment category include: Huaguang, Zhongke General, Xingyuan Filtration, Tiantong, and Combustion Technology.
Diaphragm manufacturing companies have great potential
Similarly, the wastewater treatment equipment market has huge growth potential. According to the Ministry of Environmental Protection's Environmental Planning Institute, in the next five years, China's cumulative investment in sewage treatment will reach 1.06 trillion yuan, of which urban sewage treatment investment will reach 459 billion yuan, and industrial sewage treatment investment will reach 435.5 billion yuan.
MBR membrane technology is recognized as one of the most advanced and efficient wastewater treatment and resource utilization technologies in the world today, which is very suitable for the requirements of improving the level of water pollution treatment and promoting water recycling in China. During the "Twelfth Five-Year Plan" period, there is huge room for development of MBR technology. Among the A-share listed companies, Bishuiyuan, Nanfang Huitong and Xingrong Investment are all engaged in MBR biofilm manufacturing.
The Ministry of Environmental Protection also proposed in the "Technical Guidelines for the Preparation of Total Pollutants Total Control Plan for the" Twelfth Five-Year Plan "(draft for comments)" that during the "Twelfth Five-Year Plan" period, more than 160,000 kilometers of supporting pipeline networks must be built to achieve The average load rate of sewage treatment facilities is increased to more than 80%. In August this year, the Ministry of Finance has allocated 4.39 billion yuan in infrastructure expenditure budgets in the 2011 central budget for the construction of urban sewage treatment facilities and sewage pipe networks in 30 provinces (autonomous regions and municipalities) in Hebei, Zhejiang, Sichuan, Qinghai The project supports the improvement of environmental quality, ensures the safety of drinking water for the masses, and promotes the comprehensive, coordinated and sustainable development of the economy and society. At present, the listed companies involved in the construction of pipe networks in A shares include Nachuan, Weixing New Materials, Xinxing Casting Pipe, Qinglong Pipe Industry, Guotong Stock, etc.
