The construction of urban sewage treatment facilities is also one of the key tasks. According to the "Planning", during the "Twelfth Five-Year Plan" period, 160,000 kilometers of new supporting pipe network will be built, the daily sewage treatment capacity will be 42 million tons, the daily sewage treatment capacity will be 26 million tons, and the new recycled water utilization capacity will be 27 million tons/day. . Accelerate the construction of urban domestic garbage treatment and disposal facilities and strengthen the disposal of landfill leachate. During the “Twelfth Five-Year Plan†period, the chemical oxygen demand and ammonia nitrogen reduction capacity were increased by 2.8 million tons and 300,000 tons respectively. According to the "Planning", the investment demand for the "12th Five-Year Plan" energy conservation and emission reduction plan is 2.366 trillion yuan. Among them, the key projects for energy conservation, key projects for emission reduction and key projects for circular economy were 982 billion yuan, 816 billion yuan and 568 billion yuan respectively. The funds required for energy conservation, circular economy, industrial pollution prevention and control of key river basins, and flue gas desulfurization and denitrification projects are mainly solved by enterprises through their own funds, financial institution loans and social funds. Governments at all levels arrange certain funds to support and guide them. The main responsibility of urban domestic sewage treatment facilities and supporting pipe network construction is the local government, and the state gives appropriate support to key construction projects.
Diamond Wire For Silicon Cutting
The advantages of Diamond Wire cutting technology are huge, and it can replace the traditional mortar wire. Diamond wire is mainly used in the cutting of hard and brittle materials such as crystalline silicon and sapphire. Compared with traditional mortar steel wire cutting, it has high efficiency (4-5 times the cutting speed), less loss and high chip yield (15-20% more silicon). The advantages of low environmental pollution (no organic liquid) and high product quality. Among the diamond wire, electroplated diamond wire is widely favored by the market for its outstanding advantages of low wire consumption per piece, small wire diameter and high cutting efficiency, and is superior to resin diamond wire.
