Abstract

The application discloses an energy-saving water-driven enhanced nitrification secondary treatment type biological turntable. The energy-saving water-driven enhanced nitrification secondary treatment type biological turntable comprises a reaction tank and a high water tank arranged above one side of the water tank, wherein a tank body comprises a middle water truck driving area and biological turntable areas distributed on two sides; a water truck and bio-discs connected coaxially are respectively arranged in the water truck driving area and the biological turntable areas; triangular effluent weir crests, guide plates and water distribution plates are arranged in the biological turntable areas; a plurality of right angle partition plates with are arranged on the circumference of the water truck at equal intervals to form water accumulating grooves; a water outlet tube is arranged in a position, lower than the water truck, of the water truck driving area. According to the energy-saving water-driven enhanced nitrification secondary treatment type biological turntable, the water accumulating grooves of the water truck use the right angle partition plates, the water truck is placed in the middle of the reaction tank, the discs are distributed on two sides, so that stress is more uniform, the torque is shorter, the resistance is smaller, the device rotation performance is improved, the oxygenation efficiency is improved, and the water truck loading padding in the water accumulating groove is driven by fist class treated effluent to complete the rapid nitrification.

Description

technical field [0001] The invention belongs to the technical field of water pollution control, and in particular relates to an energy-saving clean water driven enhanced nitrification secondary treatment type biological turntable. Background technique [0002] At present, China's urban domestic sewage treatment rate is already very high, but for rural domestic sewage, due to its scattered residence, weak economic foundation, lack of urban sewer pipes, sewage collection and centralized treatment are both economically and technically difficult to achieve. The centralized urban sewage treatment process with large scale, high energy consumption and difficult management, and the miniaturized, localized and decentralized sewage treatment process with low investment and fast implementation are more applicable. Therefore, it is of great significance to develop decentralized sewage treatment equipment with low energy consumption and easy management. [0003] Distributed rural domest...
