Abstract

The invention relates to a prefabricated reaction tank for the biological contact oxidation for the sewage pretreatment. The prefabricated reaction tank comprises a cylindrical tank body, a tank body top plate and a reversed cone-shaped sludge hopper, a partition plate is fixed in the cylindrical tank body to isolate the water inlet and the water outlet, a communication hole is formed on the partition plate, an aerator and a biological filler bracket are arranged at the bottom of the water outlet cavity side, biological filler is arranged on the biological filler bracket, a filler inlet is formed on the tank body top plate at the outer outlet cavity side, a manhole is formed on the tank body top plate at the water inlet cavity, the cylindrical tank body comprises a concrete core body with a steel cylinder, prestressed steel wires and a tank body protection layer, the outer wall of the concrete core body with the steel cylinder is wound with the prestressed steel wires to form a prestressed core body, and the tank body protection layer is fixed at the outer wall of the prestressed core body. The invention has scientific and reasonable structure design, short production period, low fabrication cost and high safety and reliability, can effectively shorten the construction cycle and reduce the construction cost, and has good corrosion resistance and long service life.

Description

technical field [0001] The invention belongs to the field of biological contact oxidation reaction tanks, in particular to a biological contact oxidation prefabricated reaction tank used for sewage treatment. Background technique [0002] With the rapid development of my country's economy, the process of urbanization is further accelerated, the scale of cities is expanding day by day, and the amount of sewage discharge is rising rapidly, which puts forward higher requirements for the capacity of urban sewage treatment. By the end of 2009, a total of 1,993 sewage treatment plants had been built in cities and towns across the country. The "Eleventh Five-Year" urban sewage treatment plan proposes that by the end of 2010, the urban sewage treatment rate will reach more than 70%, which has been achieved 1 year ahead of schedule. Biological contact oxidation is a biological treatment technology between activated sludge and biological filter, which has the advantages of both, and ...
