Embodiment 1

[0019] Municipal sewage treatment tanks, such as figure 1 , figure 2 As shown, including the treatment tank 1, the sewage is regulated and stirred by the regulating tank and then enters the treatment tank 1 through the water inlet 15. The rear side wall of the treatment tank 1 is provided with a stirring device 2, and the stirring device 2 is fixed on the rear side of the treatment tank 1. The stirring shaft 21 on the wall, the stirring shaft 21 is provided with a stirring disc that can rotate around the stirring shaft 21, and the first stirring blade 22 and the second stirring blade 22 that can rotate around the stirring shaft 21 are successively fixed on the stirring disc around the circumferential direction of the stirring disc. Blade 23, the 3rd stirring blade 24 and the 4th stirring blade 25, the length of the 2nd stirring blade 23, the 3rd stirring blade 24 and the 4th stirring blade 25 are respectively 2 times, 3 times and 4 times of the length of the first stirring bl...

Abstract

The invention relates to the sewage treatment field, and especially relates to a municipal sewage treatment tank. The municipal sewage treatment tank comprises a treatment tank (1), the rear sidewall of the treatment tank (1) is provided with a stirring device (2), the stirring device (2) comprises four fixed stirring vales with different lengths, and the end portion of a fourth stirring vane (25) is provided with a baffle plate (250) vertical to the fourth stirring vane (25); and pebbles (3) are laid in the treatment tank (1). The municipal sewage treatment tank can realize irregular flow and full disorder of water in the treatment tank to guarantee full mixing of medicines added into the treatment tank and water, and also allows the pebbles with surface mycoderm under the treatment tank to contact with water above the treatment tank, so the decrease amounts of the chemical oxygen demand (COD) and the biochemical oxygen demand (BOD) of water increase, and carbon and phosphorus removal and nitrogen fixation effects are maximally achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an urban sewage treatment pool. Background technique [0002] With the growth of urban population in our country, the expansion of residential areas and the further concentration of population, domestic water consumption has also increased, resulting in more and more sewage discharged from cities. Urban domestic sewage is mainly composed of kitchen washing, toilet flushing, bathing, laundry water, etc. The organic nitrogen and ammonia nitrogen contained in the sewage mainly come from the waste of protein metabolism in human food, such as feces. At present, urban domestic sewage has become the main pollution source of urban water in my country, and the existing sewage treatment facilities are unable to withstand the increasing amount of sewage treatment, resulting in a large amount of domestic sewage being discharged into rivers and lakes without purification, polluting natural wat...
