Embodiment approach

[0039] According to a preferred embodiment of the present invention, the primary treatment unit includes a water distribution well 1 , a fine grid 2 and a regulating tank 3 arranged in sequence.

[0040] In the present invention, after the sewage is treated in the grit chamber, it enters the water distribution well, so as to reduce the impact of flow changes on the subsequent treatment system.

[0041] Further, a water pump is provided between the distribution well 1 and the fine grid, and between the fine grid and the regulating tank.

[0042] Furthermore, the gap between the bars of the fine grid 2 is 4-8mm, so as to intercept suspended matter and floating matter.

[0043] Among them, the sewage removes larger floating and suspended solids in the fine grid, and then enters the regulating tank to uniform the water quality and water quantity.

[0044] According to a preferred embodiment of the present invention, the primary treatment unit further includes an air flotation dev...

Embodiment 1

[0219] The sewage treatment equipment in the low temperature area described in this embodiment is specifically as follows:

[0220] In the primary treatment unit, the water distribution well, the fine grid, the adjustment tank and the air flotation device are connected in sequence, and the gap between the grids of the fine grid is 6mm.

[0221]In the air flotation device: the ratio of the vertical height of the water baffle to the top of the tank and the vertical height of the water baffle to the bottom of the tank is 13:1; the diameter of the water passing hole and the diameter of the water baffle The ratio is 1:9; the diameter ratio of the circular deflector to the water baffle is 1:6; the vertical height of the fixed bracket is 1 / 4 of the vertical height from the water baffle to the bottom of the tank; the vertical pipe The vertical height from the top to the water barrier is 100mm; the ratio of the vertical height of the steady flow release part to the vertical height of t...

Embodiment 2

[0233] This embodiment is similar to Embodiment 1, the difference is that in the air flotation device: the ratio of the vertical height of the water-repelling baffle from the top of the tank to the vertical height of the water-repelling baffle from the bottom of the tank is 6:1; The diameter ratio of the diameter of the round water hole to the water baffle is 1:6; the diameter ratio of the circular deflector to the water baffle is 1:4; the vertical height of the fixing bracket is the distance from the water baffle to the bottom of the tank 1 / 3 of the vertical height of the vertical pipe; the vertical height of the top of the vertical pipe from the water barrier is 80mm; the ratio of the vertical height of the steady flow release part to the vertical height of the tank is 3:40; The cross-sectional diameter is 1 / 4 of the cross-sectional diameter of the columnar tank; the vertical height of the guide cylinder is 3 / 5 of the vertical height of the columnar tank; there are two rows o...

Abstract

The invention discloses low-temperature area sewage treatment equipment which comprises a primary treatment unit (100) and an advanced treatment unit (200) which are sequentially arranged so as to treat sewage step by step, and a heating unit (300) which is arranged between the primary treatment unit and the advanced treatment unit. According to the equipment, the utilization rate of microbubblesof the air floatation device is increased, the heating pipeline and the heat preservation layer are additionally arranged before deep evolution of sewage, and immobilized microorganism carrier filleris adopted, so that the metabolic capability of sewage treatment microorganisms in a low-temperature region is improved, energy consumption is reduced, and degradation of the sewage is promoted.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to sewage treatment in low-temperature areas, and in particular to sewage treatment equipment and methods in low-temperature areas. Background technique [0002] With the continuous development of industry, the use of water resources has also increased, but there is less than 1% of fresh water on the earth, and only about 0.007% of the water can be directly used by humans. Therefore, water conservation and reuse Water resources are called the focus of attention. In the reuse of water resources, sewage treatment is the top priority. [0003] At present, the methods of sewage treatment include physical method, chemical method and biological treatment method. my country has put forward strict requirements for increasing standards and increasing efficiency for urban sewage. Efficient denitrification and low-cost advanced treatment have become common technical problems faced by sewage t...
