Embodiment 1

[0013] Embodiment 1: This embodiment provides a method for treating sewage with a new type of carrier biological turntable. The method for treating sewage is: (1) passing the sewage into the primary sedimentation tank through the water inlet, and then using 1L sewage 30g flocculant The proportion of flocculants is added to make most of the suspended solids and inorganic particles in the wastewater settle down; (2) The treated sewage is passed into the nano-aeration device and the sewage is subjected to nano-aeration treatment at a temperature of 100 °C for 24 hours. Prevent free microorganisms from competing with the microorganisms on the filler for organic nutrients; (3) Pass the sewage into the biological turntable integrated device, and 50% of the surface of the turntable is immersed in the sewage. Organic matter and inorganic matter are nutrients, multiply by themselves and form a biofilm on the turntable to absorb and filter pollutants in the sewage; (4) The sewage treated...

Embodiment 2

[0016] Embodiment 2: This embodiment provides a method for treating sewage with a novel carrier biological turntable. The method for treating sewage is as follows: (1) Pass the sewage into the primary sedimentation tank through the water inlet, and then use 1L sewage 30g flocculant The proportion of flocculants is added to make most of the suspended solids and inorganic particles in the wastewater settle down; (2) The treated sewage is passed into the nano-aeration device and the sewage is treated with nano-aeration at a temperature of 125 ° C for 30 hours. Prevent free microorganisms from competing with the microorganisms on the filler for organic nutrients; (3) Pass the sewage into the biological turntable integrated device, and 50% of the surface of the turntable is immersed in the sewage. Organic matter and inorganic matter are nutrients, multiply by themselves and form a biofilm on the turntable to absorb and filter pollutants in the sewage; (4) The sewage treated by the b...

Embodiment 3

[0019] Embodiment 3: This embodiment provides a method for treating sewage with a novel carrier biological turntable. The method for treating sewage is as follows: (1) Pass the sewage into the primary sedimentation tank through the water inlet, and then use 1L sewage 30g flocculant The proportion of flocculant is added to make most of the suspended solids and inorganic particles in the wastewater settle down; (2) The treated sewage is passed into the nano-aeration device and the sewage is subjected to nano-aeration treatment at a temperature of 150 ° C for 36 hours. Prevent free microorganisms from competing with the microorganisms on the filler for organic nutrients; (3) Pass the sewage into the biological turntable integrated device, and 50% of the surface of the turntable is immersed in the sewage. Organic matter and inorganic matter are nutrients, multiply by themselves and form a biofilm on the turntable to absorb and filter pollutants in the sewage; (4) The sewage treated...

Abstract

The invention discloses a novel carrier biological rotating disk based sewage treatment method. The method includes: settling most of suspended solids and inorganic particles in sewage in a primary settling tank, and performing nano aeration treatment in a nano aeration device for 24-36h; feeding the sewage into a biological rotating disk integrated device to perform adsorption and filtration treatment on pollutants in the sewage; feeding ozone into a secondary settling tank with a turbine under strong ultraviolet irradiation, allowing complete contact of the ozone and the sewage under the action of the turbine, and discharging after sterilization treatment. The novel carrier biological rotating disk based sewage treatment method has advantages of simplicity, high treatment efficiency, economy and practicality.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for treating sewage with a novel carrier biological turntable. Background technique [0002] Today, China is in a critical period of economic development and the gradual improvement of people's living standards, and with the increase of urban population and the development of industrial and agricultural production, the sewage generated in the process of social production and life is also increasing and due to the rapid development of industrial and agricultural production , the various chemical elements and microorganisms in the sewage also increased. Although the existing biochemical sewage treatment system can meet the water quality requirements of the discharged water, with the improvement of environmental protection requirements, the existing sewage treatment system still needs to be improved. In order to further enhance its sewage treatment effect and impro...
