Problems solved by technology

Biofilters have the advantages of rich microbial species, large biomass, long food chain, and less residual sludge production, and are suitable for low-concentration sewage treatment. However, the mechanism of pollutant removal in biofilters is not very clear so far. To develop its treatment potential; at the same time, how to further strengthen its biological effect has not been systematically and deeply studied

Embodiment 1

[0033] The secondary effluent (short-cut nitrification-denitrification effluent) after treatment in a family area of ​​a university was used as the experimental object. The effective volume of the anammox biofilter reactor is 16L, with FILTRALITE HR3-6mm (Norway, expanded clay) (preferred) as the filter material, the height of the filter material layer is 1.2m, the height of the supporting layer is 0.2m, continuous water intake, The influent filtration rate is maintained at 0.5m / h, and the influent ammonia nitrogen: nitrite nitrogen mass concentration ratio is maintained at 1:1.32. Concentration is 18mg / L, The concentration is 24mg / L; the reaction temperature is controlled within the range of 30-33°C by a temperature control device.

[0034] 1) Start-up phase: Fill the reactor water bath jacket with water, turn on the temperature control device, and control the temperature at 30-33°C; use a peristaltic pump to pump the mature anammox sludge to be inoculated from the reactor...

Abstract

The invention discloses a method and a device for rapidly realizing anaerobic ammonia oxidation of a bacteria filter, belongs to the technical field of sewage treatment. The device comprises a cylindrical reaction device, a water inlet tank, an aeration disc, a water collecting trough, a backflush water inlet pipe, a backflush water outlet pipe, a backflush water pump, a backflush air inlet pipe and a pressure gauge, wherein the temperature of the whole reaction process is controlled to be 30 to 33 DEG C; the ratio of ammonia nitrogen to nitrite nitrogen is 1:1.32; the filtration rate of a control system is 1.5 to 2.0m / h; the backflush cycle and strength of the bacteria filter are controlled through feature points based on pressure value variation. The method and the device are beneficial to economically and effectively controlling water nitrogen pollution, and improve the sewage deep denitrification efficiency and the water quality of reuse water.

Description

technical field [0001] The present invention relates to a rapid implementation method of nitrogenous wastewater biological treatment process, which can save about 62.5% of oxygen supply and 100% of additional carbon source compared with traditional nitrification-denitrification denitrification process, and the sludge output can be reduced by 70% ~80%. It is suitable for the advanced treatment of sludge digestion liquid, landfill leachate and secondary water of sewage treatment plants, which is conducive to economically and effectively controlling nitrogen pollution in water bodies, improving the efficiency of deep denitrification of sewage and the quality of reused water, and reducing the cost of reused water treatment. It belongs to the technical field of sewage treatment. Background technique [0002] With the rapid development of social economy, environmental problems are increasingly concerned by human beings. Among them, the eutrophication phenomenon of water bodies (r...
