Embodiment 1
[0058] The specific parameters of the processing device used in this embodiment are set as follows:
[0059] Water to be treated: The leachate from a landfill is treated by a two-stage upflow anaerobic sludge bed (UASB) reactor. To more than 95% of the total nitrogen concentration, the treatment scale is about 800m 3 / d.
[0060] Such as figure 1 As shown, the integrated treatment device is composed of two reactor modules (the first reactor module and the second reactor module), one settling module and one gas-liquid separation module, wherein the first reactor module includes the second reactor module One reactor 11, the second reactor module includes the second reactor 21, the settling module includes the third reactor 31, the first reactor 11, the second reactor 21 and the third reactor 31 are sequentially stacked and connected from bottom to top A cylinder with a section diameter of 6m and a height of about 18m is formed.
[0061] First Reactor Module:
[0062] The cr...
Embodiment 2
[0090] Water to be treated: A municipal sewage is pretreated by a 2-stage anaerobic baffle (ABR) reactor. The concentration of BCOD is 30-60mg / L, the concentration of ammonia nitrogen is 40-70mg / L, and ammonia nitrogen accounts for 95% of the total nitrogen concentration. % above, the processing scale is about 6400m 3 / d.
[0091] The structure of the integrated sewage treatment plant is basically the same as in Example 1, the differences are as follows:
[0092] The first reactor 11, the second reactor 21, and the third reactor 31 are sequentially connected to form a main body with a cross-sectional diameter of 8 m and a height of about 19 m.
[0093] The first reactor 11 and the second reactor 21 have the same size, with a cross-sectional diameter of 8m, a height of 8m, and a hydraulic retention time of about 2.5h (calculated on the basis of 60% influent flow rate).
[0094] There are altogether 18 water distribution pipes (16), arranged in three layers, with a pipe diamet...

Abstract
The invention relates to an integrated sewage treatment method. The integrated sewage treatment method adopts an integrated sewage treatment device to treat the sewage to be treated. The integrated sewage treatment device includes a first reactor module, a second reactor module, a settling module and an air Liquid separation module, the first reactor module includes the first reactor, anoxic reaction zone, aerobic reaction zone, the first gas-collecting pressurized layer, the first water inlet pipe, and aeration device; the second reactor module includes the second Reactor, second water inlet pipe, anaerobic reaction zone, second gas-collecting pressurized layer; settling module includes third reactor, water outlet pipe; gas-liquid separation module includes gas-liquid separator, exhaust pipe, first upflow tube, second riser tube, return tube. The present invention can stably operate the denitrification-nitrosation-anammox combination process, thereby forming a relatively stable functional flora with large biomass, which is beneficial to improve the denitrification performance, reduce the volume of the device, and has strong water quality adaptability and impact resistance.
Description
technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an integrated sewage treatment method. Background technique [0002] At present, how to realize "energy self-sufficiency and material circulation" has become an important development direction in the field of sewage treatment. Among the many solutions, the new A-B process based on COD capture and autotrophic biological denitrification is considered to be a very practical technical route. Among them, section A mainly realizes the enrichment (recovery) or conversion (methanization) of organic matter in sewage through physical and chemical methods or anaerobic biological treatment, while section B uses anaerobic ammonium oxidation as the core to remove organic matter. Nitrogen technology effectively removes nitrogen pollutants in water under the conditions of low C / N ratio, low aeration energy consumption and low sludge production, creating conditions f...
