Embodiment 1

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] Depend on figure 1 As shown, the integrated high-efficiency bioreactor includes anoxic zone 1, anaerobic zone 2, hypoxic zone 3, hypoxic packing zone 4, sedimentation zone 5, filter cloth filtration zone 6 and disinfection zone 7;

[0049] An anoxic zone 1 side wall is provided with a water inlet pipe 8, a first partition wall is set between the anoxic zone 1 and anaerobic zone 2, and a first diversion wall is set at a position away from the two ends of the first partition wall, and in the anaerobic zone 2 A variable frequency submersible thruster 11a is set in the water flow direction of the inner and anoxic zone 1;

[0050] The anaerobic zone 2 communicates with the hypoxic zone 3 through the water hole 22 arranged on the side wall. In the hypoxic zone 3, a second partition wall is arranged parallel to the first partition wall, and at a positi...

Abstract

The invention relates to an integrated efficient biological reactor and reaction process thereof. The integrated efficient biological reactor comprises an anoxic zone, an anaerobic zone, a hypoxic zone, a hypoxic filling zone, a precipitation zone, a filter cloth filtering zone and a sterilizing zone. The reactor adopts the integrated structure, is compact in overall design and occupies a small area. With adoption of the reaction process, the sewage treatment is low in energy consumption the efficiency is high, partial nitrification, synchronous nitrification and denitrification and denitrifying phosphorus removal are realized, and the treatment efficiency of nitrogen and phosphorus removal is high.

Description

technical field [0001] The invention belongs to the field of sewage treatment and relates to a sewage treatment device, in particular to an integrated high-efficiency bioreactor and a process thereof. technical background [0002] Anaerobic-anoxic-aerobic process (A 2 O process) is widely used in the existing urban sewage treatment plants in my country due to its advantages of simple structure, short total hydraulic retention time, small control complexity, and not easy to produce sludge bulking. but A 2 The O process has some problems such as substrate competition, sludge age contradiction, and difficulty in improving the total nitrogen removal rate. Technologies such as short-cut nitrification and denitrification, simultaneous nitrification and denitrification, and denitrification for phosphorus removal can effectively improve A 2 O process efficiency. [0003] It is generally believed that nitrification is completed in two stages, that is, ammonia nitrogen is first ox...
