Problems solved by technology
Because the carbon-nitrogen ratio of urban sewage is generally low (COD / N≤4~6), if the carbon source is not added enough, nitrates will accumulate in the effluent, causing the total nitrogen in the effluent to rise; Carbon will rise, and the effluent is still difficult to meet the standard

Embodiment Construction
[0040] The present invention will be further described below in conjunction with accompanying drawing.
[0041] The whole device of the present invention is an upflow fixed bed continuous flow reactor, the top of which is provided with a water outlet g and a pH probe extension inlet h. The shell of the upflow fixed bed continuous flow reactor is a cylindrical double-layer shell, and the outer layer is an insulating layer 12. The upper and lower ends of the insulating layer 12 are respectively provided with circulating water bath ports I and II. In this implementation, the lower end of the circulating water bath Port I is the water inlet, and port II of the upper circulating water bath is the water outlet.
[0042] The inner layer of the upflow fixed bed continuous flow reactor is the reaction layer, and the reaction layer is divided into two reaction chambers, the upper layer and the lower layer.
[0043]The inner layer of the upflow fixed bed continuous flow reactor is provi...

The invention discloses an integrated denitrification sewage treatment device. An outer layer of an up-flow fixed-bed continuous flow reactor is a heat insulation layer, and an inner layer comprises an upper-layer reaction chamber and a lower-layer reaction chamber; a water inlet and a water outlet of a circulating water bath are arranged at the upper end and the lower end of the heat insulation layer respectively; an exhaust port, the water outlet and a pH probe inlet are arranged at the top of the fixed-bed continuous flow reactor; multiple sampling ports at different heights are formed in the side wall of the reactor and controlled by valves; the upper-layer reaction chamber is filled with non-woven fabric filler with facultative bacteria attached, an aeration device capable of realizing upward aeration is arranged below the non-woven fabric filler, and a three-phase separator is arranged below the aeration device; a round baffle is arranged below the three-phase separator; the lower-layer reaction chamber is located below the round baffle and filled with biofringe filler; the water inlet is arranged at the bottom of the lower-layer reaction chamber, and a water distributor for evenly distributing water in the reactor is arranged above the water inlet. The invention further discloses a sewage treatment method using the device.
Description
technical field [0001] The invention relates to an integrated sewage treatment device for nitrogen removal. [0002] The invention also relates to a method for integrating denitrification-partial nitrosation-anammox sewage treatment by using the above-mentioned device. Background technique [0003] Sewage denitrification treatment is one of the important means to control the eutrophication of receiving water body, and biological denitrification is the most commonly used method in sewage denitrification treatment. The traditional nitrification-denitrification denitrification process, A / O process, etc. usually use the means of adding carbon sources to enhance the denitrification effect. This method also has the risk of adding too much carbon source. Because the carbon-nitrogen ratio of urban sewage is generally low (COD / N≤4~6), if the carbon source is not added enough, nitrates will accumulate in the effluent, causing the total nitrogen in the effluent to rise; Carbon will r...
