A solar heating type mainstream domestic sewage anaerobic ammonium oxidation greenhouse reaction tank

Abstract

The invention relates to a solar energy heat-supply type main stream domestic sewage anaerobic ammonium oxidation greenhouse reaction tank, which comprises a reactor body, wherein the reactor body sequentially comprises a reflux water distribution unit, a mud discharge unit, an autotrophy denitrogenation unit, a three-phase separation unit and a water outlet gas discharge unit from bottom to top, the reflux water distribution unit is provided with a water inlet pipe, a nitrogen reflux pipe and an effluent reflux pipe, the mud discharge port of the mud discharge unit is arranged on the side surface of the bottom end of the reactor body, the three-phase separation region is provided with an upper gas collection cover, a lower gas collection cover, a diversion pipe and a water collection pool, the water outlet unit comprises a water outlet groove and a water discharge port, the outer portion of the reactor body is provided with a greenhouse cover, the upper portion of the greenhouse cover is provided with an exhaust fan, an external temperature probe is arranged between the greenhouse cover and the upper cabinet, and an internal temperature probe is arranged in the upper cabinet. The solar energy heat-supply type main stream domestic sewage anaerobic ammonium oxidation greenhouse reaction tank has the following beneficial effects that: with the greenhouse cover, the adverse impact of the seasonal and nycterohemeral temperature difference on the denitrogenation performance of the anaerobic ammonium oxidation reactor can be released; and the water outlet and nitrogen reflux system has effects of strong impact load resistance, sufficient upflow velocity and shear force providing, and sludge granulation promoting.

Description

technical field [0001] The invention relates to a solar heating type mainstream domestic sewage anaerobic ammonium oxidation greenhouse reaction tank. Background technique [0002] With the continuous advancement of the pace of urbanization in my country, the recycling and energy recovery of urban domestic sewage has increasingly become the focus of society. At present, energy, cost-effectiveness and sustainable development have gradually evolved into benchmarks for the urban domestic sewage treatment industry, which is important for improving urban residents. It is of great significance to improve living standards and build an ecologically civilized city with energy saving and low consumption. However, the traditional urban sewage treatment process consumes a lot of energy and has low energy utilization rate. High-efficiency and low-consumption treatment technology has always been a difficulty and hot spot in the field of domestic sewage treatment. [0003] Autotrophic anae...
