A/O combined micro electric field-Fe/C enhanced phosphorus removal device and application of phosphorus removal device

Abstract

The invention discloses an A / O combined micro electric field-Fe / C process enhanced phosphorus removal device and application of the phosphorus removal device. The device comprises an anaerobic acidification tank, an intermittent aeration tank and a micro electric field-Fe / C reaction zone arranged in sequence, and further comprises an aeration system, wherein the intermittent aeration tank and themicro electric field-Fe / C reaction zone are respectively connected with the aeration system pipeline, the micro electric field-Fe / C reaction zone comprises a main reaction zone, a disinfection tank and a sludge concentration tank arranged in sequence, and the intermittent aeration tank is connected to an upper part of the sludge concentration tank through a first return pipeline; the device is stable in operation and high in efficiency, and the device can effectively remove phosphorus, nitrogen and organic matters in the sewage. The treated water quality can reach the first-class A standard ofsurface water.

Description

technical field [0001] The invention relates to an environmental protection device and its application field, in particular to an A / O combined micro-electric field-Fe / C enhanced dephosphorization device and its application. Background technique [0002] With the rapid development of my country's industry and the acceleration of urbanization, the demand for water resources has increased significantly, which has exceeded the exploitation potential of available water resources, forming the so-called water shortage. On the other hand, water pollution makes the originally usable water resources unusable, resulting in water quality-related water shortages, which further exacerbates the degree of water resource shortages. Therefore, to solve the problem of shortage of water resources, it is necessary not only to increase the source of water and reduce expenditure, but also to control water pollution. [0003] Nitrogen and phosphorus pollution in water pollution have attracted more...
