Integrated biological magnetic water treatment equipment

Abstract

The invention discloses an integrated biological magnetic water treating device. An internal zone is mainly formed by five zones, namely, an anoxic zone, a nitrifying liquid recirculation zone, a coagu-flocculation reaction zone and a settling zone, wherein an aerobic zone is arranged as an external annular zone; the internal zone and the external zone form the shape of Chinese character 'Hui'; the anoxic zone and the nitrifying liquid recirculation zone are adjacently arranged; a reflux pump is arranged on a middle separating plate to communicate the anoxic zone with the nitrifying liquid recirculation zone; the coagu-flocculation reaction zone and the settling zone are adjacently arranged and are communicated with each other through a third water-passing hole; a water inlet pipe is arranged on one side of the anoxic zone while the other side is communicated with the aerobic zone through a first water-passing hole; the aerobic zone is communicated with the nitrifying liquid recirculation zone through a fourth water-passing hole; the aerobic zone is communicated with the coagu-flocculation reaction zone through a second water-passing hole; a water outlet pipe is arranged in the settling zone. According to the invention, the traditional A / O technique and a settling pond are integrally built; the overall floor space of the whole sewage treatment technique is greatly saved; the integrated biological magnetic water treating device has the advantages of reasonable layout, equivalent processing load, uniform flow speed and stable and reliable operation.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an integrated biological magnetic water treatment equipment. Background technique [0002] The water treatment process for domestic sewage or similar industrial organic sewage often adopts a relatively mature A / O-precipitation method, mainly using activated sludge method to remove organic pollutants and denitrification. Such as figure 1 As shown, the traditional A / O pool is usually composed of the following three parts in series: anoxic zone 1, aerobic zone 2 and precipitation zone 3. The main function of the anoxic stage is denitrification and denitrification, and denitrifying bacteria use nitric acid The root ion is used as the final electron acceptor to oxidize the organic matter in the sewage for energy production and proliferation. At the same time, the nitrate is dissimilated and reduced to produce N2 and escape from the water, so as to achieve the purpose...

AI Technical Summary

Problems solved by technology

[0003] This traditional A / O process requires the separate construction of each reaction tank monomer, which occupies a large area and requires additional equipment such as external pipes; the subsequent sedimentation area mainly relies on layered sedimentation or compressed sedimentation to achieve clarification and sludge concentration. Function, its sludge settling speed, water discharge load, surface load and other parameters are small, in order to achieve a good enough water discharge effect, its treatment area will also increase accordingly
