A2/O (Anaerobic/Anoxic/Oxic)Â sewage treatment system, is a kind of biological processing technology, high adaptability for different sewage quality, good anti-load performance, stable output quality, no expanded sludge output and low operation cost.
The A2 / OÂ process is divided into anaerobic, anoxic and oxic segments. The anaerobic and oxic segments are equipped with biological fillers for microbial metabolic activities, along with reactions of hydrolysis and acidification of COD/BOD. Blower and aeration system are installed in the oxic segment, the decomposed organic substance is absorbed by means of aerobic bacteria's metabolism, to achieve the purpose of water purification.
The material and equipment involved in this system are chemical packings and support, chemical additive, air blowers, aerators, overflow weirs, level controller, steady flow tube, agitators(optional),pumps, valves, pipes, connection fittings, filter press, etc;
The flow-chart of A2/O system(If get air flotation system included ahead of A2/O):
Civil works involved include anaerobic pool, anoxic pool, first biological pool, secondary biological pool, secondary sediment pool, sludge basin, disinfection pool and blower room,etc. Equipment involved are fillers&support, blowers, aeration system, sludge press, pumps, pipeline, chemicals and so on.
Sometimes simpler design is also suitable, eg. A/O(Anoxic / Oxic)Â only, in accordance with the characteristics of sewage quality and design requirements.

Metal Stamping Fabrication Service
Metal stamping uses punches and molds to deform or break stainless steel, iron, and other plates and heterogeneous materials to achieve a process with a certain shape and size.
The stamping process can be roughly divided into two categories: the separation process and forming process (also divided into bending, deep drawing, and forming). The separation process is to separate the stamping parts and blanks along a certain contour line during the stamping process, and the quality of the separation section of the stamping parts must also meet certain requirements; the forming process is to make the stamping blanks undergo plastic deformation without damage. And transform it into the required finished shape, and at the same time, it should meet the requirements of dimensional tolerance and other aspects.
According to the temperature during stamping, there are two ways of cold stamping and hot stamping. This depends on the strength, plasticity, thickness, degree of deformation, and equipment capabilities of the material while considering the original heat treatment state and end-use conditions of the material.
