The world's first batch operation process is a British engineer Sim ThomasWardle in 1898 found that in 1914 the practical application of Salford in the UK municipal sewage treatment, and later as the process is cumbersome operation mode operation, the air diffuser is easy to plug and awareness the problem has not been promoted.
From the reliability of the system, civil works, total installed capacity, energy, reduces operating costs and other aspects of land conservation point of view, have obvious advantages [4]. 1.7 Oxidation Ditch Aka oxide oxidation ditches drainage, because the structure was named after closed-shaped ditches.
