氧化沟设计１污水及回流污泥流入和氧化为混合液流出位置①污水及回流污泥流入位置应尽可能和混合液流出位置分开。②硝化反应的碳源，污水流入位置应设置在厌氧部的始端附近。回流污泥流入位置，设置在污水流入位里附近。因为氧化沟的泥龄（邪Ｔ）长，所以增殖速度慢的硝... Oxidation Ditch Design 1 Wastewater and Returned Sludge Inflow and Oxidation to Mixture Outflow Location 1 Wastewater and return sludge inflow locations should be separated from the liquid mixture outflow location as much as possible. The carbon source for the nitration reaction should be located near the beginning of the anaerobic section. The return sludge flows into the location and is located near the sewage inflow location. Because the oxidation ditch has a long sludge age (evil T), the slower growth rate of nitrate...
