A. only for organic sludge B. Only used for high concentration of organic waste water C. not only for organic sludge, high concentration of organic waste water, but also to efficiently handle low-concentration sewage such as urban sewage D. Can only be used for simple sewage treatment 5 points out: The result of the reactive sludge reaction is (). The inorganic pollutants in the sewage are degraded, the sewage is purified, and the active sludge itself is proliferated The organic pollutants in the sewage are degraded, the sewage is purified and the active sludge itself is proliferating C. the organic pollutants in the sewage are degraded, the sewage is purified, and the microbes are consumed and dying The inorganic pollutants in the sewage are degraded, the sewage is purified, and the active sludge itself is proliferated 5 points out: The discharge of nitrogen in urban sewage is mainly used ().
