求翻译：针对传统污泥好氧消化工艺(CAD)存在的供氧动力费用高,需要添加化学药剂(如石灰)调节pH值从而进一步增加处理费用的问题,在不增加基建费用的条件下,对原有的污泥好氧消化工艺的设施进行改造,改良污泥处理的新工艺,这对于国内中小型污水处理厂污泥处理的节能降耗十分有意义.是什么意思？

Oxygen supply power for the tradition of sludge aerobic digestion process (cad) high cost, need to add chemicals (such as lime) and adjust the ph value so as to further increase the cost of processing conditions without increasing the infrastructure costs, the original sludge aerobic digestion proce

For traditional sludge aerobic digestion process (CAD) exist in high-cost power supply of oxygen, you need to add chemicals, such as lime) to adjust pH value so as to further increase the cost of disposal is not an increase in infrastructure costs, the conditions of the original sludge aerobic diges

Is high in view of the traditional sludge good oxygen digestion craft (CAD) existence for the oxygen power cost, thus needs to increase the chemical agent (like lime) to adjust the pH value further to increase the processing expense the question, in does not increase the capital construction expense

For traditional sludge good oxygen digestive technology (CAD) exists of for oxygen power costs high, needs added chemical pharmaceutical (as lime) Regulation pH value to further increased processing costs of problem, in does not increased infrastructure costs of conditions Xia, on original of sludge
