Zusammenfassung:	The invention provides a system and a method for co-processing waste liquid and household garbage incineration fly ash in a cement kiln. The method comprises the following steps: modifying the household garbage incineration fly ash by using a small amount of quick lime, mixing with waste hydrochloric acid, waste emulsion and the like, reacting, and separating to obtain high-added-value materials such as organic aggregate, fine powder, high-calorific-value waste oil, superfine calcium carbonate, ammonium chloride crystals, carnallite and the like. Meanwhile, the process is coupled with a cement clinker production line, and partial material absorption is realized by utilizing the characteristics that a flue gas system of the cement production line contains waste heat, a sintering system needs to supplement heat and a raw material batching station system needs to supplement water. The system and the method have the characteristics that the industrial solid waste is treated in a manner of treating waste with wast
