With the gradual improvement of urbanization in China,the amount of municipal waste is also increasing daily,and waste incineration power generation has become one of the primary disposal method.The stacking and fermentation process in the pit before waste incineration will produce more leachate,if not treated in time,not only can affect the calorific value of the waste in the furnace,but also easy to cause the secondary pollution problems of soil,atmosphere,water and so on.In order to realize the intelligent and efficient operation of the leachate treatment system of the waste incineration power plant,aiming at the problems of many types of equipment,complex operation and high labor cost in the leachate treatment system,this paper integrates fieldbus technology into the practical application,effectively improving the leachate treatment level of the waste incineration power plant,and provides an effective solution for the leachate disposal in the construction of the intelligent power plant.
