Sludge drying is an important link in the process of sludge pyrolysis and incineration,and the wastewater generated in the process of drying is condensed wastewater,which has the characteristics of high total nitrogen,high ammonia nitrogen,low alkalinity and low carbon-nitrogen ratio.There are few achievements in research on this type of wastewater.The pollutant composition of condensed wastewater is similar to urban sewage,the treatment processes of condensation wastewater under different operating conditions vary,it is recommended to prioritize low-cost activated sludge treatment method.This article takes a low-temperature-drying condensation wastewater project in Sichuan Province as an example,and analyzes in detail the treatment process,sewage unit design,construction investment,and operating costs of the 200 m3/d sewage treatment system which built for the 200 t/d sludge drying project.
