Innovation and practice of the advanced treatment and reuse technologies for coking wastewater

In order to solve the problems,such as fresh water shortage and no place to discharge wastewater in cok?ing enterprises,the advanced treatment and reuse technologies for coking wastewater have been developed. Com?bined with three typical cases,the technical innovations and practical experiences on engineering application are introduced. According to wastewater characteristics ,current processes and reusing ways in different enterprises , technologically and economically reasonable combined processes have been used for meeting the individual needs of users,so as to make the coking wastewater,which was considered as an important pollution source in the past, achieve'Turning waste into wealth'. The technologies have made the wastewater harzard?free,waste reduced and resource utilized,and obtained good environmental and economic benefits.
