Coking residuary water contains phenol and cyanogens, which contaminate water source badly. Therefore, the coking residuary water has to be dealt with and discharged.

The obtained achievement in building material industry is studied, including sintering cement with substituting coal by cokeite and smelting rockwool with substituting coke by cokeite and so on.
