Coking and coal chemical waste water treatment

Typical Project--Liaoning Ansteel Co., Ltd.

 

The three phase wastewater treatment project of Ansteel is a combined designed project of the Chinese Academy of Sciences and the Design Institute of the Chinese Academy of Sciences in 2009. The project used treatment process of A2/O2+high efficiency coagulation + multi media filtration + ozonation + biological aerated filtration tank. Ozone generator is required for one set with capacity of 12.5kg/h for 400m3/h treated capacity, The COD of effluent is less than 100mg/L, ammonia nitrogen values is less than 10mg/l and total cyanide is less than 0.2mg/L.

After six years of operation, the equipment is in good condition and all technical indexes are stable.

Ozone function

Coking and coal chemical wastewater is mainly coming from coal gasification, liquefaction and coking process. The main characteristics of waste water are complex composition, containing a large number of solid suspended particles, volatile phenol, condensed aromatic rings, pyrrole, furfuran, iminazole, naphthalene, cyanide, oil, ammonia nitrogen, sulfide and heterocyclic compound contains nitrogen, oxygen and sulfur. COD value and chroma are very high. Genera speaking, ozone is used combining with SDN (enhanced nitrification / denitrification) and HSB (high - decomposing bacteria group) process to decompose organic compounds and toxic and harmful substances by ozone oxidation ability, so that it can remove the chroma and odor in waste water to make effluent meeting discharge standards.
