The invention relates to a
coal chemical industry sewage disposal method, and particularly relates to a high-efficient conny pressure gasification high-concentration
sewage disposal method. Specific to the difficulty of treating the conny pressure gasification high-concentration
sewage of a
coal chemical industry, the invention aims to overcome the shortcomings existed in a traditional technique and provides a conny pressure gasification high-concentration sewage disposal method for triggering
polymerization-promoting oil removal and
turbidity removal, intensified oxidization,
shunting type two-grade
oxygen deficit / aerobiotic
system, high-efficient low-consumption catalyst
ozone oxidizing treatment
coupling, and compact type
biochemistry technical
coupling with multiple novel high-efficient units. The method fully combines inherent characteristics of every unit, realizes the high-efficient removal of phenolic substance, oily substance, and heterocyclic
ring type substance in waste water, fully displays the handling ability of the biochemical
system, and stabilizes and promotes the
effluent quality of the biochemical
system. The whole method is featured by strong
impact resistance, simple flow, low handling cost, and others; indexes of
effluent COD,
ammonia nitrogen,
total nitrogen and specific
pollutant are significantly better than the like waste water disposal level of the industry, and the method also has good popularization and application prospects.
