摘要
针对常规处理技术难以治理的DSD酸氧化废水,系统介绍了用DSD酸氧化废水制备水煤浆的处理技术。研究表明,用DSD酸氧化废水可直接制备水煤浆,水煤浆的最佳配制浓度为64.5%,相应的水煤浆粘度为932mPa.s;用浓缩后废水配制水煤浆,得出的水煤浆最高配制质量分数可达64.6%～71.5%,相应水煤浆的粘度为823～898 mPa.s;各种条件制备出的水煤浆性能均稳定,完全能满足水煤浆喷吹燃烧的需求。用DSD酸氧化废水制备水煤浆技术可从根本上解决DSD酸生产过程产生的废水污染。
In view of the difficulty in dealing with DSD acid oxidation wastewater by the traditional methods, the technology of water coal slurry made of DSD acid oxidation wastewater is studied. It is pointed out that the highest density of water coal slurry made of raw DSD acid oxidation wastewater could be up to 64.5% and its viscosity was about 932 mPa.s, the highest density of water coal slurry made of concentrated DSD acid oxidation wastewater could be up to 64.6%-71.5%, and its viscosity was about 823-898mPa.s. The properties of water coal slurry made under different conditions were suitable to be jetted and burnt perfectly. The wastewater pollution from DSD acid making process could be solved by making water coal slurry with DSD acid oxidation wastewater completely.
