Abstract

A comparative techno-economic estimate of the cost of HOAC producing from technical aluminum hydroxide and hydroxide sludge showed that the cost of HOAC would be decreased by 11% by using a hydroxide precipitate. The cost of operation on the hydroxide precipitate will decrease by 17.3% provided the storage vessel is converted into a reactor to neutralize the acid solution of HOAC. This is possible due to doubling the production of HOAC, moreover production volumes will amount to 7178.2 thousand rubles. The calculated payback period for capital investments for retrofitting is 1 month. Keywords: coagulant, aluminum hydroxychloride, hydroxide precipitate, aluminum- containing waste

技术级氢氧化铝与氢氧化铝污泥混凝剂生产成本的技术经济对比评价

通过对氢氧化铝和氢氧化铝污泥生产氢氧化铝的成本进行技术经济比较，发现使用氢氧化铝沉淀物可使生产氢氧化铝的成本降低11%。如果将储存容器改造成反应器来中和HOAC的酸性溶液，则氢氧化物沉淀的运行成本将降低17.3%。这是可能的，因为HOAC的产量增加了一倍，而且产量将达到717.82万卢布。改造资本投资的计算回收期为1个月。关键词:混凝剂，羟氯化铝，氢氧化物沉淀，含铝废物
