Abstract:

Titanium pigment industries consume a large amount of fresh water with enormous potential of water-saving. Combined with the investigation of present water system of a titanium pigment plant，direct waste water direct reuse system and regeneration cycling water system were designed by mathematical programming. The results showed that freshwater consumption could be saved by 40.0% respectively in direct waste water direct reuse system and regeneration cycling water system，and waste water direct reuse is a better way for water-saving of titanium pigment industry.

摘要：

钛白粉行业是化工行业中的耗水大户，具有较大的节水潜力。本文在对某钛白粉厂水系统现状进行调研的基础上，采用数学规划法，分别从废水直接回用和再生循环两方面对其水系统进行优化设计，结果表明，改造后的两种水系统均比改造前节约新鲜水用量40.0%，并且废水直接回用更加适合钛白粉行业开展节水工作。
