Method and device for treating titanium dioxide acid wastewater and by-producing high-quality titanium gypsum
The invention discloses a device and a method for treating titanium dioxide acid wastewater by a membrane method and by-producing high-quality titanium gypsum. The device comprises an acid wastewater regulating tank, an organic membrane purification device, a neutralizer slurry preparation tank, a gypsum crystallization dehydration device, a neutral water storage tank and a neutral water recycling membrane integration device which are communicated in sequence. The method and the device solve the problem of incapability of resource comprehensive utilization caused by low grade, poor chromaticity, small particle size and high water content of titanium gypsum produced by a traditional neutralization process of acid wastewater in the titanium dioxide industry, and the whole set of technology has the advantages of low investment, simple equipment, low energy consumption, stable product quality, good social and economic benefits and facilitation of popularization.
本发明公开了一种膜法处理钛白酸性废水副产高品质钛石膏的装置和方法，该装置包括依次连通的酸性废水调节池、有机膜净化装置、中和剂配浆池、石膏结晶脱水装置、中性水蓄水池、中性水回用膜集成装置。本发明解决了钛白行业酸性废水传统的中和工艺产生的钛石膏品位低、色度差、粒径小和含水率高导致无法资源化综合利用的问题，整套技术投资低，设备简单，能耗低，产品质量稳定，社会效益和经济效益好，利于推广。
