System for desiliconizing, dealkalizing and softening industrial wastewater

The utility model provides a system for desiliconizing, dealkalizing and softening industrial wastewater, and relates to the technical field of water treatment. The utility model provides a system for removing silicon and dealkalizing and softening industrial wastewater. The system comprises a sodium metaaluminate dosing reaction concentration device, a tubular microfiltration membrane device, a tubular microfiltration membrane water production tank, an H ion resin exchange bed, a Na ion resin exchange bed and a carbon dioxide removal device. After the wastewater is treated by the system, the alkalinity, hardness and silicon dioxide can be simultaneously removed, the silicon dioxide can be reduced to be less than 10mg/L, the hardness is almost not detected, the alkalinity can be reduced to be less than 20mg/L, and effluent can directly enter a reverse osmosis and evaporative crystallization unit. 本实用新型提供了一种用于工业废水除硅及脱碱软化的系统，涉及水处理技术领域。本实用新型提供的用于工业废水除硅及脱碱软化的系统，包括：偏铝酸钠加药反应浓缩装置、管式微滤膜装置、管式微滤膜产水箱、H离子树脂交换床、Na离子树脂交换床和
