Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of precipitation equipment, and particularly relates to a silicon-removing precipitation solidification device. BACKGROUND

[0002] Slow precipitation can lead to prolonged sewage treatment period, making it difficult to meet the water quality standards, and further affecting the compliance of subsequent treatment processes and final discharge. The root cause of such slow precipitation is usually related to the design of the device, the characteristics of the sewage and the dosage of the precipitant. In particular, for sewage containing fine silicon particles, the traditional gravity sedimentation method is difficult to effectively separate, and these particles stay in water for a long time beyond the expected time, resulting in poor precipitation effect.

[0003] To address this problem, conventional methods include increasing the precipitation time, increasing the dosage of the precipitant or using mechanical stirring, etc. to enhance the settling speed of the particles. However, these methods also have their limitations. Although prolonging the precipitation time can improve the precipitation effect, it will increase the occupied area of the treatment facility, thereby reducing the treatment capacity of the system, and therefore we hope to design a new type of precipitation device to solve this problem.
