Treatment technology of water treatment device for treating raw water with higher turbidity variation

Abstract

The invention discloses a water treatment device for treating raw water with higher turbidity variation and a water treatment technology of the water treatment device. Due to the characteristic of the wider turbidity variation range of the raw water, pretreatment, conventional treatment, advanced treatment and recycled water treatment processes are optimized and combined, the operation mode can be adjusted under the condition of different turbidities of the raw mater, the treatment procedure is optimized on the premise that the effluent quality is guaranteed, the production water consumption of a water factory is reduced, reusable production wastewater is recycled, and the utilization rate of the raw water is effectively increased. The combination technology has the advantages that the land can be saved, the procedure is optimized, the production water consumption is reduced and the automatic management level is improved, and has a remarkable advantage in the aspect of guarantee of the effluent quality.

Description

[0001] The present invention is a divisional application with the application number 2012100248864 and the title of the invention "a water treatment device for treating raw water with large turbidity fluctuations and its water treatment method". The filing date of the original application is February 6, 2012. technical field [0002] The present invention is a water treatment combination process involved in water supply engineering, specifically, it is applied to a water treatment device and a water treatment process for treating raw water with a large turbidity variation. Optimized combination of pretreatment, conventional treatment, advanced treatment and reuse water treatment process. Background technique [0003] In northern China, there are some surface water sources with a large range of turbidity variation, such as the Baotou section of the Yellow River, where the turbidity variation range is between 32 and 25,000 NTU, which is extremely large. At present, the commonl...
