Example Embodiment

[0024] Example 1

[0025] The water treatment of this embodiment is preferably a filter device, such as figure 1 As shown, it includes two filter columns 1 connected in parallel, a real-time water quality monitor 2 matched with each filter column, and a filter column backwasher 3 matched with each filter column.

[0026] The bottom of the filter column 1 is provided with a base 11, the top side wall of the filter column is provided with a water inlet 18 and an overflow port 19 sequentially from top to bottom, and the bottom side wall of the filter column is provided with a total water outlet 13 and backwashing port 12. The filter column is provided with a filter plate 14, a coarse sand supporting layer 15 and a filter material layer 17 from bottom to top. The side wall of the filter column with the filter material layer is from top to bottom A plurality of sampling tubes 171 are provided, and the bottom end of the side wall of the filter column with the filter material layer is pr...

[0040] Example 2

[0041] The process of filtering material optimization:

[0042] Using the device for water treatment of preferred filter material of Example 1 and the method of water treatment of preferred filter material of Example 1 to optimize 1# and 2# filter media.

[0043] In order to investigate the difference in the filtration performance of the two filter media, compare the filtration effects of the two filter media under the same working conditions. 1# is fine sand with a particle size of 0.7~0.9mm, and 2# is coarse sand with a particle size of 0.9 ~ 1.1mm. The inlet water of the filter column is the effluent from a coagulation sedimentation tank of a water plant. The turbidity of the inlet water is 1.0-2.0 NTU, and the number of particles larger than 2 μm in the inlet water is 4000-8000 / mL. The filtration speed of the two filter columns is the same, ranging from 8 to 12m / h. The total number of particles in and out of the water, particle size distribution and turbidity...

Abstract

The present invention belongs to the technical field of water treatment of environmental protection, and particularly relates to a method for optimization selection of water treatment filter material. The method of the present invention uses a water treatment filter material optimization selection apparatus to select the filter material, including filtering water by a filtration column, real-time monitoring the water quality, and backwashing the filtration column. The water treatment filter material optimization selection apparatus includes two parallel filtration columns, real-time water quality monitors matched with each filtration column, and a backwash device matched with each filtration column. A particle counter and a turbidity meter are used for real-time monitoring of turbidity and particulate removal law of different filter materials before and after filtration. The performance of the filter material is determined according to particles and turbidity of the water unitedly. Therefore the problem of optimization selection of filter material for filters is solved. The method for optimization selection of water treatment filter material is suitable for selection of filter materials in new construction and reconstruction projects of water treatment plants, and is also suitable for filter material selection in the wastewater regeneration field. The method is simple in operation, and reliable in results, and has strong operability.

Description

Technical field [0001] The invention belongs to the technical field of water treatment for environmental protection, and in particular relates to a method for water treatment of a preferred filter material. Background technique [0002] In the filtration process of water treatment, the performance of the filter material directly affects the filtration efficiency of the filter and the quality of the filtered water. At present, the selection of filter media in the domestic water treatment process usually relies on experience. In actual operation, it is easy to happen that the effluent from the filter does not reach the expected target. As it is difficult to replace the filter media, the only way to optimize the adjustment is to adjust other operating parameters. Meet the needs of high-quality effluent. When the filter material of a new water plant is laid or the filter material needs to be replaced in an existing water plant, whether the performance of the selected filter material...
