Embodiment 1

[0019] The structure of this industrial water pretreatment ultrafilter comprises an ultrafilter [1], a modified polysulfone hollow fiber membrane [4] is set in the ultrafilter [1], and a quality control tube [9] is set on the side of the ultrafilter [1] ], a pneumatic valve [5], a manual regulating valve [6] and a rotameter [2] are installed on the quality control pipe [9], and a monitor for filtering water quality is set on the purified water pipe at the top of the ultrafilter [1] Spectrophotometer [3]. The modified polysulfone hollow fiber membrane [4] selects the hollow fiber membrane with a molecular weight cut off of 6000 [4] according to the quality of the raw water [7]. The return flow of the quality control pipe [9] is 2 to 5% of the total amount of water inflow. The spectrophotometer [3] is an ultraviolet light absorption photometer.

[0020] The raw water [7] filtered by the media enters the ultra-filter [1] through the manual control valve [6] and the pneumatic va...

Abstract

The invention relates to a polysulfone hollow fiber film (4) that arranged in the ultra-filter (1) for filtering the industry water, while caught molecular weight of said hollow fiber film is 1000-10000; and the side surface of ultra-filter has a quality control tube (9) mounted with a aerated valve (2); and the purify water tube that higher than the top of ultra-filter (1) is a spectrophotometer (3) to detect the quality of filtered water. The water filtered by said ultra-filter can reach following standards: the turbidity is less than 0.1NTU; the pollution index F1 is less than 1.0; the colloid removing rate is higher than 99%; the suspension removing rate is 100%; and the microbe removing rate is 99.9%.

Description

(1) Technical field [0001] The invention relates to an ultra-filter for pre-treatment of industrial water, more precisely the invention relates to an ultra-filter for pre-treatment of industrial water and a water treatment system thereof. (2) Background technology [0002] As we all know, ultrafiltration is a membrane separation technology widely used in the separation, concentration and purification of macromolecular substances. Ultrafiltration separation operates at normal temperature and low pressure, has no phase change, strong oxidation resistance, simple structure, convenient operation, wide application and strong versatility. Water filtration ultrafilters can be used to remove colloidal particles, bacteria, viruses, heat sources and protein macromolecular organic matter in water. It can be used alone to produce industrial water, and can also be used for reverse osmosis influent water pretreatment and high-purity water terminal finishing treatment. Prior art JP57-197...
