Embodiment 1

[0020] Embodiment 1 takes Changzhou canal source water as an example. Source water is composed of O 3 The water inlet pipe 4 of the dissolution tank enters, O 3 The height of the dissolution pool is 3.2 meters, the length is 3.0 meters, and the width is 2.5 meters. When the pressure is 0.06-0.12MPa, O 3 Oxygenated gas by O 3 The intake pipe 9 leads into, O 3 The dosage is 1.0-2.0Mg / L,, O 3 Contact with the source water for 10-15 minutes for oxidation, and then the source water comes out of the outlet pipe 8 and flows countercurrently into the zeolite filter tank 2. The height of the zeolite filter tank is 4.2 meters, the diameter is 3.0 meters, and the thickness of the filter layer of the zeolite filter tank is 1.0-2.0 meters, the filtration rate is 10-12 meters per hour, and the water flow out from the zeolite filter tank outlet pipe 12 finally enters the activated carbon filter tank 3 downstream. The activated carbon filter tank can adopt a reinforced concrete structure ...

Embodiment 2

[0021] Embodiment 2 takes the source water of Gehu Lake as an example. Source water is composed of O 3 The water inlet pipe 4 of the dissolution tank enters, O 3 The height of the dissolution pool is 3.5 meters and the width is 1.0 meters. When the pressure is 0.08-0.13MPa, O 3 The degassing gas is passed into through the intake pipe 9, O 3 The dosage is 1.5-3.0Mg / L, O 3 Oxidation time in contact with source water is 20-30 minutes, in O 3 Glass filler is added to the filler layer 5 of the dissolution tank to increase the O 3 The solubility of the gas in water, the thickness of the glass filler is 1.0-1.5 meters, from O 3 The water source water coming out of the gas dissolving tank outlet pipe 8 enters the activated carbon filter 3 downstream, the activated carbon filter can adopt a reinforced concrete structure, the height is 4.2 meters, the thickness of the filter layer of the GAC filter is 1.5-2.0 meters, and the filtration speed is 8- 10 m / h. The source water that co...

Abstract

The present invention belongs to the field of environment protection technology, in particular it relates to a method for treating water of microcontaminated water source. Said method includes the following measures: low pressure feeding air, parallel-connecting water flows, ozonizing gas parallel-connection to make addition, utilizing zeolite to make counterflow filtration and implement downstream regeneration, implementing zeolite and active carbon two-stage biochemical synergistic effect, adding glass filler as filling medium, raising O3 and O2 gas solubility and removing tail gas absorption breaking device. Said treatment method is simple and cost is low.

Description

technical field [0001] The invention belongs to the field of environmental protection technology treatment, and in particular relates to a method for treating slightly polluted water source water. Background technique [0002] The development of industrialization and urbanization continues to advance, and the water supply and drainage increase simultaneously, which inevitably pollutes the water environment and deteriorates the quality of tap water. It often causes sensory disturbance, abnormal taste, and gastrointestinal discomfort, so that teratogenicity and carcinogenicity are potential threats to human health. According to the characteristics of slightly polluted source water, biological oxidation, chemical oxidation, membrane separation technology, activated carbon adsorption and other treatment methods are widely used at home and abroad. [0003] Biooxidative degradation of pollutants in water, including aeration, oxygenation, oxidation, biodegradation, nitrification, ...
