specific Embodiment approach 1
[0028] Specific implementation mode one: a kind of post-ultrafiltration activated carbon filter of the present embodiment removes the strengthening method of ammonia nitrogen and organic matter according to the following steps:
[0029] 1. Set up a pre-treatment unit in front of the activated carbon filter: use the coagulation and sedimentation process to treat the source water, and remove the particulate matter before effluent;
[0030] 2. Change the activated carbon filter to an upward-flowing activated carbon filter: When the concentration of ammonia nitrogen in the effluent in step 1 is less than 1.5mg / L and the potassium permanganate index is less than 3mg / L, first change the activated carbon filter to an upward-flowing activated carbon filter , and then the effluent treated in step 1 enters the upward-flowing activated carbon filter for treatment for 10 minutes to 30 minutes, and the effluent is effluent after the treatment is completed. Wherein, when the step 1 effluent...
specific Embodiment approach 2
[0032] Specific embodiment two: the difference between this embodiment and specific embodiment one is that in step two, the effluent treated in step one enters the upstream activated carbon filter for processing for 20 minutes, and the water is discharged after the treatment is completed; wherein each of the upstream activated carbon filters is controlled Parameters: The filtration rate of the upward-flowing activated carbon filter is 10m / h~12m / h; the thickness of the activated carbon layer of the upward-flowing activated carbon filter is 2.5m; the backwashing intensity of the upward-flowing activated carbon filter is 15L / s m 2 ; In step 3, the effluent treated in step 2 enters the ultrafiltration unit for filtration for 60 minutes, and then backwashes the ultrafiltration membrane for 1 minute; the ultrafiltration unit is an internal pressure ultrafiltration membrane module or submerged ultrafiltration Membrane module; the transmembrane pressure of the internal pressure ultrafi...
specific Embodiment approach 3
[0033] Specific implementation mode three: a kind of post-ultrafiltration activated carbon filter tank of the present embodiment removes ammonia nitrogen and the strengthening method of organic matter according to the following steps:
[0034] 1. Set up a pre-treatment unit in front of the activated carbon filter: use the coagulation and sedimentation process to treat the source water, and remove the particulate matter before effluent;
[0035] 2. Set up an ozone unit before the activated carbon filter: when the concentration of ammonia nitrogen in the effluent of step 1 is less than 1.5mg / L and the potassium permanganate index is greater than 3mg / L, add 1mg / L to 2mg / L to the effluent treated in step 1 The amount of L is passed through the ozone treatment for 10 minutes to 30 minutes and then the water is discharged;
[0036] 3. Change the activated carbon filter to an upward activated carbon filter: first change the activated carbon filter to an upward activated carbon filter...
