specific Embodiment approach 1

[0021] Specific embodiment one: the activated carbon and ultrafiltration membrane combination device that removes trace pharmaceuticals in tap water, it comprises water inlet pipe 1, the first granular activated carbon column outlet 2, granular activated carbon column 3, ultrafiltration membrane 4, pressure sensor 5, ultrafiltration membrane Filtration membrane suction pump 6, ultrafiltration membrane pool 7, ultrafiltration membrane pool outlet 8, clean water tank 9, backwash water pump 10, first check valve 11, flow valve 12, clean water tank inlet 13, second Water inlet 14 for the second granular activated carbon column, water outlet 15 for the second granular activated carbon column, water inlet 16 for the ultrafiltration membrane pool, valve 17, water inlet 18 for the first granular activated carbon column, first drainage pipe 19, water outlet 20 for the clean water tank, a second drain pipe 21 and a second check valve 22;

[0022] The first granular activated carbon colu...

specific Embodiment approach 2

[0032] Specific embodiment two: this embodiment is to use the activated carbon and the ultrafiltration membrane combination device of removing trace pharmaceuticals in tap water to remove the method for trace pharmaceuticals in tap water, specifically according to the following steps:

[0033] 1. Fill the modified granular activated carbon into the granular activated carbon column 3: fill the modified granular activated carbon into the granular activated carbon column 3;

[0034] The volume ratio of the modified granular activated carbon described in step 1 and the granular activated carbon column 3 is (0.65~0.8):1;

[0035] 2. Treatment of tap water containing trace amounts of pharmaceuticals: close the first granular activated carbon column drain 2, the ultrafiltration membrane pool drain 8 and the first check valve 11, and then use the flow valve 12 to control the tap water containing trace amounts of pharmaceuticals from the inlet Water pipe 1 to 4m 3 / m 2 h~16m 3 / m 2...

specific Embodiment approach 3

[0043] Embodiment 3: The difference between this embodiment and Embodiment 2 is that the concentration of trace pharmaceuticals in the tap water is below 10 mg. Other steps are the same as in the second embodiment.

Abstract

The invention discloses an assembled device for removing activated carbon and an ultrafiltration membrane in micro medical drugs in tap water and a method for removing micro medical drugs in the tap water, relates to a device and a method for removing micro medical drugs in the tap water, and aims to solve the problem that the conventional method for removing micro medical drugs in the tap water is expensive in price, not suitable for being popularized and poor in removing effect. The device comprises a water inlet pipe, a first granular active carbon column water outlet, a granular active carbon column, the ultrafiltration membrane, a pressure sensor, an ultrafiltration membrane pumping water pump, an ultrafiltration membrane tank, a fresh water box, a back washing water pump, a check valve, a flow valve, a fresh water box water inlet, an ultrafiltration membrane tank water inlet, a first granular active carbon column water inlet, a water drainage pipe and a fresh water box water outlet. The method for removing the micro medical drugs in the tap water comprises the steps of 1, filling modified granular active carbon into the granular active carbon column, and 2, treating the tap water containing the micro medical drugs. The device and the method can be used for removing the micro medical drugs in the tap water.

Description

technical field [0001] The invention relates to a device for removing trace medicines in tap water and a method for removing trace medicines in tap water. Background technique [0002] Medicines are widely used in daily life, but in recent years, the pollution of medicines has been found in tap water in residential areas, water in urban water supply pipe networks, and water in clean water tanks of water supply plants. Therefore, it is necessary to study an efficient and economical The treatment method is very necessary. Biological treatment is a low-cost treatment method, but the pharmaceuticals in water often have the characteristics of complex structure and poor biodegradability, and biological treatment is not suitable for tap water treatment; electrochemical technology, advanced oxidation technology, etc. The treatment effect of pharmaceuticals is remarkable, but the cost is high and it is not easy to popularize. [0003] Adsorption is a simple and effective treatment ...
