specific Embodiment approach 1

[0025] Specific implementation mode one: combine figure 1 with figure 2 , this embodiment is a bio-enhanced water filtration treatment device that can be adjusted at low temperature, including a fixed frame 1, a low-temperature constant temperature water bath 4, a thermal insulation layer 5, a pre-cooling water inlet tank 6, a raw water tank 7, and a low-temperature constant temperature circulation device 8 , low-temperature circulation pipeline 9, solenoid valve 10, first peristaltic pump 11, flow meter 12, overflow pipe 13, first sealing sleeve 14, first-stage transmission water pipe 15, bio-augmented filter column 16, second-stage transmission water pipe 17. Second peristaltic pump 18, water outlet pipe 19, vent pipe 20, monitoring display 21, data transmission line 22, monitoring probe 23, packing bed 24, supporting layer 25, water distribution orifice plate 26, sampling port 27, second seal Sleeve 28, emptying pipe 29, water inlet pipe 30, third sealing sleeve 31, fourt...

specific Embodiment approach 2

[0048] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the materials of the bio-enhanced filter column 16 and the pre-cooling water inlet tank 6 are all stainless steel, and the material of the low-temperature constant temperature water bath 4 is plexiglass material or stainless steel material. Other steps are the same as in the first embodiment.

[0049] This embodiment is set in this way, which can increase the temperature conductivity, which is beneficial to keep the temperature in the pre-cooling water inlet tank 6 and the bio-augmented filter column 16 constant.

specific Embodiment approach 3

[0050] Embodiment 3: The differences between this embodiment and Embodiment 1 or 2 are: the overflow pipe 13, the low-temperature circulation pipeline 9, the first-stage water transfer pipe 15, the second-stage water transfer pipe 17, and the outlet pipe 19 and the air pipe 20 are made of PE pipe or silicone pipe, and the outside of the overflow pipe 13, the low-temperature circulation pipeline 9, the first-stage water transfer pipe 15, the second-stage water transfer pipe 17, the water outlet pipe 19 and the air pipe 20 are all wound Rubber-plastic sponge or polyethylene insulation material. Other steps are the same as those in Embodiment 1 or 2.

[0051] The purpose of such setting in this embodiment is to keep the water temperature of the water in and out of the low temperature constant temperature water bath 4 and each process unit of the water treatment device constant.

Description

technical field [0001] The invention relates to a water treatment device. Background technique [0002] With the continuous advancement of my country's urbanization process, the pollution of ammonia nitrogen and organic matter in drinking water sources has become one of the main environmental problems. In view of the impact of micro-pollutants on water supply safety, in the "Drinking Water Hygienic Standard" (GB5749-2006) promulgated by the state, the control of organic pollutants, ammonia nitrogen, iron, and manganese content is also more stringent. At present, the conventional water purification process (coagulation-sedimentation-filtration) adopted by urban water supply treatment plants is difficult to effectively remove micro-pollutants in water source water. Among many drinking water advanced treatment technologies, bio-augmentation filter is an effective method to treat micro-pollutants in slightly polluted water source water. According to the type of filler, bio-enh...
