specific Embodiment approach 1

[0018] Specific embodiment one: the method for removing organic matter in micro-polluted water source water based on the biological purification filter column of the present embodiment is carried out according to the following steps:

[0019] 1. Construction of the biological purification filter column system: the biological purification filter column system consists of filter column 1, first water tank 2, second water tank 3, third water tank 4, first water pump 5, second water pump 6, third water pump 7 and The mixer 8 is composed of a support layer 1-1 in the lower part of the filter column 1, and a filter material layer 1-2 above the support layer. An overflow port 1-3 is set at the upper end of the filter column 1, and Water outlet 1-4 is set at the bottom of 1, sampling port 1-5 is set on the side wall of filter column 1; first water pump 5 is set on the pipeline between first water tank 2 and mixer 8, second water tank 3 and mixer The second water pump 6 is arranged on ...

specific Embodiment approach 2

[0025] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in Step 1, the supporting layer 1-1 is supplemented by stone grains with a particle size of 30-50 mm; other aspects are the same as Embodiment 1.

specific Embodiment approach 3

[0026] Embodiment 3: This embodiment is different from Embodiment 1 or 2 in that the filter material layer 1-2 in step 1 is quartz sand, and the particle size of the quartz sand is 10-20 mm; the others are the same as Embodiment 1 or 2.

Abstract

A method of removing organic substances in water of a micro-polluted water source on the basis of a bio-purifying filter column mainly solves a technical problem that in the prior art, the removal rate of removing the organic substances in a micro-polluted water source through a bio-process is low. The method includes the steps of: 1) establishing a bio-purifying filter column system; 2) in the bio-purifying filter column system, culturing heterotrophic microorganisms that can degrade the organic substances and Mn-oxidizing microorganisms that can catalytically oxidize manganese; 3) operating the bio-purifying filter column system. The method is high in removal efficiency on the organic substances in the micro-polluted water source and achieves high-effective and stable removal of organic substances in the water source. The content of the organic substances in outlet water is significantly lower than national drinking water standard. The method has advantages in practical engineering applications.

Description

technical field [0001] The invention relates to a method for removing organic matter in slightly polluted water source water, belonging to the field of drinking water treatment. Background technique [0002] Water is an indispensable resource in human survival and production activities. With the rapid growth of population, the rapid development of economy and the continuous improvement of people's living standards, the human demand for water resources is gradually increasing. However, with the use of a large amount of pesticides and fertilizers in the process of industrial and agricultural production, and the discharge of domestic sewage and industrial "three wastes" without strict treatment, organic pollutants detected in water source water are increasing, including pesticides, chemical raw materials, drugs, Personal care products and endocrine disruptors, etc. Among them, although the concentration of many pollutants is low, they are difficult to biodegrade and extremely...
