Problems solved by technology

[0003] At present, the methods used by domestic sewage treatment plants to remove organic micro-pollutants in water mainly include traditional treatment processes such as activated sludge process, chemical oxidation, photocatalysis, adsorption, coagulation and sedimentation, etc. The treatment effect of pollutants is not good, and there are problems such as high treatment cost, easy to cause secondary pollution, and complicated treatment process
In addition, although common aeration devices and ecological floating beds in natural rivers can effectively improve water quality, they have little effect on the removal of organic micro-pollutants

Embodiment 1

[0047] A method for preparing an adsorption packing synergistically bioactivating a permeable reaction column, comprising the following steps:

[0048] S1 ingredients: cut 8g of bamboo into small pieces, clean them, dry them in an oven at 40°C, and then crush them with a pulverizer to make bamboo particles with a particle size of 0.05-0.1mm;

[0049] S2 activation: the crushed bamboo particles were treated with 100 mL of MgCl with a concentration of 0.5M 2 ·6H 2 O and FeCl 3 ·6H 2 The mixed solution of O was soaked for 12 hours, the temperature was kept at 60°C, and magnetic stirring was continued at 2000 rpm;

[0050] S3 drying: the MgCl obtained in step S2 2 -FeCl 3 - Filtration of biological material aggregates, and the filtered solid particles are gently heated to dryness at 105 °C;

[0051] S4 calcining: put the solid particles obtained in step S3 into a tube furnace, 3 The flow rate of / min is continuously fed into N 2 , so that the solid particles are always in ...

Embodiment 2

[0059] The preparation method is the same as in Example 1, except that the biological material in step S1 is changed to wood.

[0060] The results showed that the removal rate of atrazine, a model organic pollutant, was 91.21% for the prepared adsorption packing combined with bioactivation permeable reaction column.

Embodiment 3

[0062] The preparation method is the same as in Example 1, except that the biological material in step S1 is changed to coconut shell.

[0063] The results showed that the removal rate of atrazine, a model organic pollutant, was 93.58% for the prepared adsorption packing combined with bioactivation permeable reaction column.

Abstract

The invention relates to an adsorption filler synergistic biological activation permeable reaction column as well as a preparation method and application thereof. The adsorption filler synergistic biological activation permeable reaction column is prepared from natural biological materials rich in cellulose, hemicellulose and lignin such as bamboos, coconut shells and wood through the steps of batching, activation, drying, calcination, inoculation, column packing and the like. The adsorption filler synergistic biological activation permeable reaction column is prepared and is used for removing organic micropollutants in natural water. Compared with the prior art, agricultural wastes are recycled, the raw materials of the reaction column are low in cost, easy to obtain and wide in source range, the hidden danger of the agricultural wastes to the ecological environment is solved, and good environmental benefits are achieved; the prepared permeable reaction column also has the advantages of high pollutant removal efficiency, strong adaptability, convenience in operation management and operation and the like, and has a bright engineering application prospect.

Description

technical field [0001] The invention relates to the technical field of water pollution control engineering, in particular to a permeable reaction column capable of effectively removing organic micro-pollutants in natural water bodies, and in particular to an adsorption filler synergistically activated biologically activated permeable reaction column and its preparation method and application . Background technique [0002] Natural or synthetic organic pollutants in water bodies have posed a serious threat to my country's ecological environment and national health. At present, the organic pollutants that are frequently detected in natural water bodies include polycyclic aromatic hydrocarbons, pesticides, polychlorinated biphenyls, perfluorosulfonyl compounds, polybrominated diphenyl ethers, etc., and a large part of them are persistent organic pollutants. The water environment often has characteristics such as low concentration, high toxicity, and refractory degradation, so ...
