[0037] Preparation of biochar material

[0038] Dry and crush wheat (WS) and rice husk (RH) straws to a particle size of 2mm respectively. Weigh 12g of crushed wheat straws in a ceramic crucible (fill as much as possible to reduce the presence of oxygen), and put them in an oven (DGG-9023A) ,Shanghai Senxin Experimental Instrument Co., Ltd., China) Dry at 80℃ for 24 hours. Pass N to the surface of dried wheat straw 2 To remove oxygen, seal the ceramic crucible with aluminum foil paper, and then cover the ceramic crucible (oxygen limitation), and place the ceramic crucible in the muffle furnace (SX-GO7102, Tianjin Zhonghuan Experimental Electric Furnace Co., Ltd., China) to crack at C1 The lower limit of temperature is 2h for oxygen cracking. After the lysis, wash with distilled water repeatedly until the pH of the cleaning solution is neutral. After cleaning, place it in an oven and dry at 80°C for 24 hours to obtain biochar, which is sealed for later use. A...

[0043] Preparation of ball milled biochar

[0044] Place the biochar obtained in the above-mentioned Examples 1 to 6 in 500mL agate tanks, each tank was put into 1.8g biochar and 180g agate pellets with a diameter of 6mm, the agate tank was sealed and put into the planetary ball mill In the room temperature condition, the rotation speed is 300 rpm for 12 hours, and the rotation direction is changed every 30 minutes. The ball milled biochar is named as Table 2.

Abstract

The invention discloses a method for efficiently removing galaxolide in water, and belongs to the field of environmental protection water treatment. The method includes the steps: adding ball-milled biochar into the water to be treated; enriching the galaxolide in the water into the surface and pores of the ball-milled biochar by the aid of excellent physicochemical properties of the ball-milled biochar through adsorption and distribution functions to efficiently remove galaxolide pollutants in the water. Resourceful treatment of waste is realized to a certain degree by biochar preparation, and preparation of the ball-milled biochar has the advantages of simple process, low cost and high efficiency. Compared with other biochar modification methods (such as acid and alkali modification, andbiochar and nano-particle compounding), the method has the advantages that cost is saved, and secondary pollution is reduced. The HHCB adsorption quantity of the method can reach 2125mg/kg and is farhigher than that of corresponding original biochar (750mg/kg).

Description

technical field [0001] The invention belongs to the field of water treatment for environmental protection, and in particular relates to a method for efficiently removing carole musk from water. Background technique [0002] In the past decade, with the improvement of environmental analysis technology and the enhancement of people's environmental awareness, emerging micro-pollutants in the water environment are increasingly concerned by researchers around the world, such as pharmaceuticals and personal care products (Pharmaceuticals and Personal Care Products, PPCPs), endocrine disruptors (Endocrine Disruptors Chemicals, EDCs), etc. Low concentration (ng / L~μg / L order of magnitude), many types, and complex properties are important characteristics of micro-polluting organic matter. At present, many micro-polluting organic substances detected in water bodies have been proven to cause great harm to the human body, and some of them have even been identified or suspected as "three...
