Problems solved by technology

The invention reduces the production cost to a certain extent by using straw, but during the carbonization process of straw, the surface can form mesopores and macropores with better adsorption capacity, resulting in a decrease in its adsorption capacity, making it difficult to purify water.

Abstract

The invention discloses an efficient water purification activated carbon. The efficient water purification activated carbon is obtained by performing normal pressure impregnation and high pressure impregnation on coarse shaddock ped powder in an activator, carbonizing the powder under nitrogen protection, and acidifying the product. Compared with the prior art, the efficient water purification activated carbon disclosed by the invention promotes the activator to penetrate into the internal structure of the coarse shaddock ped powder through the high-pressure impregnation to enhance the impregnation effect; a series of cross-linking, dehydration and polycondensation are performed at a high temperature in the later stage, so that the activated carbon with a large specific surface area and multiple surface functional groups is prepared. The efficient water purification activated carbon disclosed by the invention can effectively filter out impurities in water tanks to high iodine adsorption value, specific surface area and pore volume, has remarkable antibacterial effect, can be used as a filter element of water purification equipment for a long time, is low in cost, high in adsorptioncapacity and good adsorption performance, and cannot cause secondary pollution.

Description

technical field [0001] The invention relates to the technical field of activated carbon, in particular to a high-efficiency water-purifying activated carbon and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, the increase of urban population and the strengthening of environmental protection awareness, the discharge of urban industrial wastewater and domestic sewage is increasing, the rate of urban sewage treatment is also increasing year by year, and the sludge generation rate of sewage plants is also increasing sharply. Water treatment agents mainly include chemicals required for cooling water and boiler water treatment, seawater desalination, membrane separation, biological treatment, flocculation and ion exchange, such as corrosion inhibitors, scale inhibitors and dispersants, bactericides and algicides, flocculants , ion exchange resins, purifiers, cleaning agents, pre-membrane agents, etc. [0003] Due to its huge spec...
