Abstract
The invention discloses a modified activated carbon adsorbent. The modified activated carbon adsorbent is prepared from the following raw materials in parts by weight: 80 to 90 parts of coconut shell activated carbon, 80 to 85 parts of wooden activated carbon, 60 to 70 parts of coaly activated carbon, 20 to 25 parts of wheat straw, 10 to 15 parts of peanut shell, 30 to 40 parts of attapulgite, 5 to 10 parts of kaolin, 8 to 10 parts of vermiculite, 1 to 3 parts of methylcellulose, 0.5 to 1 part of sodium dodecyl benzene sulfonate and 2 to 5 parts of activator, wherein the activator is one or several kinds of sodium hydroxide, potassium hydroxide and calcium oxide. The modified activated carbon adsorbent disclosed by the invention has big specific surface area, big adsorption capacity, high degree of treatment, stable effect, free of secondary pollution, and low cost.
Description
Technical field
The invention belongs to adsorption technology field, be specifically related to a kind of modified activated carbon absorbent.
Background technology
Along with the quickening of urbanization process, the increase of urban population and the reinforcement of environmental consciousness, the discharge capacity of urban industry waste water and sanitary sewage is increasing, treatment rate of domestic sewage also improves year by year, the process of sewage be unable to do without adsorbent, active carbon is porous adsorbing material, there is abundant pore structure, higher specific area and very strong adsorption capacity, it is ideal environmentally friendly adsorbent, charcoal absorption is the physical absorption utilizing active carbon, chemisorbed, oxidation, the performance such as catalytic oxidation and reduction removes the method for treating water of water pollutant.But active carbon cost is higher, govern applying of active carbon.
Summary of the invention
The object of the present invention is to provide a kind of modified activated carbon absorbent, specific area is large, and adsorption capacity is large, and degree for the treatment of is high, effect stability, and can not produce secondary pollution, cost is lower.
The technical solution used in the present invention is, a kind of modified activated carbon absorbent, be made up of the raw material of following parts by weight: cocoanut active charcoal 80-90 part, wood activated charcoal 80-85 part, coal mass active carbon 60-70 part, wheat stalk 20-25 part, peanut shell 10-15 part, attapulgite 30-40 part, kaolin 5-10 part, vermiculite 8-10 part, methylcellulose 1-3 part, neopelex 0.5-1 part, activator 2-5 part, described activator is one or more in NaOH, potassium hydroxide, calcium oxide.
The present invention has the following advantages: specific area is large, and adsorption capacity is large, and degree for the treatment of is high, effect stability, and can not produce secondary pollution, cost is lower, is widely used in the advanced treating of Water purification and waste water secondary treatment yielding water.
