Description
Technical field
The present invention relates to biomass environment adsorbing materials to dispose of sewage technical field.Be specifically related to a kind of modified peanut charcoal/aluminium polychloride mud composite adsorbing material.
Background technology
In recent years, the recycling of agricultural solid waste receives much concern.As a kind of main industrial crops, peanut is extensively planted in China, and a large amount of peanut shells thereupon produced are banked up in a large number as agricultural solid waste or burn.This not only causes the wasting of resources, produces a large amount of smog and CO, CO simultaneously
2deng material, harm ecological environment.Current, organic agriculture solid waste charring process is subject to people because of features such as its input is low, high efficiency, applied ranges and more and more pays close attention to.Product after the charing of organic agriculture solid waste---carbon granule can produce civilian charcoal and active carbon through further processing; It also can be used as soil conditioner and is applied to farmland, improves agricultural land soil quality.In addition, have scholar's research to show, organic-biological matter after charing process the charcoal made to air, soil and water body in pollutant there is good absorption property.
Surface modification is carried out to biological material, the surface nature of biological material is changed exactly by methods such as physical chemistry, change its pore structure, change its surface acidic-basic property, or introduce on its surface or remove some functional group and make living beings have special absorption property and catalysis characteristics.Usually, by the charcoal prepared after surface modification, there is better absorption property.
Copper water-supply pipe is the accessory substance in water supply plant precipitation process of coagulation, and its steady sources, output are large, and its main component comprises humus, silicate, organic matter and some metal hydroxides etc.At present, the most frequently used coagulant of water supply plant is aluminium polychloride, when adopting aluminium polychloride to carry out coagulating treatment as coagulant, because of in the copper water-supply pipe that produces containing a large amount of aluminium polychlorides, therefore be called aluminium polychloride mud.When the aluminium polychloride mud containing coagulant such as aluminium salt enters after in water body, the deposition of a large amount of aluminium salt can form harm to aquatile and benthon; And contained heavy metal also may pollute underground water in mud.In order to reduce the destruction of even eradicating waterworks sludge and causing environment, Chinese scholars has carried out large quantifier elimination to the recycling of aluminium polychloride mud, as studied its improvement recycling etc. to the removal of Phosphorus From Wastewater and mud using aluminium-containing sludge as adsorbent.
