Abstract
The invention relates to a kind of filtering agent for absorbing granule in form of concave-convex bar and its production method. The essentials of the invention can be described as follows: using concave-convex bar stone clay as the raw materials, deal it with the acidizing way and then desiccate it; after adding the paddy skin to it, make them with the steps of milling, granulation and roasting; finally, the product is a filtering agent for absorbing granule in form of concave-convex bar. The product of the invention has complete effictiveness of acidation and has no secondary pollution. The surface of the granule is rough and hard, is lager than the surface area, and the void ratio of it is high. Moreover, it has excellent absorbing and decolors ability, great filtering and pollution stemming ability, long service life, and low water usage in back washing. And also it contains no hazardous component to our human body, otherwise its production technology is easy and its cost is low. The product can be used mainly for the sewage disposal in the industrial field of chemical engineering, brewing, medicine, paper manufacture and so on. And also it can be applied to the sewage disposal of the purgative water and the urban channel.
Description
Technical field
The present invention relates to the environmental protection field, be specifically related to a kind of concave-convex rod particle absorption filter agent and production method thereof.
Background technology
Along with development of industry and agriculture, strengthen scientific and technological development to efforts at environmental protection, become the important topic of relevant scientific research department, the various new products that are used for environmental protection constantly put into production, have obtained achievement preferably.Be used for chemical industry at present, brewage, the absorption filtering material kind of industry sewage disposal such as medicine, papermaking is a lot, mainly contain: activated carbon, haydite, resinae, quartz sand, diatomite, zeolite, bentonite and Concave-convex clay rod etc.
Chinese patent publication number CN1394664, open day is on February 3rd, 2003, name is called " concavo-convex rod spherical filtering material ", discloses a kind of " being used for the various liquids and gases purification filtering material that temperature is not higher than 400 ℃ ".80% attapulgite that it is characterized in that total amount is a major ingredient, participates in the manganese ore of total amount 6% again, 5% V Soda, 3% titanium dioxide, 6% the powder of foaming perlite.Be processed into 0.2mm～1.5mm diameter ball.
Concave-convex clay rod is a kind of moisture magnesium alumino metasilicate salt mine, and it has performances such as good adsorption, decolouring, because the inner porous of Concave-convex clay rod road, specific surface is big, can reach 500m
2More than/the g, most cation, hydrone and a certain size organic molecule all can directly be adsorbed in the duct, and stable electrochemical property is difficult for being flocculated by electrolyte, has good stability in high temperature and salt solution.
Measure from production practices, Concave-convex clay rod is being used for technology such as sewage disposal, and acidization should be finished before causing particle, helps fully complete activation of Concave-convex clay rod, avoids secondary pollution; The concavo-convex rod spherical material that roasting is shaped adds the technology of soaking in the sulfuric acid, and when being used for industrial production in enormous quantities, operation easier is bigger; Concave-convex clay rod is in forming particle, and the volume in its granule interior duct needs further to expand.
