Description
Technical field
The invention belongs to water treatment coagulant field, especially, relate to a kind of modified Pericarpium Musae coagulant as raw material with Pericarpium Musae and inorganic elements.Moreover, it relates to the preparation technology of above-mentioned modified Pericarpium Musae coagulant.
Background technology
Coagulation process is one of core process of paying close attention to the most in domestic and international waste water and Water purification, there is simple, efficient, economic dispatch advantage, and coagulant is the main substance of coagulation process, its coagulability and the sludge components of generation are most important for the subsequent treatment etc. of single coagulation process effect or even the main body of whole water factory or advanced treatment process effect and cost, mud.Therefore, nontoxic, efficient, economic coagulant research and development and application just become important research content and the focus of water-treatment technology field.In the last few years, coagulant was very rapid in China's development, and kind gets more and more, and research is also in variation.Inorganic, organic, microorganism and the big class of compound coagulant four can be divided into by chemical constituent coagulant.Inorganic coagulant price is relatively low, and stability is preferable, and tool has great advantage, but biological and environment are all had a certain degree of negative effect.The feature that synthetic organic polymer coagulant has efficiently, consumption is few, but residue will also result in the biggest harm to biological and environment.Microorganism coagulant is the most nontoxic, but prepares from it, stores and be respectively provided with unstability to use, is therefore also substantially at conceptual phase at present, promotes the exploration needing remain for longer period of time apart from its scale.Natural organic high-molecular physical resources are abundant, cheap, degradable, nontoxic, there is good environmental acceptance, and for the former water that toxicity is less or nontoxic, the mud that water produces after processing completely can be with farmland reuse, obtained the extensive concern of countries in the world water treatment field expert the most in recent years, but stability bad be the intrinsic weak tendency of such coagulant.Therefore by natural organic high-molecular is inorganic with other or organic element organically combines, prepare the compound coagulant that stability is preferable, effect is more excellent and be always the research direction of such coagulant.
Relatively low with the cost that garbage prepares coagulant for primary raw material, and meet the thinking of the treatment of wastes with processes of wastes against one another, the most much studied, and achieved a large amount of achievement.Agriculture and forestry organic waste material is in recent years at the range of application expanding day of water treatment field, the such as application of rice husk, rice straw, straw, corn stalk, Pericarppium arachidis hypogaeae, bagasse, fruit peel etc..Pericarpium Musae is the one of agriculture and forestry organic waste material, is the outside rind of Fructus Musae, and its weight can account for about the 40% of its fruit weight.Agricultural industrialization structure there occurs that great changes, banana production are significantly increased therewith in recent years, and within 2014, China's Fructus Musae total output reaches 11,790,000 tons, thus results in abandoning of a large amount of Pericarpium Musae, and environment causes a certain degree of negative effect.Pericarpium Musae have also been obtained in water treatment field and pays close attention to significantly, but relates generally to adsorptivity about Pericarpium Musae in the application of water treatment field and directly utilize two broad aspect at present.There are some patents utilized about Pericarpium Musae adsorptivity both at home and abroad, such as: a kind of Pericarpium Musae modified activated carbon diatomite particle for desulfurization and dedusting and preparation method thereof (CN201510191618.5), a kind of preparation (CN100406396C) of pyromellitic acid anhydride modification Pericarpium Musae adsorbent, Pericarpium Musae is utilized to prepare the method for ammonia nitrogen adsorbent and the application (CN201310168967.6) of ammonia nitrogen adsorbent, the dye sorbent (CN201210121603.8) that a kind of Pericarpium Musae is made.Wherein CN 100406396C provides a kind of with Pericarpium Musae as primary raw material, the preparation method of the PMDA modification Pericarpium Musae adsorbent with PMDA as modifying agent；CN201310168967.6 provides one only by the broken washing by soaking of dehydration, utilizes the method that Pericarpium Musae prepares ammonia nitrogen adsorbent；CN201210121603.8 provides a kind of method using fermentation method that Pericarpium Musae is prepared dye sorbent.Also some are had to directly utilize the patent of Pericarpium Musae about water treatment procedure both at home and abroad at present, such as: utilize the method (CN201210009635.9) of Pericarpium Musae processing waste water containing chrome, utilize Pericarpium Musae to cook liquid and remove the method (CN201110442551.X) of Microcystis aeruginosa in water body.Above-mentioned all it is not directed to a kind of modified Pericarpium Musae coagulant as raw material with Pericarpium Musae and inorganic elements about Pericarpium Musae in the application technology of water treatment field, is also not directed to the preparation technology of above-mentioned modified Pericarpium Musae coagulant.
