Description

A kind of preparation method of high efficiency absorbent-type dephosphorization agent
Technical field
The present invention relates to material for water treatment preparing technical fields, and in particular to a kind of preparation of high efficiency absorbent-type dephosphorization agent Method.
Background technology
Phosphorus is the one of the chief elements of life to be maintained in earth system, and constitute organism and participate in metabolic processes Essential element.But body eutrophication is may result in if phosphorus content is more than 20mg/L in water body, causes algae a large amount of Breeding, being decomposed after frond death can make water body generate musty and stink, influence the existence of the aquatiles such as fish.
Phosphorus-containing wastewater main source is:1, Phos waste water can be divided into according to the existing forms of phosphorus(Phosphate, polyphosphoric acid Salt)And organism P wastewater(Organic phosphorus compound is mixed in water);2, Cataloguing In Source mostlys come from various detergent, phosphatization The excretion etc. of waste water, the production process of agricultural fertilizer and human body.
The phosphorus in waste water is mainly removed by chemical coacervating precipitation method and bioanalysis at present.Bioanalysis such as A/O, A2/O, UCT Technique is mainly suitable for processing low concentration and organic phosphorus-containing wastewater.Chemical method mainly has coagulant sedimentation, crystallisation, ion to hand over The techniques such as absorption method, electrodialysis, reverse osmosis are changed, are mainly suitable for processing inorganic states phosphorus-containing wastewater, chemical precipitation method is due to dephosphorizing rate It is high and become common dephosphorization method.The discharge index of phosphorus is very low, and level-one A scale values are 0.5 mg/litre, so many sewage pass through All be difficult to after the biochemical treatment stage it is up to standard, this be many units with dephosphorization agent come the reason of supplementing dephosphorization.
Dephosphorization agent be to sewage carry out biochemical treatment after still cannot be up to standard when supplement medicament, function is in coagulation turbidity removing While remove total phosphorus, achieve the purpose that qualified discharge.Original sub-block flow is had no need to change in operation, need not add large size Water treatment building, it is simple and easy to do, it is economical and practical, it can get significant social and economic benefit.Currently, most of dephosphorization agent with Inorganic molysite, aluminium salt, calcium salt or iron aluminium calcium and magnesium compound based on, form metal phosphate precipitation, pass through the side of spoil disposal Formula removes, and phosphor-removing effect is good, but the dosage of product is big, utilization rate is low, sludge output is big, easily causes pipe-line equipment blocking.Largely The additive of metal object is unfavorable for biosystem growth, is unfavorable for sludge incineration or compost disposition, is easy to form secondary pollution, together When also increase processing cost.
Therefore, secondary pollution is not generated in there is an urgent need for a kind of phosphor-removing effects of research and development good, recyclable recycling, preparation process Sewage dephosphorization agent.
Invention content
The technical problems to be solved by the invention:Low for calcium content in dephosphorization agent common at present, specific surface area is smaller, Alkalinity cannot be satisfied the needs of partial crystallization reaction, and relatively low to the removal rate of phosphor in sewage, can not meet the defect of market demands, carries A kind of preparation method of high efficiency absorbent-type dephosphorization agent is supplied.
In order to solve the above technical problems, the present invention is using technical solution as described below:
A kind of preparation method of high efficiency absorbent-type dephosphorization agent, it is characterised in that specifically preparation process is:
(1)It weighs and crosses 80 mesh sieve after 65~70g sepiolites are ground, collect sieving sepiolite powder, then the sepiolite that will be sieved Powder and deionized water mixing are impregnated, and after settling, filtering removal sediment obtains filtrate, and filtrate is placed in baking oven and is done It is dry, obtain dried object;
(2)Continue dried object and mixed in hydrochloric acid being placed in beaker and stir, be dried after stirring, drying is placed in Muffle furnace Roasting, cooling discharging obtain modified meerschaum powder;
(3)It weighs 3~5g seventy flavors pearl pills and stirring and dissolving in 180~200mL distilled water is poured into the mixing of 1~2g polyethylene glycol, Lysate is obtained, then 0.8~1.0mL sodium carbonate liquors are added dropwise into lysate and are mixed, obtains aqueous deposit, control contains Water deposit pH is 8.1~8.6, continues to stir, and finally modified meerschaum powder and aqueous deposit are mixed, centrifugation point From, removal water phase, isolated loaded article;
(4)Scallop shell and molybdenum disulfide are mixed to be placed in grinder after grinding and cross 80 mesh sieve, collects sieving mixed-powder, incited somebody to action It sieves mixed-powder and silane resin acceptor kh-550 is mixed, obtain mixture, continue that mixture quality is added into mixture The Yoghourt of 8% glucose and mixture quality 0.5%, is fitted into fermentation tank, is sealed by fermentation, and after fermentation, takes out fermentation production Object, as modified mixed-powder;
(5)Loaded article, modified mixed-powder and absolute ethyl alcohol are mixed, obtain stirred suspension, then by stirred suspension It is placed in ultrasonic wave separating apparatus and is ultrasonically treated with lauryl sodium sulfate mixing, supersound process is placed in baking oven dry, cooling Discharging is to get high efficiency absorbent-type dephosphorization agent.
Step(1)The time that grinds is 10~12min, the mass ratio of be sieved sepiolite powder and deionized water It is 1:3, soaking time is 24~32min, and drying temperature is 75~85 DEG C, and drying time is 30~32min.
Step(2)The solid-liquid mass ratio of the dried object and a concentration of 0.8mol/L hydrochloric acid is 1:20, whipping temp is 80~85 DEG C, mixing time be 12~16h, drying time be 2~4h, calcination temperature be 400~420 DEG C, roasting time be 1~ 2h。
Step(3)The stirring and dissolving rotating speed is 200~240r/min, and the stirring and dissolving time is 32~40min, carbonic acid A concentration of 1mol/L of sodium solution, mixing time are 20~24min, and whipping temp is 45~50 DEG C, continues mixing time For 1~2h, the mass ratio of modified meerschaum powder and aqueous deposit is 3:1, the mixing time is 45~60min.
Step(4)The mass ratio of the scallop shell and molybdenum disulfide is 1:4, milling time is 5~7min, sieving mixing The mass ratio of powder and silane resin acceptor kh-550 is 5:1, the mixing time is 10~12min, and fermentation temperature is 37~42 DEG C, fermentation time is 9~11 days.
