Background technique
Heavy metal pollution at present brings great harm to human survival, it mainly includes environmental pollution and human injury,
Various regions heavy metal pollution event also emerges one after another, and causes extreme loss to people's lives and properties.With the propulsion of global industry,
Heavy metal pollution problem is becoming the serious problem that whole mankind's survival and development must face.In China, industrial pollution is
Cause China 1/5 arable land, 80.1% river,lake and reservior substrate by heavy metal pollution, it is serious about water body and heavy metal-polluted soil
The social event for endangering human health takes place frequently.It is " heavy metal-polluted that State Council in 2011 has given an written reply first " 12th Five-Year Plan " ad hoc planning
Contaminate the planning of integrated control " 12th Five-Year Plan " ", during " 12th Five-Year Plan ", state key supports the heavy metal pollutions such as lead, mercury, cadmium, chromium, arsenic
The projects such as Enterprise Integrated regulation, the demonstration of prevention and cure of pollution new technology and popularization.Heavy metal pollution is administered firstly the need of industrial from control
The discharge of waste water is started with, and then carries out the comprehensive treatment to contaminated water body, flue dust, soil, solid waste etc..It is general at present
Heavy metal ion in industrial wastewater is removed using chemical precipitation method, electrolysis method, absorption method, ion-exchange, membrane separation process etc.,
But treatment effect is undesirable, processing cost is high, and global heavy metal pollution problem further deteriorates, although heavy metal pollution
It is so serious that harmfulness is contaminated to the mankind, but it is helpless always that the mankind are effectively administered for it.People always search for thus
A kind of cost is relatively low, can effectively adsorb the material of heavy metal to administer heavy metal pollution.
Summary of the invention
The technical problem to be solved by the present invention is to the shortcomings that overcoming the above prior art: provide that a kind of cost is relatively low, can
The effectively preparation method of the porous ceramic film material of absorption heavy metal.
Technical solution of the invention is as follows: it is a kind of for adsorbing the preparation method of the porous ceramic film material of heavy metal,
The following steps are included:
1) preparation of pug: following raw material is added prepares pug in kneading machine mixing 10-20 minutes first: raw material A with
Parts by weight are calculated as: 30-70 parts of clay, 15-37 parts of kaolin, 5-10 parts of montmorillonite, 1-8 parts of sesbania powder；Raw material B is to account for raw material
The water of A total weight 20-50%；
2) phosphorus compound solution is prepared: the phosphorus compound of 20-40 parts by weight being dissolved in the water of 30-60 parts by weight and being prepared into
To phosphorus compound solution；
3) it is kneaded: the prepared phosphorus compound solution of step 2 being put into the pug in step 1), again with kneading machine
It is kneaded 20-30 minutes；
4) ceramic body forms: being green body by pug extrusion molding made from step 3)；
5) drying of ceramic body: green body made from step 4) is dried at 200-220 DEG C to moisture weight percentage
Content is lower than 0.8%；
6) ceramic body is burnt into: the dried green body of step 5) being burnt into, firing temperature is 700-1000 DEG C.
The phosphorus compound is one or more of monoammonium phosphate, triammonium phosphate, calcium monohydrogen phosphate.
The clay is Anhui clay.
The beneficial effects of the present invention are: the porous ceramic film material that the present invention is used to adsorb heavy metal has porosity, high ratio
Area, high mechanical strength, high physical adsorbability, high chemical adsorptivity, chemisorption wide adaptability, and due to the former material of the method
Material is largely natural minerals and production technology is ceramic process, and preparation method is simple, so production cost is low, regeneration rate
Height, material of the present invention are particularly suitable for the reparation of contaminated by heavy metals agricultural land soil, to the soil by material of the present invention absorption
Contained heavy metal ion not only can be sufficiently adsorbed in earth, but also the crops such as phosphorous, calcium, magnesium, potassium are raw because of material of the present invention
Long necessary element, it is possible to nutrient is provided for farmland, thus can be more raw more suitable for crops than contaminated by heavy metals preceding soil
It is long.
