Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of biofilm packing and its system for sewage treatment
Preparation Method.
Background technique
Bioanalysis be it is a kind of efficiently, the sewage water treatment method of environmental protection, and biofilm be important sewage disposal technology it
One, anti-shock loading is high, good denitrogenation and dephosphorization effect, will not generate sludge bulking phenomenon, and investment is low, operation and maintenance are simple, exists
Municipal wastewater process field is widely applied.Filler is the core of technology of biological membrane, and the quality of performance determines sewage treatment
Effect.Biologic packing material is generally with polypropylene, polyethylene and polyurethane etc. for substrate at present, by adding calcium carbonate, polyvinyl alcohol
It is formed etc. mineral-modified.The existing generally existing Active components distribution of filler is uneven, specific surface area is small, hydrophily and biology parent
It is poor with property, lead to that biologic packing material moistened surface, attached growth of microorganisms characteristic is not good enough, the biofilm time is long, and biofilm biomass is few, micro-
The problems such as biology is insufficient with filler tightness.
Discarded sea shells are mainly by 95% biology base calcium carbonate and 5% glycoprotein, polysaccharide, chitin, protein
Etc. material compositions, while also containing there are many microelements necessary to biology growing.The biogenic mineral material natural as one kind,
Shell is other than with good bioaffinity energy, due to the calcium carbonate and organic matter of its forming process inherently inorganic
The process of combination, this just makes shell compared with the inorganic matter of Calcium carbonate, is carrying out modified high-molecular material as active component
Material aspect has apparent advantage, does not on the one hand need to carry out complicated surface modification technology as inorganic filler, reduce
Preparation section reduces production cost, on the other hand also can achieve the purpose for significantly improving filler mechanical performance, such as Chinese patent
Application number 201511025718.7, invention and created name are：A kind of method of oyster shell powder modification biological filler.Tourmaline is one
Kind of crystal structure and the more complicated ring silicate crystalline mineral matter of chemical composition.Tourmaline being capable of spontaneous adjusting water body pH
Value reduces associated water molecules degree, improves microbe survival environment, stimulates dehydrogenase activity and improves the function such as denitrifying bacteria activity
Energy.Currently, by polypropylene, shell, tourmaline synthesis high-molecular biologic film filler research and application have no document report and
Patent disclosure.
Summary of the invention
The purpose of the invention patent is in view of the above-mentioned problems, using the hydroxyl on natural seashell biological substance surface, carboxyl etc.
Chemical active radical abundant reduces attached growth of microorganisms difficulty using the homologous affinity of microorganism and natural biomass,
A kind of large specific surface area is provided, is not easy to plug, easy to be filmed, cheap high-performance biofilm packing and preparation method thereof.This
The biofilm packing of invention has extremely strong hydrophily, bioaffinity and adsorptivity, has good wastewater treatment efficiency.
The invention is realized by the following technical scheme：
For the biofilm packing preparation method of sewage treatment, include the following steps：
The filler is made in following manner by shell, tourmaline, polypropylene, wherein shell, tourmaline, poly- third
The weight ratio of alkene is：Polypropylene：Shell：Tourmaline=80-90：1-15：1-20；
1) impurity for removing shell surface first impregnates 12-24h with the NaOH solution of 0.1-1.0mol/L, takes out with certainly
Water rinsed clean takes shell, tourmaline powder, polypropylene powder after cleaning respectively, and at 105 DEG C then drying crushes, and crosses 50-
300 meshes are spare；
2) conch meal is put into crucible, heats to 160-180 DEG C in Muffle furnace with 10-15 DEG C/min, constant temperature
Start to cool down after keeping 10-30min, rate of temperature fall is that 10-20 DEG C/min is obtained after temperature drops to room temperature by heating
The conch meal of reason；
3) mixed powder is added injection molding machine, adjusts temperature by each powder weight of weighing in a high speed mixer after mixing 5min
For degree to 160-180 DEG C, extrusion molding must squeeze out batten；
4) batten and appropriate amount of quartz sand will be squeezed out to be put into fluidized bed, so that spline surfaces and quartz sand particle is constantly rubbed with
The polypropylene film for removing particle surface package, obtains biofilm packing.
The discarded seafood shell be oyster shell, pearl shell, freshwater mussel shell, thick shell make a gift of or one of Mytilus galloprovincialis shell or
The a variety of mixture of person.
The tourmaline is that dravite, schorl, elbaite, tsilaisite are one such or a variety of
Mixture.
Helpfulness of the present invention：Biologic packing material obtained by the present invention contains shell and tourmaline can effectively improve the life of filler
Object activity, so that biologic packing material has good bioaffinity.The present invention makes full use of waste shell and tourmaline, can be effective
The mechanical performance for improving filler, extends the service life of biologic packing material.Shell is made in conjunction with tourmaline biology and filled out by the present invention
Material, further improves the specific surface area of filler, keeps the biofilm time short, and biofilm amount is big, while production technology of the present invention letter
It is single, it is lower to manufacture cost.
