Compared with the prior art, the biological stuffing preparation technology for treating the water has the characteristics of easy raw material purchase, simple process, low production cost, easy processing, high microorganism growth speed, short bacteria cultivation time, favorable water processing effect, etc. Thus, the preparation technology has wide popularization and use value.
Description
1, technical field
The present invention relates to a kind of production technology of water treatment filler, specifically a kind of preparation method of water-treatment biological filler.
2, background technology
Current, in this field of water-treatment biological technology, mainly contain these two kinds of water technologies of activated sludge process and biomembrance process.Activated sludge process is present widely used a kind of water technology, but because there are some problems in this method, suspension concentration as mixed solution in the biological reaction tank can not be too high, too high can influence effect of settling, and be easy to generate sludge bulking, phenomenon is clamminess, cause the dehydration difficulty, move problems such as unfavorable; Biomembrance process is a biological contact oxidation process, its ultimate principle is that soft-filler, semi soft packing and plastic pvc hollow ball etc. are suspended in the water, by realizing treatment function after the steps such as inoculation, cultivation and domestication, this method also has its insufficient one side, promptly this method is uncontrollable to active biomass, operational flexibility is poor, and it is high that complexity, maintenance difficult, cost be installed.
3, summary of the invention
The purpose of this invention is to provide a kind of preparation method who realizes a kind of water-treatment biological filler of long-term water purifying by the mud backflow that a kind of technology advantage simple, that combine activated sludge process and these two kinds of water technologies of biomembrance process forms.
The objective of the invention is to realize in the following manner, a kind of preparation method of water-treatment biological filler is to contain SiO
2And Al
2O
3Diatomite be raw material, after the pulverizing, grinding particle size was calcined 2.5-3.0 hour under 950-1050 ℃ high temperature at the ore deposit soil particle between the 50-60 order, when being cooled between 85-100 ℃, the ore deposit soil particle put in the retort and adding the Na that accounts for ore deposit soil raw material gross weight 0.5-0.8%
2CO
3With the short long agent of the microorganism of 8-12ppm, to react after 3.5-4.5 hour, drying is handled and is finished product.
Contained SiO in the refined biometric filler
2And Al
2O
3Weight proportion be respectively 60-80% and 15-20%.
The short long agent of microorganism is cobalt element and cobalt compound any one or boths' a mixture.
Biologic packing material behind the high-temperature activation is the particle that contains a large amount of small pores, and its specific surface area is at 400-700m
2Between/the g, proportion is between 0.9-0.95.
The invention has the beneficial effects as follows, adopt the Filler for water purification of this explained hereafter, combine the advantage of activated sludge process and biomembrance process, defective and deficiency that these two kinds of methods exist have been avoided cleverly, throw in the filler of different amounts according to the quality of water quality, reflux by mud and realize the function of filler life-time service.
The function of this biologic packing material and characteristics:
1) biological concentration height: this biologic packing material can be controlled add-on according to water quality requirement and generally use 10000-15000mg/L, reach as high as 30000mg/L, because biological concentration height, organism there is stronger oxidation capacity, separates the ability of falling, COD, BOD clearance are more than 95%, and shock-resistant ability is strong simultaneously.
2) mass-transfer efficiency height, power consumption are less, power economizes, because filler directly drops in the pond and uses, mix fluidisation fully with gas, water when aeration, and the utilization ratio of cutting and collision raising oxygen is generally more than 90%.Microbial film can come off renewal voluntarily and need not to add atm number, and biological metabolism is fast, keeps higher biological activity, improves the clearance to COD.
3) bacterial growth is fast, the spawn culture time is short, because the physical features that this filler has and the performance of component, give the good condition and the place of rapid growth of bacteria and existence, therefore the microbial culture time was generally 15-20 days, can shorten 10-15 days (under the same culture condition) than other biologic packing material spawn culture.
4) synchronous digestion-anti-digestion is arranged, reach the purpose of denitrogenation dephosphorization, this filler has performances such as absorption, flocculation, network, its zoogloea flocculation in service is bigger, making that autotrophic type digestion bacterium and heterotroph are counter digests bacterium and can exist simultaneously, thereby digestion-anti-digestion is taken place synchronously, reach the purpose of denitrogenation dephosphorization.Its deoxidation, dephosphorizing rate are more than 95%.
5) this biologic packing material can be used in various sanitary sewages and Industrial Wastewater Treatment.
4, embodiment
Embodiment 1:
Choose an amount of high-quality diatomite, after the pulverizer pulverizing, filter out ore deposit soil particle between the 50-55 order by sifting machine, this particle was rendered in the High Temperature Furnaces Heating Apparatus high temperature sintering 2.8 hours, temperature is controlled at about 1000 ℃, after calcination finishes, allows it naturally cool between 85-90 ℃, then it is rendered in the retort, and add the Na that accounts for ore deposit soil raw material gross weight 0.5-0.7%
2CO
3With the short long agent cobalt of the microorganism of 10ppm, react after 4 hours, render to interior processing of moisture eliminator at last again and be finished product in 3 hours.
Embodiment 2:
Choose an amount of high-quality diatomite, after the pulverizer pulverizing, filter out ore deposit soil particle between the 55-60 order by sifting machine, this particle was rendered in the High Temperature Furnaces Heating Apparatus high temperature sintering 3 hours, temperature is controlled at about 1000 ℃, after calcination finishes, allows it naturally cool between 95-100 ℃, then it is rendered in the retort, and add the Na that accounts for ore deposit soil raw material gross weight 0.6-0.8%
2CO
3With the short long agent cobalt oxide of the microorganism of 12ppm, react after 4.5 hours, render to interior processing of moisture eliminator at last again and be finished product in 3.5 hours.
Its using method of biologic packing material by this explained hereafter is similar to activated sludge process, directly drop in the pond and get final product, because filler itself has biological nature, so not only can promote microbial growth, and can provide good growth place for microorganism, and can also adjust according to change of water quality simultaneously, both had the advantage of above-mentioned activated sludge process and biomembrance process, deficiency and the defective of having avoided aforesaid method to exist again are a kind of comparatively ideal water treatment micro-organism fillers.
The preparation method of a kind of water-treatment biological filler of the present invention is compared with existing technology, and it is easy to have a raw material Purchase, technology is simple, production cost is low, be easy to processing, fast, the bacterial classification incubation time of growth of microorganism speed The characteristics such as short, water treatment is effective, thereby, have good value for applications.
