Moreover, there have been many successful examples of practical application in industrial production, such as the production of biochemical products such as Gao Duo Xun Xunzhong, 6-APA ’L-Atmosphere. The typical high-molecular materials used for immobilization of the support are polyacrylamide, polycarryenamide, K_carrageenan, sodium alginate, and agar. Polypropylene amide is often cheaper than other polymers. However, it is difficult to make spherical particles that are good for general continuous reactors, and its monomer molecules and polymerization promotion are all toxic, which is not conducive to the immobilization of living cells of microorganisms. Although the staghorn vine wins Chengrong Road and has low toxicity, its higher price is its main disadvantage. Although the rattan gum is also easy to form into a spherical shape, but in the reaction solution containing cations such as phosphoric acid, noodles and bells, the strength of the gum® is quite undisturbed, and even disintegrates. In addition, win; The body's selective strength is too weak and unsuitable for long-term operation. Therefore, if the immobilized bacteria vessel technology is to be effectively applied to the industrialization process of biochemical commodities, it is the most recently recognized Θ wastewater treatment field. The success level of its success is due to its non-toxicity to olive organisms, low cost and Development of projectile materials with strong mechanical strength. Polyvinyl a] cohol (Polyvinyl a] cohol, (PVA) ’is a water-soluble tree made from vinegar and c chan monomers by polymerization and alcoholization. P v A is not toxic or even recognized by the human body as harmless, easy to shape, high in mechanical strength, and is a low-cost industrial raw material for childbirth. Therefore, it is very suitable as a support for immobilized cells.

Description of invention () Existing PVA immobilized cell technology and shortcomings In recent years, the patent publications of Ou Meiwen Factory and Japan have published various technologies for the immobilization of microorganisms using PVA. For example, after combining PVA aqueous solution with microorganisms, freeze-drying is applied. Or freeze fixation method (Japanese Patent Laid-Open No. 57-14129, Japanese Patent Laid-Open No. 61-139385) ○ Using ultraviolet irradiation to form a photo-crosslinking (phot〇Crosslinking) structure of the lacquer method (Japanese Patent Japanese Patent Laid-Open No. 1 -454372). In addition, there is also a glue technology that puts a mixed solution of PVA aqueous solution and microbial cells in contact with roe deer and boron solution to form a bridge structure (Japanese Patent Laid-Open Patent. Although the above method can obtain high strength The colloid is used as a carrier of immobilized bacteria, but there are still many shortcomings that need to be improved. In the freeze dry salamander method, the material must be kept frozen at a low temperature of -3〇 ~ -8〇t: Dry and dehydrate to a certain water content, this kind of The steps of freezing-thawing-dehydration are not only time-consuming, but also complicated and complicated, and require energy. The photocrosslinking method is mostly based on the method used when making the film, which is not conducive to the use of general bacterial immobilization procedures . In addition, in the PVA · boric acid method, the mixture of microorganisms-? "Must be immersed in boron for I2 ~ 24 hours to obtain a very strong colloid, otherwise the glue is completely fragile. In summary, the above-mentioned existing 抆 术The common shortcomings are: first, the fixed procedure takes a long time, the work is complicated, and it requires large production equipment to mass-produce, which leads to increased production costs and low productivity. Second, low temperature, vacuum and high temperature It is not suitable for the environment where microorganisms live. Especially boron is more toxic, and the long-term production sequence may cause a decrease in the activity of microorganisms. Kitano Kiyoshi once proposed to use a mixture of PVA and microbial bacteria in a sulfur solution The method of contact to improve the above shortcomings (Japanese Patent Laid-Open Sho-4-(Precautions for the first Μί * 卄 面 , then write a book π) Pregnancy CNS > T4 specification (210X297mm) マ テ ギ ン デ テ ム 'f Bureau M Gong > · «* ·»? Cooperation Du Xi draft 199906 V. Description of the invention () 64-549〇, 64 is 1). Although this method effectively shortens the time required for the immobilization process, the concentration of the gel solution used is quite high, and it must be performed with a 30% uranium sulfate or ammonium sulfate solution. If the concentration is too low, the particles are not easy to form and the strength is not Therefore, the required material cost is high; the high i concentration in the gel forming process also has a bad influence on the biochemical activity of olive. The method for forming the boric acid-phosphoric acid second companion segment proposed by the present invention is first set In: 3¾ to roe and roll degree of boric acid solution in the sister time to shape, and then strengthened in 3 · 20% phosphate alliance solution. It is quite easy to form, and the price of phoenix is low. It is also a source of microbial energy metabolism and is not biotoxic. In addition, the use of low concentrations of porphyrins at low cost. Moreover, it has more colloidal initial properties than the sulfur-breaking alliance method. The purpose of the present invention is to propose a simple manufacturing process, low cost, and high water resistance, strong mechanical strength, and excellent biochemical activity in a short time. PVA gel immobilized microorganisms or enzymes, and it is widely used in the field of wastewater treatment and biochemical industry. SUMMARY OF THE INVENTION AND CHARACTERISTICS The present invention provides an improved preparation method of polyenol microbial enzyme-immobilized carriers' The mixture formed by polyglycene and microorganisms or enzymes is subjected to gelation treatment in a basic aqueous solution with a concentration of 3% by weight to saturation to produce a gel sphere. The improvement is that the gelation treatment The boring time is 10 minutes to 2 hours, and the gel spheres are then immersed in 32% by weight phosphoric acid or phosphoric acid aqueous solution for more than 30 minutes to harden them to obtain polyethylene paper ft scale.

The principle and special feature of the method of the present invention is to use the argonoxy group in the PVA molecule and the ionic silver bridge between the molecules to shape it; then, the less strong gel is immersed in phosphoric acid or phosphoric acid In the basket solution, the colloidal hardening reaction is carried out between PVA and Beijun or phosphoric acid to harden the colloid to obtain an immobilized compound with strong mechanical strength and almost no damage to the biochemical activity of olive organisms or enzymes. The production process of the present invention can be represented by the first font. The PVA used in the present invention has a degree of alkalinity of 70 or more, a degree of polymerization of 1,000 to 3,000, and a degree of alkalinity of 9S% or more and a degree of polymerization of 1500 to 20,000 are more suitable . If the degree of polymerization is low, the colloid is not finalized, and if it is too high, the viscosity increases and it is not easy to handle. The PVA is mixed with the olive or enzyme in the form of an aqueous solution, and the appropriate PVA concentration is 10 to 20% by weight. The formation time of the bezoic acid is preferably about 15 to 30 minutes in a saturated bezoic acid aqueous solution. The preferred concentration of phosphoric acid or phosphoric acid aqueous solution is 5.15 heavy child *, and the immersion time takes about 1 to 2 hours, that is, to obtain the ideal finished product. Sodium phosphate, argonine phosphate, dihydrophosphate, potassium phosphate, potassium phosphazide, dipotassium linate, linacid acid, linjun I, or linjun di I ammonium are used as the aqueous solution T of phosphazone. Another preferred embodiment of the method of the present invention is to mix the boric acid with an aqueous solution of phosphoric acid or phosphoric acid, while simultaneously performing the gelatinization and hardening, the time is about 30 minutes to 3 hours, with I-2 hours as the comparison The best feature of the present invention is that the colloidal basic silver is first established in the boric acid solution. Since the contact time is not long, the possible damage of boric acid to olive organisms or enzymes is minimized. ~ 24 hours, Japanese Patent Laid-open Zhao 61-100193).
