Industrial Application Field The present invention provides a novel method for removing bacteria, more specifically, a method for removing bacteria present in water, such as Escherichia coli, Bacillus subtilis, Staphylococcus aureus, and Pseudomonas aeruginosa, using a specific polymer compound. It is related to methods for removing bacteria. Conventional Technology For environmental pollution prevention and health reasons, wastewater from pools, bathhouses, and hospitals must be sterilized before being discharged, and when river water, groundwater, well water, etc. Sterilization is required. Up until now, methods have been used to disinfect such water by adding disinfectants such as chlorine gas, chlorate, and ozone, but these methods leave residual chemicals, which can lead to secondary contamination. It has the disadvantage of causing On the other hand, as a method for purifying water, there is a known method of using an appropriate scavenger to capture and remove microorganisms in the water. can be avoided. Strongly basic anion exchange resins are known as scavengers for these microorganisms, but their scavenging performance cannot be said to be sufficient. In addition, divinylbenzene-crosslinked poly-N-benzyl-4-vinylpyridinium bromide also has the effect of capturing microorganisms in water, but its scavenging performance is low [“Kobunshi Processing”, No. 34
vol., p. 583 (1985)]. Problems to be Solved by the Invention The purpose of the present invention is to provide a treatment method that can efficiently remove bacteria in water, has no residual toxicity, and has simple post-treatment. Means for Solving the Problems As a result of various studies on methods for removing bacteria in water, the inventor of the present invention has discovered that certain polymer compounds exhibit strong bactericidal and sterilizing effects against bacteria in water. The present invention was developed based on this finding. That is, the present invention provides water containing bacteria with (a) styrene units, (b) general formula [R in the formula is the general formula -O-( CH2CH2O )nH...() (where n is an integer from 1 to 45) -O-(CH2CH2O ) n'R '...() ( (where R' is a long-chain alkyl group, n' is an integer from 1 to 10) -NH-(CH 2 CH 2 NH) nH ... () (However, n has the same meaning as above) or (where m is an integer of 8 to 16, and n has the same meaning as above) A cross-linked polystyrene-based polymer compound consisting of a structural unit represented by The present invention provides a method for removing bacteria characterized by a treatment. The cross-linked polystyrene polymer compound composed of polystyrene units, structural units of the general formula (), and divinylbenzene units used in the method of the present invention is produced by chloromethylating divinylbenzene-crosslinked polystyrene, and then reacting polyethylene glycolate or polyethyleneimine with this. It can be manufactured by In addition, the polymer compound having a quaternized residue of the general formula () is a polymer compound having a quaternized residue of the general formula ().
It can be obtained by quaternizing a polymer compound having a residue of with an alkyl iodide. At this time, chloromethylated divinylbenzene-crosslinked polystyrene (hereinafter referred to as
CMPS (abbreviated as CMPS) can be easily obtained as a commercial product, and can also be easily produced by introducing divinylbenzene-linked chloromethyl groups in the required ratio by a known method. In order to introduce polyethylene glycol or its monoalkyl ether into this CMPS, dry metallic sodium of polyethylene glycol or its monoalkyl ether is added, and the sodium is completely reacted by stirring at about 100°C for 1 to 3 days. , sodium polyethylene glycolate or its monoalkyl ether is produced, dioxane is added thereto, heated and stirred to dissolve it, then CMPS is added thereto and heated to 95-97°C.
Stir and react for 1 to 3 days. At this time, benzene can be used as a solvent, but the introduction rate of polyethylene glycol or its monoalkyl ether can be increased by using dioxane. In addition, to introduce CMPS ethylene diamine, polyethylene polyamine or polyethylene imine, put CMPS in dimethylformamide, add ethylene diamine, polyethylene amine or polyethylene imine to it, and heat it at about 100°C for 50 minutes.
Stir for ~10 days. In this way, CMPS containing ethylenediamine, polyethyleneamine, or polyethyleneimine can be obtained, but when this is reacted with a stoichiometric amount of alkyl iodide, a polymer compound with quaternized residues can be obtained. can. In the method of the present invention, the polymer compound thus obtained is added to bacteria-containing water and stirred to bring the polymer compound into sufficient contact with the bacteria. When treated in this way, the number of viable bacteria in the water gradually decreases, but at the initial stage of contact (2 to 3 hours), there is an almost direct relationship between the logarithm of the number of viable bacteria over time and the contact time. Therefore, the effectiveness of each polymer compound in reducing the number of viable bacteria can be compared by calculating the coefficient of decrease in the number of viable bacteria (D) from the following formula: D = (V/Wt) log (N p /N t ). Can be done.
Here, V is the volume of the contact liquid (ml), W is the mass of the polymer (g), N p is the number of primary bacteria, and N t is the number of viable bacteria after t time (hr). When contacted with a polymer compound containing a residue of general formula () or (), contact 4
The absorbance at 600 nm (od 660 ) of the contact solution after a period of time was lower than that before contact, indicating that these polymer compounds captured bacteria in the water.
In the case of contact with a polymer compound containing a residue of general formula () or (), the od 660 after 4 hours of contact was slightly higher than before contact. Therefore, this polymer compound does not trap bacteria. However, since this polymer compound reduced the number of viable bacteria upon contact, it can be said to have antibacterial properties. In addition, when using a column method, by filling the column with the polymer compound and passing bacteria-containing water through one port, sterilized or sterilized water can be obtained from the other port. can. The scavenging ability of the saturated polymer compound that traps bacteria is regenerated by immersing it in a 1N sodium hydroxide solution, or by passing the same solution through a column packed with the same polymer compound. Can be done. EXAMPLES Next, the present invention will be explained in more detail using reference examples and examples. Reference example 1 Polyethylene glycol with a molecular weight of approximately 600 (hereinafter

I stirred it for 30 hours. After the reaction was completed, an appropriate amount of boiled water was added and stirred, and the reaction product was filtered and washed with 200 ml of boiled water.
Furthermore, 50 ml of water was added to this, and stirring was continued for 24 hours at approximately 95°C. After the reaction product was filtered off, the heating, stirring and filtration operations were repeated five times. This product was extracted with ethyl alcohol for 72 hours and then dried under reduced pressure at 80°C. In this way, CMPS with benzyl groups substituted with PEG600 was obtained. The yield and elemental analysis values of this product are shown in Table 1. Table 1 also shows the reaction conditions and results when lauryl ether (hereinafter abbreviated as PEGLE) was reacted in the same manner instead of PEG600. Reference Example 2 The same 3.00 g of CMPS as in Reference Example 1 and 2.37 g (0.0394 mol) of ethylenediamine were stirred in 20 ml of dimethylformamide at about 98°C for 192 hours.

After the reaction was completed, hot water was added and the reaction product was filtered and washed with hot water, 1N hydrochloric acid, 1N aqueous sodium hydroxide solution, and water. Next, 50 ml of water was added to this reaction product, the mixture was stirred at about 95°C for 24 hours and then filtered, which was repeated 7 times, extracted with ethyl alcohol for 72 hours, and dried under reduced pressure at 80°C. In this way, ethylenediamine substitution
CMPS (hereinafter abbreviated as CMPS-ED) was obtained. The yield and elemental analysis values of this product are shown in Table 1. Similarly, for traethylenepentamine substitution,
CMPS (hereinafter abbreviated as CMPS-TEP) and polyethyleneimine-substituted CMPS (hereinafter CMPS-PEI)
) was manufactured. Table 1 shows the reaction conditions and results at this time. In addition, PEI300 and PEI1200 each have a molecular weight of approximately
It shows a PEI of 300 and a PEI of molecular weight 1200. Reference Example 3 Add 5.70 g of octane iodide to a mixture of 3.00 g of CMPS-ED obtained in Reference Example 2 and 15 ml of dioxane.
(0.0237 mol) was added and stirred at approximately 95°C for 96 hours. After the reaction product was filtered and washed with methyl alcohol and boiling water, 50 ml of water was added and the mixture was heated at about 95°C for 24 hours.
The operation of stirring and filtering was repeated 7 times. The mixture was then extracted with ethyl alcohol for 72 hours and dried under reduced pressure at 80°C. In this way, CMPS-ED quaternized with octane iodide (hereinafter abbreviated as CMPS-ED-IO) could be obtained. The yield and elemental analysis values of this product are shown in Table 1. Similarly, CMPS-TEP was reacted with iodized dodecane, and quaternized with iodized dodecane.
CMPS-TEP (hereinafter abbreviated as CMPS-TEP-IDD) was obtained. The reaction conditions and results at this time are shown in Table 1.
