Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a method for treating high turbidity water' and particularly to a biological coagulant and a process for treating high turbidity water. [Prior Art] Traditionally, the clean water treatment process is mostly a coagulation and sedimentation treatment program. The design standard of the coagulation sedimentation unit is within two thousand degrees of raw water turbidity, and can be 100% water. If the turbidity reaches five thousand degrees. , it is necessary to strengthen the pharmacy, the water output is only about 85 percent; the turbidity is 5,000 to 10,000 degrees, the water output drops to 80%, and about 10,000 degrees, only 50% of the water, only 10% of the 10,000 or more. And when the water output is only 75% to 85%, the district water supply is required, which has a considerable impact on people's livelihood or industry. At present, chemical coagulants commonly used in water purification include aluminum sulfate (A12(S04)3), ferric chloride (FeCl3), polyaluminized aluminum (PAC1), polyacrylamide (PAM), polychlorinated hexahydrate. Poly(diallyldimethyl ammonium chloride) > poly (DADMAC) and epi-DMA polyamines (epichlorohydrin dimethylamine polymer), for example, when treated with PAC1, Add liquid test to raise the pH to about 8~9, then add PAC1 to carry out the coagulation action, so as to control the pH neutral coagulation range during coagulation, the cost is high and the water conductivity and total decomposed solidity after treatment The value of the material (TDS) is higher, and the charge density of the PAC1 (10%) coagulant is 1,375,000 meq/g, which is easy to suspend solids due to high turbidity. The dosage of 0296-A21698TWF(N2):358 :kai 6 1322135 increase, so that it is difficult to achieve electrical neutrality, resulting in anti-turbidity of water quality. When the turbidity is greater than 2000 NTU, it can not be efficient coagulation and rapid sedimentation, resulting in water shortage. In addition, when treated with PAC1, It is easy to cause the problem that the treated water contains residual aluminum carcinogenicity. The object of the present invention is to provide a biological coagulant and a method for treating high turbidity water, wherein the turbidity of the treated water is reduced to below 5 NTU, the amount of the residue is below 0.1 mg/L, and the supernatant does not occur. In order to achieve the above object, the present invention provides a biological coagulant suitable for treating high turbidity water, wherein the conductivity of the biological coagulant is between 2.13 mS/cm and 16.17 mS/cm. And the charge density is between 120 meq/g and 3055 meq/g. To achieve the above object, the present invention further provides a method for treating high turbidity water, comprising adding a biological coagulant to high turbidity water, and undergoing a coagulation and a sedimentation step, wherein the biocoagulant has a conductivity between 2.13 mS/cm and 16.17 mS/cm, and a charge density between 120 meq/g and 3055 meq/g, further comprising adding chemical condensation after the sedimentation step The above and other objects, features, and advantages of the present invention will become more apparent and understood.

Referring to Figure 1, the single-stage treatment system has a conductivity of between 2.13 mS/cm and 16.17 mS/cm, and the charge density is The biological coagulant having a pH between 1 and 5.0 and a concentration of 0.1 to 5% is added to the high turbidity water between 120 meq/g and 3055 meq/g, and the biological coagulant is added in an amount of 5 ppm to 5000 ppm. Preferably, between 500 ppm and 3000 ppm, the steps of coagulation (fast mixing, slow mixing) and sedimentation are carried out in sequence. Referring to Fig. 2, wherein the slow mixing step can use the multi-tank series operation mode, the plurality of slow mixing tanks 201 and the plurality of agitators 203 are used to increase the effect of removing turbidity. In a preferred embodiment, the biocoagulant has a conductivity of about 2.37 mS/cm, a charge density of about 1015.6 meq/g, a pH of about 4, and a concentration of about 1%. The coagulation step includes fast mixing and slow mixing. The speed of the fast mixing is between 180 and 200 rpm, the time is between 20 seconds and 60 seconds, and the speed gradient (G) is between 200 s_1 and 400 s-1. The mixing speed is between 55 and 75 rpm, the time is between 3 and 30 minutes, the speed gradient (G) is between 20 s·1 and 75 s·1, and the Gt value is between 2xl04 and 2xl05. The settling time is from 1 to 120 minutes, preferably 10 minutes. The biocoagulant of the present invention has a low influence on conductivity, and the obtained glue has no aluminum residue and turbidity removal rate of more than 90%, and there is no overdose problem of anti-turbidity. Referring to Fig. 3, the two-stage treatment includes the first stage of pretreatment and the 0296-A21698TWF(N2):358:kai 8 1322135 two-stage chemical mixing treatment, in which the biological coagulant of the present invention is added to the first stage. In turbidity water, after the first coagulation and the first settling step, the turbidity can generally be reduced from 27072 NTU to 2000 NTU. The biological coagulant is added in an amount of from 10 ppm to 200 ppm, preferably from 30 ppm to 40 ppm. The first coagulation step includes fast mixing and slow mixing, wherein the fast mixing speed is between 18 〇 and 200 rpm, the time is between 20 seconds and 60 seconds, and the speed gradient (G) is between 200 s-1 and 400. The speed of slow mixing is between 55 and 75 rpm, the time is between 3 and 30 minutes, and the speed gradient (G) is between 40 s·1 and 70 s·1. The Gt value is 1〇4-1〇. 5. The settling time can be from 1 to 12 minutes, preferably about 10 minutes. The slow mixing step includes a multi-slot series operation mode as shown in FIG. Next, a chemical coagulant is added in the second stage, followed by a second coagulation and a second settling to reduce the turbidity from 2000 NTU to less than 5 NTU. The chemical coagulant may be Al2(S〇4)3, FeCl3, polypropylene decylamine, polygas hexadienyldidecylamine, gas sulfhydryl monooxydicyclodecylamine polymer or polychlorinated ' Among them, it is better to use gasification.

The parameters of the second settling can be the same as the settling of the first stage. After two-stage treatment, the containing quantity test can be lower than mg/L, which means that the two-stage treatment can effectively reduce the amount of additive of polynitrile, so the reduction of 0296-A21698TWF(N2):358; kai 9 1322135 residual aluminum is greatly reduced. The build is possible. EXAMPLES Example 1: Single-stage treatment method A solution of 1%, ρΗ4, a conductivity of 2.37 ms/cm, and a charge density of 1,016 meq/g of chitosan coagulant was added to 1000 ml of high turbidity water, raw water. The turbidity is 27072 NTU, and the raw water mixer is Jar Test type, and the parameters are shown in Table 1. After the addition of the chitosan coagulant, 190 rpm, 30 seconds of rapid mixing, 65 rpm, 558 seconds of slow mixing, and 600 seconds of sedimentation were used to remove suspended particles in the raw water. In addition, high turbidity water of polychlorinated rice was added as a control group. It can be seen from Fig. 4 that the sedimentation rate of chitosan coagulant is about 5-10 times faster than that of polyaluminium chloride. It can be seen from Fig. 5a-5d that the chitosan coagulant does not affect the pH and conductivity of the raw water. And the turbidity removal rate can reach more than 90%, but the polyaluminum chloride will lead to an increase in the conductivity of the raw water (5-10 times higher than the coagulant of the present invention), a decrease in pH, a high alkalinity, and a supernatant will occur. The phenomenon of liquid turbidity. Referring to Table 2, the turbidity can be reduced to 6 NTU at a concentration of 600 ppm, and the turbidity can be reduced to 5 NTU at a dose of 1500 ppm.
