Problems solved by technology

However, the characteristics of low carbon sources and low sludge activity in natural water bodies such as rivers and lakes are unfavorable conditions for microbial film formation, which greatly reduces the application effect of filler biofilm method in the process of natural water purification.
At present, there are few biofilm fillers specially developed for natural water bodies and their characteristics, and some new materials are not widely used because of their high prices. Therefore, a biofilm that can overcome the characteristics of low carbon sources and low sludge activity in natural water bodies Membrane filler is a key demand in the current natural water treatment process

Embodiment 1

[0036] (1) Soak the ordinary biofiller of the PET material in a sodium hydroxide solution of 90 ° C, soaking time is 45 minutes;

[0037] (2) The filler ends the end of the (1) step is soaked in 1% polyvinyl alcohol (alcohol solution 99%, the degree of polymerization 1700) and 0.001% ethylenedialdehyde solution, soaking for 5 minutes;

[0038] (3) The filler was dried at 120 ° C for 20 minutes to obtain a modified biofiller.

[0039] Note: The method of the present invention relates to a polyester fiber surface treatment technique and a polyvinyl alcohol polycondensation technique. In the present invention, the surface treatment technique of the present invention produces uneven elimination of unevenness (polyester) fiber surface, increasing the adhesion of the surface of the filler. Ability; polyvinyl alcohol polycondensation techniques can condense the long chain PVA portion to form a varicon having strong mechanical properties, but it has water resistance, and thus the core of ...

Embodiment 2

[0044] (1) Soak the ordinary biofiller of the PET material in a hydroxide solution of 10 g / L of 75 ° C, soaking time is 30 minutes;

[0045] (2) Soak the filler in 5% polyvinyl alcohol (99%, polymerization 1700) and 0.002% ethylenedical solution, soaking for 3 minutes;

[0046] (3) The filler was then dried at 105 ° C for 15 minutes to obtain a modified biofiller.

[0047] Description of Example 1.

[0048] The modified biofilm with the control group (unremnive treatment) was placed in a certain river channel (the same, specifically in the middle of the zone), recording the hanging film, the record weight is shown in Table 2 below:

Abstract

The invention relates to a biological membrane filler modification method suitable for natural water and components. The biological membrane filler modification component suitable for the natural water body comprises a biological membrane filler made of a polyester fiber material, a first modification liquid and a second modification liquid, and the biological membrane filler suitable for microbiological method treatment of the natural water bodies such as rivers and lakes is obtained through proper combination treatment of the first modification liquid and the second modification liquid. The raw materials are easy to obtain and low in price, the method is a modified biological membrane filler technology with high operability, treatment is carried out on the basis of a common sewage biological membrane filler, the problems that the filler is difficult to form a membrane, poor in adhesive force and easy to fall off under the characteristic conditions of low carbon source, low sludge activity and the like of natural water are solved, and the sewage treatment efficiency is improved. And a new compatible carrier and thought are provided for microbiological treatment of natural water.

Description

Technical field [0001] The present invention belongs to the field of modified biofilms, which relates to microbial treatment, and more particularly to biofilm modification methods and components suitable for use in natural water. Background technique [0002] The biofilm in the sewage treatment plant is also gradually developed in natural water governance such as rivers. However, the low-carbon source of natural water such as river, lake, and low sludge activity is the adverse conditions of microbial hanging film, so that the application effect of the filler biofilm method during the purification of natural water purification. At present, there are few biofilts developed for natural water and their characteristics, and some new materials are not widely used because of high prices, so there is a biological organism that overcomes low-carbon source and low sludge activity of natural water. The membrane filler is a key demand in the current natural water governance process. Inventi...
