Description
Technical Field
The invention belongs to the technical field of sewage treatment, and particularly relates to a material for treating river and lake water pollution environment, a preparation method and application thereof.
Background
The direct cause of the problem in water environment is that pollutants are gathered, nutrient substances such as nitrogen, phosphorus and the like required by organisms enter slowly flowing water bodies such as lakes, rivers, lakes and gulfs in a large amount, so that the water bodies of the rivers, the lakes are eutrophicated, most of the rivers, the lakes are weak in pollution resistance and load resistance due to insufficient self-cleaning capability of the water bodies, the problem of water pollution is further aggravated, and black and stink are caused in ditches of urban rivers and rural pits, so that the problems of eliminating black and stink, improving the appearance of the water bodies and creating pleasant water environment are the water environment problem which needs to be solved urgently at present.
The most economical and applicable method for carrying out denitrification and dephosphorization treatment on the pollution with N, P content exceeding the containing capacity of the receiving water body is a biological method, organic matters in sewage are decomposed through the metabolism of microorganisms in the water body, the purposes of denitrification and dephosphorization and sewage purification are achieved, organic nitrogen is converted into ammonia nitrogen through ammoniation, ammonia nitrogen is converted into nitrate nitrogen through aerobic nitrification, nitrate nitrogen is converted into nitrogen through anaerobic denitrification, and finally the nitrogen is discharged from the water body, so that the effect of reducing the nitrogen content of the water body is achieved. In the microbial denitrification process, a large amount of organic carbon source is needed to provide energy and nutrient substances for the microbial denitrification process, and in the biological denitrification process, the carbon source plays a decisive role in denitrification capacity and efficiency in the denitrification process, so that the sewage needs to be additionally provided with the carbon source to ensure the normal growth and propagation requirements of microorganisms in water.
At present, most of fillers used as pollution water body treatment links are made of materials such as plastics, glass fiber reinforced plastics, nylon, fibers, terylene, acrylic fibers and the like, and the fillers have the advantages of large specific surface area, small volume, easy assembly, convenient transportation and the like, but the fillers are low in strength, not corrosion-resistant and lack of stable physical and chemical properties. The patent publication No. CN103068356B discloses a modified carbon fiber surface modification method, acetone, nitric acid and activated gas are used for modification, and the obtained modified carbon fiber can provide a carrier for growth and propagation of microorganisms and algae in water, but the combined application of the carbon fiber is not reported. The prior art publication No. CN112551702A discloses a microbial wax for water treatment and a preparation method thereof, wherein the microbial wax and a polyvinyl alcohol fiber net are included, the microbial wax can release a carbon source, which is beneficial to the growth and propagation of microorganisms, the polyvinyl alcohol fiber net enables paenibacillus growing and propagating on the pore wall to be in contact with water, and improves the water treatment efficiency, however, in the prior art, the microorganisms have no effective carrier, because the microorganisms attached to the carrier can prevent the loss and attenuation of the microorganisms, and the microorganisms are propagated in the sewage in geometric poles, so that the impact resistance is strong, and the treatment efficiency is greatly improved. So that the water treatment efficiency of the prior art is lower.
Through the above analysis, the problems and defects existing in the prior art are as follows: in the water environment pollution treatment of the prior art, the carrier lacking the pollution water body treatment link and the water body lacking the carbon source make the efficiency of the pollution water body treatment link lower; the prior art sewage treatment material has complex preparation process, inconvenience, high economic cost and poor practicability, and is suitable for ecological environment treatment of polluted water bodies.
