Description
Technical Field
The invention relates to the technical field of sewage treatment, in particular to a high-efficiency microbial preparation for repairing black and odorous water and bottom mud and a preparation method thereof.
Background
The river is used as a life source of a city and plays an important role in the urban development process, and the water quality condition of the urban river directly influences the living environment and quality of people. However, with the rapid development of economy, rivers in China are seriously polluted, wherein the pollution problem of black and odorous rivers is particularly prominent, particularly, the black and odorous water body is formed, and a large amount of pollutants are gathered in bottom mud to seriously threaten the water body ecosystem and the human living environment. The black and odorous phenomenon has occurred both in the developed countries and in the developing countries at home and abroad. Developed countries also have serious black and odorous pollution in the process of economic rapid development, for example, thames rivers in the United kingdom suffer seriously and are recovered to be normal through long-term treatment, and the method becomes one of successful cases of riverway restoration. The method also commonly exists in urban water environment problems in China and is in a development trend. The black and odorous phenomenon of the river channel will aggravate the shortage of water resources, resulting in the continuous deterioration of the ecosystem. Meanwhile, drinking water and agricultural water in China are seriously polluted, and the human health and the agricultural production are directly influenced. The quality of industrial products is reduced due to the problem of water quality, the industrial production with higher water quality requirement is limited, the industrial yield is continuously reduced due to the lack of water quantity, the life quality of urban residents is seriously influenced by urban black and odorous rivers, and the urban development is restricted.
The black and odorous cause of the river is complex, the treatment is difficult, and the treatment modes are various, but the treatment modes can be roughly divided into three types, namely a physical method, a chemical method and a biological-ecological method, wherein the physical repair technology mainly comprises dredging and covering, and the dredging refers to removing the maximum amount of polluted bottom mud from the river and transferring the polluted bottom mud to other places. But generally at a high cost and he simply moves the pollution problem to another location and further management is required. Dredging projects may miss contaminated areas, residual contaminated sediment may mix with underlying or surrounding sediment, and suspended sediment may migrate downstream and affect downstream ecosystems. Dredging is the most invasive technique and leads to alteration or destruction of the benthic organism community, and in addition, the presence of boulders and debris may limit its effectiveness and hinder the removal of low pollutants. Dredging's effectiveness in sediment remediation has been questioned in recent years and has been limited to covering the contaminated sediment surface with clean material to isolate the sediment from the overlying water phase and prevent or control the migration of contaminants in the sediment to the overlying water . The covering is mainly to repair the black and odorous bottom mud through hydraulic retardation, adsorption and degradation, and the used materials are soil, gravel, sand, ore, geonet, geomembrane and the like. But the coverage requires long-term monitoring and has a certain risk because the contaminants remain in place. Short-term risks result from the contaminated substrate sludge mixing or suspending with the material during the placement of the covering material, and in addition, difficulties in the implementation of covering techniques in deeper waters, in wavy regions, in ship traffic or in large target areas; the long-term risks result from erosion of the overburden and diffusion of contaminants through the overburden, as well as from destruction of groundwater seepage patterns and flow around the overburden, and chemical remediation techniques primarily control contaminants in the substrate sludge by adding chemicals such as chelating agents, salts, and the like. The method mainly comprises the modes of chemical precipitation, cementation, oxidant injection and the like. Nowadays, commonly used oxidants include salts of high-manganese acids, Fenton's reagent, hydrogen peroxide, ozone, persulfate, calcium nitrate, and the like. But the effect has a certain time period. The salts commonly used in the chemical method are iron salt, aluminum salt, calcium salt and the like. Chemical methods may present some potential threats to water remediation and therefore are generally only emergency measures, and the mechanisms of phytoremediation include biophysical and biochemical processes such as adsorption, transport and transport, and plant enzymatic conversion and mineralization. Phytoremediation often uses super-accumulating species for remediation of heavy metal contaminated substrate sludge, but for remediation of organic contaminated substrate sludge super-accumulation is not utilized, but rather the contaminants may be fully mineralized or converted to lower or non-toxic components. The main disadvantage of phytoremediation is that the detoxification process of organic pollutants is usually very long, if the organic pollutants are not completely decomposed, toxic compounds may be accumulated in plant tissues and released into the environment or enter the food chain, and microbial preparations are a very active research direction in the field of bioaugmentation technology, have wide application in various fields such as agriculture, industry, medicine, food and the like, and are in the exploration stage when applied to the field of environmental protection. Therefore, the technical personnel in the field provide a high-efficiency microbial preparation for repairing black and odorous water and bottom mud and a preparation method thereof, so as to solve the problems in the background technology.
