Problems solved by technology

[0003] In the treatment of urban rivers in my country, the treatment methods are mostly traditional algicides, algae sinking agents, flocculants, and often only pay attention to surface engineering such as dredging, dredging, revetment, greening, and sewage interception, which are generally used in the country. Neglecting the bioremediation of sediment and water bodie...

Embodiment Construction

[0020] In the urban inland rivers that need to be treated, according to the concentration of water pollutants and the length and width of the inland rivers to be treated, different quantities of biological purification materials are used to spray them in a certain proportion into the river or place them in a certain number of ecological beds.

[0021] Such as figure 1 In the process, the biological purification material 2 is placed in the ecological bed 1. After the ecological bed is placed on the bottom of the river, the biological purification material 2 in the ecological bed 1 begins to reproduce in large numbers, and the organic matter in the river bottom mud is used as the nutrient component, and the macromolecular organic matter , Such as protein, starch, cellulose and nucleic acid and other decomposition processes are carried out outside the cell, catalyzed by the corresponding enzymes. However, the decomposition process of small molecular organic substances, such as mo...

Abstract

The invention provides a biological purification material and device, which can increase rapidly the dissolved-oxygen content with saturation radio more than 90% for long time in polluted water of city, boost inorganic process of oxygen-consumption deposition in riverbed bottom to eliminate pollution locally, accommodate ecological balance, avoid eutrophication of nitrogen and phosphor in water, and remove harmful toxic material, such as nitrite and sulfide. Wherein, the main purpose lains on improving removal rate of COD and BOD to recover self-purification and detoxification function of water body.

Description

Technical field [0001] The invention relates to a sewage purification material and a device, especially having a good effect on urban inland river sewage treatment. Background technique [0002] At present, with the development of my country's economy and the increase of urban population, a large amount of industrial wastewater, domestic sewage and surface runoff without effective treatment are discharged into the river, causing the river water to be black and smelly. Black and smelly rivers are a common phenomenon in urban river networks in my country, which seriously affect residents' lives, city image and urban investment environment. Black and smelly inland rivers have become an important part of urban water environment governance. [0003] In the treatment of urban rivers in my country, the treatment methods are mostly traditional algicides, algae sinking agents, flocculants, and often only pay attention to surface engineering such as dredging, dredging, revetment, gree...
