Problems solved by technology

However, when the total amount of pollutants received by urban rivers far exceeds the environmental capacity of the river itself, the pollution-holding capacity of the river plummets, serious eutrophication occurs, and the original ecological balance of the river is destroyed, and some rivers are completely reduced. for the smelly ditch
[0003] Treatment of urban river pollution is a complex systematic project. Currently, treatment technologies mainly include three types of methods: physical, chemical and biological-ecological methods: physical methods mainly include artificial oxygenation, mechanical algae removal and sediment dredging, etc., but these methods are often palliative It does not cure the root cause, the pollutants are only transferred but not eliminated; the chemical method mainly uses a large amount of chemical agents into the river, such as adding chemical agents to kill algae, adding iron salts, etc. to promote the precipitation of phosphorus, etc., but these methods are often due to chemical agents. pollution to the environment due to high investment; bio-ecological methods mainly include methods such as aquatic plants, biofilms, floating island technology, specialization of rivers, or construction of clean water lakes. Although these methods have good treatment effects, low energy consumption, and low operating costs and other advantages, but the amount of early stage engineering is relatively large and the cost is relatively high

Embodiment 3

[0052] Such as figure 1 As shown, the water body purification material of Example 1 is set in the urban river water body. After the urban river water body passes through 2 water body partitions, it is blocked and enters the water body purification area 3 through the branch road. The water flows through the gravel layer 32 to filter out the floating Then enter the water purification material layer 31 through the isolation net 33. The high carbon-nitrogen ratio fermentation broth in the water purification material layer is continuously released with the water flow to adjust the carbon-nitrogen ratio of the water near the ceramics, and promote the high-quality algae, bacteria and bacteria in the water. The homogeneous reproduction and proportion of high-quality live lactic acid bacteria and environmentally friendly strains in ceramics promote the restoration and stability of the water ecosystem.

[0053] The water treatment effect is shown in Table 1:

Abstract

The invention discloses a preparation method of a water purification material. A special glaze is smeared on the surface of ceramic, high-temperature treatment is performed, and the treated ceramic issoaked in a plant fermentation solution with high carbon-nitrogen ratio to obtain the water purification material. After the water purification material is put into a water body, the high-carbon-nitrogen-ratio fermentation liquor is continuously released around the ceramic along with water flow, the carbon-nitrogen ratio of the water body near the ceramic is adjusted, homogeneous propagation andproportion of high-quality algal phases and bacterial phases in the ceramic and in the water body, and high-quality viable lactic acid bacteria, environment-friendly strains and the like in the ceramic are promoted, and recovery and stability of a water body ecosystem are promoted.

Description

Technical field [0001] The invention relates to a preparation method and application of a water purification material, in particular to a preparation method and application of an urban river water purification material, and belongs to the field of river purification. Background technique [0002] Urban rivers usually refer to sections of cities where humans live and are disturbed by urbanization and human activities. With the rapid development of urbanization and industrialization, rivers, which are the blood of the city, are used as the city's sewage channels and are suffering from increasingly serious pollution. The river has a natural self-purification function. In the natural environment, various pollutants can be removed through microbial oxidation, physical and chemical effects, and plant absorption. However, when the total amount of pollutants received by urban rivers far exceeds the environmental capacity of the river itself, the river’s capacity for receiving pollution ...
