A kind of preparation method of water purification material and its application

Abstract

The invention discloses a method for preparing a water purification material. The water purification material is prepared by smearing a special glaze on the ceramic surface, immersing it in a plant fermentation liquid with a high carbon-nitrogen ratio after high temperature treatment. After putting it into the water body, the high carbon-nitrogen ratio fermentation broth is continuously released around the ceramics with the water flow, adjusting the carbon-nitrogen ratio of the water body near the ceramics, and promoting the high-quality algae phase and bacteria phase in the ceramics and the water body, as well as high-quality lactic acid bacteria in the ceramics. The homogeneous reproduction and proportion of environmental protection strains, etc., promote the restoration and stability of the water ecosystem.

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 urban segments that flow through human habitation and are disturbed by urbanization and human activities. With the rapid development of urbanization and industrialization, the river, which is the blood of the city, is recklessly used as the sewage channel of the city and suffers increasingly serious pollution. Rivers have a natural self-purification function. In the natural environment, various pollutants are removed through microbial oxidation, physicochemical action, and plant absorption. However, when the total amount of pollutants received by urban rivers far exceeds the environmental capacity of the river itself, the pollutant-absorbing capacity o...

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
