In-situ water body remediation material adopting natural minerals

Abstract

The invention provides an in-situ water body remediation material adopting natural minerals. The in-situ water body remediation material adopting natural minerals is prepared from raw materials as follows: volcanic ash, dolomite, clinoptilolite, rock-forming minerals and clay minerals with high ion substitution capacity. The prepared in-situ water body remediation material adopting the natural minerals can be completely applied to pollution treatment of rivers, lakes and other water bodies and can decompose pollutants in various water bodies and notably reduce the turbidity. Green algae, red tide and eutrophication of the water bodies are effectively prevented, the water quality and the habitat environment of aquatic organisms are improved, the biodiversity is kept to the greatest extent,and the in-situ water body remediation material has the characteristics of being energy-saving, environmentally friendly, remarkable in effects, free from secondary pollution, capable of taking effectrapidly, wide in application range, convenient to use and free from restriction by environmental conditions.

Description

Technical field [0001] The invention relates to a water body repairing material, in particular to a natural mineral in-situ water body repairing material for removing water pollution of rivers, lakes and rivers. Background technique [0002] With the great development of the industrial revolution, river pollution once reached a very serious level. Limited to the development of technology and economic level in our country, the research on water environmental pollution started relatively late. Research on urban runoff pollution in Beijing began in the early 1980s. Subsequently, Shanghai, Nanjing, Suzhou and other medium and large cities have gradually started relevant research work. In terms of governance, only simple methods are used, and the results are often only short-term, and not ideal in the long-term. With the development of modern ecology, people realize that the pollution control of rivers is not just a simple change of water quality and removal of pollutants. It's as si...

AI Technical Summary

Problems solved by technology

However, dredging easily destroys the sediment ecosystem and reduces the self-purification ability of the water body, and requires the cooperation of multiple departments, and the cost of transportation and landfill is huge; ecological water diversion can quickly improve water quality and water dynamics conditions, and increase the diffusion, evolution and output of pollutants in water

However, its essence is the transfer of pollutants rather than effective emission reduction, and has not fundamentally solved the problem; chemical methods are simple to operate and can quickly control and alleviate target pollutants in water bodies

However, the bioaccumulation and biomagnification of chemical agents have a negative impact on water ecology, which will cause secondary pollution and are very easy to rebound; biological bacteria agents have strong adaptability and impact resistance, can increase water body biodiversity, enhance self-purification ability, and improve water body water quality

However, it is greatly affected by the external environment, slow to take effect, easy to lose, and has the risk of alien species invasion; plant purification can not only absorb and degrade nutrients in the water through the huge root system, enrich toxic and harmful substances, but also enhance the landscape effect

However, it has high requirements on light and dissolved oxygen, and often takes effect slowly. Later management is greatly restricted by environmental conditions.
