Ecological dam protecting material capable of absorbing such pollutions as nitrogen and phosphorus in water and preparation method of material

Abstract

The invention discloses an ecological dam protecting material capable of absorbing such pollutions as nitrogen and phosphorus in water and a preparation method of the material. The material, adhering to the core of water supply plant sludge, natural zeolite, ordinary Portland cement and plant foaming agent, modifies the water supply plant sludge and the zeolite to absorb nitrogen and phosphorus elements as well as organic substance in water, thus constructing an ecological system growth matrix environment, so as to realize self-purification function of the water; the ordinary Portland cement and the plant foaming agent, as accessories, serve as controlling honeycomb structure, water permeability, gas permeability and mechanical performance of the material, thus constructing a 'nutrient element absorption and immobilization-biological reproduction-water purification' ecological structure. The material has the advantages of being simple in proportion, low in investment, environment-friendly and efficient, and has advantages on honeycomb structure, water permeability, gas permeability, mechanical performance and the like. The material disclosed by the invention not only guarantees communication and slope protection functions among air, water and soil of river bank slope, but also can be used for improving the surrounding atmospheric environment, thus generating an excellent landscape effect.

Description

technical field [0001] The invention relates to an ecological embankment material capable of absorbing pollutants such as nitrogen and phosphorus in water bodies and a preparation method thereof. The technical field belongs to the fields of river regulation, ecological concrete and environmental protection materials. [0002] The material of the present invention is made of specially graded raw materials and cementing materials. While its mechanical properties meet the requirements of engineering use, it has a honeycomb structure, porous and continuous characteristics, and good water permeability and air permeability. Plants and microorganisms can Growing in it can not only ensure the safety and stability of the river bank slope, but also provide favorable conditions for the ecological restoration of the river bank slope, thereby protecting the ecological environment of the water body and improving the self-purification ability of the water body.

AI Technical Summary

Problems solved by technology

However, there are few practical applications in foreign countries. The main reason is that the solid matter in the sewage is deposited on the concrete, which will quickly block the pores of the macroporous concrete, making it lose the water purification function; and the water purification effect of ordinary macroporous concrete (especially turbidity) degree, etc.) is not ideal, and concrete loses a lot of calcium ions in flowing water

The cement hydration product is decomposed and the strength is reduced until it is destroyed, so the durability of concrete is not enough
