Problems solved by technology

At present, the materials used to construct biological floating islands in engineering examples are mainly organic polymer materials. The carrier surface area of ​​this material is small, which is not conducive to microbial film formation. At the same time, it is afraid that strong winds and waves are easy to damage, and some materials are not easy to degrade. Easy to form "white pollution"

Embodiment 1

[0014] Embodiment 1: A kind of pumice material manufacturing method that is used for artificial floating island, comprises the following several steps: Step A): filter the glass slag, artificially pick out the large particle material in the glass slag, filter through the filter screen Remove tiny impurities and dust, and then grind the glass slag so that the glass slag becomes glass powder with a fineness of at least 2000 mesh. The source of glass shards can be old glass from old glass windows, or other waste glass products. Step B): Obtain sodium nitrate powder with a purity of more than 90% and a fineness of at least 500 mesh. Step C): Mix glass powder and sodium nitrate powder to form a batch, weigh the sodium nitrate powder according to the proportion, add it to the glass powder that has been weighed according to the proportion, and put them together in a mixer for stirring and mixing. In terms of mass percentage, the batch contains 95%-97% glass powder and 3%-5% sodium n...

Abstract

The invention discloses a making method of a pumice material used for an artificial floating island and relates to pumice materials. The main making technology includes the steps that glass powder and sodium nitrate are mixed evenly, a mixed batch is prepared and then put into a mold to be spread flat, both the mixed batch and the mold are put into a muffle furnace, and then the environmentally-friendly pumice is prepared after constant-temperature preheating, temperature-rising heating, constant-temperature foaming and rapid cooling are carried out, and cooling annealing is carried out till room temperature is reached. Compared with the prior art, the pumice material made through the making method is free of toxin and harm, does not volatize and will not have a chemical reaction even if the pumice material is soaked in water for a long term, and is an environmentally-friendly material; meanwhile, the porosity is high, pores are moderate in size, and the pumice material is suitable for biofilm formation and proliferation of microorganisms and has a certain purification effect. A pumice body is firm, will not crack even under severe weather, and long in service life.

Description

technical field [0001] The invention relates to a pumice material, in particular to a pumice material used for the construction of artificial floating islands. Background technique [0002] Water eutrophication is a global water environment pollution problem. In terms of controlling the eutrophication trend of lakes and rivers and improving urban water pollution, many researches and attempts have been made at home and abroad, among which the ecological floating island technology is Widely used water restoration technology. Ecological floating island technology is also called "ecological floating island", "artificial floating island", "artificial biological floating bed", "biological floating bed" and "floating bed soilless cultivation" in some documents. Ecological technology has good effect, less pollution, low cost and easy assembly, so it is favored by scientific researchers and government personnel, and has begun to be applied to rivers and lakes on a large scale. At p...
