Embodiment 1

[0026] Mix 3~6mm steel slag particles with 2~3mm anthracite and 4~8mm zeolite at a ratio of 1:1:1 as aggregate. Then mix the aggregate, CA50-G9 high-strength aluminate cement produced by Shanghai Yuxi New Material Technology Co., Ltd. and ferric oxide in a weight ratio of 50: 11: 1, and add 10% of the total weight of water , take the above-mentioned well-stirred materials to make pellets, and place them in a well-ventilated place to air-dry to obtain the desired finished product.

Embodiment 2

[0028] Take 3~6mm steel slag particles, mix with 2~3mm anthracite and 4~8mm zeolite each 820g, mix evenly, and use it as aggregate. Then mix the aggregate with 541g of CA50-G9 high-strength aluminate cement produced by Shanghai Yuxi New Material Technology Co., Ltd. and 49g of chromium oxide by weight, and add 305g of water. Take the above-mentioned well-mixed materials, put them into a 240mm×120mm×60mm abrasive mold, press them with a hydraulic pressing machine, and place them in a well-ventilated place to air-dry to get the desired finished product.

[0029] The way the finished product is used can vary depending on the shape of the finished product being made. For example, if the finished product is a material ball, it can be used in trickling filter bed, anaerobic biological filter, filter, biological aerated filter, high-load biological filter, active biological filter, etc.; The occlusal shape mold can be used as a revetment for rivers and lakes and fixed on the river o...

Abstract

The invention discloses composite ecological fillers and a preparation method of the composite ecological fillers. Adsorption functions of steel slag, anthracite and zeolite to nitrogen and phosphorus substances in sewage are utilized to optimize three types of fillers and enable the fillers to have a modularized characteristic. The composite ecological fillers are applicable to a trickling filter bed, an anaerobic biological filter tank, a filter tank, an aeration biological filter tank, a high-load biological filter tank, an active biological filter tank and the like, and can be used for river and lake slope protection materials.

Description

technical field [0001] The invention relates to a multifunctional composite ecological filler for water treatment, sewage and waste water treatment and a preparation method. Background technique [0002] In the existing technology, the traditional fillers are mainly in the shape of clay, ceramsite processed by rare earth, sand, and rings and balls made of high molecular polymers. Not only the mechanical properties are low, the surface area is small, but also there are problems in use. some problems. [0003] In recent years, the eutrophication process of urban rivers and lakes in China has been greatly accelerated, and the water bodies of most urban rivers and lakes are already in a state of severe eutrophication. The banks of urban rivers and lakes, as the transition zone connecting water bodies and land, are of great significance to increasing biodiversity in water bodies, system productivity, preventing soil erosion, improving water quality and beautifying the environmen...
