Preparation method of ecological porous concrete for oily sewage treatment

Abstract

The invention discloses a preparation method of ecological porous concrete for oily sewage treatment. Modified ceramic polishing aggregate water-permeable oil-blocking concrete in the ecological porous concrete is positioned on a lower layer; an oil discharge pipeline is vertically arranged in the modified ceramic polishing aggregate water-permeable and oil-blocking concrete, an oil-permeable andwater-blocking modified copper net is arranged at an opening in the top of the oil discharge pipeline, and the modified ceramic polishing aggregate oil-permeable and water-blocking concrete is locatedover the oil-permeable and water-blocking modified copper net; the ceramic polishing aggregate water-permeable concrete is located over the modified ceramic polishing aggregate water-permeable and oil-blocking concrete, and the water-permeable and oil-blocking modified copper net is located between the ceramic polishing aggregate water-permeable concrete and the modified ceramic polishing aggregate water-permeable and oil-blocking concrete. The prepared ecological porous concrete can be used for effectively treating oily wastewater on the ground, so that oil stains and water can be selectively separated, and the permeability of the ecological porous concrete is not influenced.

Description

technical field [0001] The invention relates to the field of permeable concrete, in particular to a method for preparing ecological porous concrete used for oily sewage treatment. Background technique [0002] Permeable concrete, also known as porous concrete, is a kind of concrete with internal interconnected pore microstructure formed by reducing or avoiding the use of fine aggregates, and is a functional material with high water permeability. The main purpose of the application of permeable concrete is to protect water resources, the environment and prevent flooding during the rainy season in the city. Its main function is to infiltrate the rainwater flowing through the surface into the soil with the high permeability of permeable concrete, so as to maintain local areas. The purpose of the underground water table is to reduce the drainage load of the urban drainage system and the accumulation of rainwater in low-lying areas. [0003] For oily sewage, in order to prevent ...

AI Technical Summary

Problems solved by technology

The absorbed oil will easily block the permeable channel, thus making the permeable concrete lose its permeable function

There are also some schemes that use modified aggregates to form an oil-proof layer, but oil-proof and waterproof layers will also be formed at the same time, causing the concrete to lose its permeability function
