An environmental-friendly energy-saving stereoscopic biomembrane

Abstract

An environmental-friendly energy-saving stereoscopic biomembrane is disclosed. The stereoscopic biomembrane includes a membrane skeleton, a flower basket, a biomembrane and an aeration assembly. Netlike pattern weaving units are connected in order to each other through connecting points to form a stereoscopic netlike object provided with a plurality of round paths, and round fixing rings used for shaping are disposed in the paths according to process requirements, and therefore the round paths can ensure good aeration from bottom to top, microorganisms attached to the biomembrane are provided with sufficient oxygen, microorganisms free of vitality can be washed down and discharged along with water, biomembrane microorganism activity is increased, and the risk of blockage is eliminated. The disclosed biomembrane is stereoscopic so that a considerable biomembrane carrier surface can be generated, and the biomass is increased. The biomembrane is designed to have a stereoscopic structure and flowers and trees are planted in the flower basket, and therefore flow control can be achieved, no tension or significant load exists, energy is saved, the treating cost is reduced, the environment is beautified, pollutant emission is reduced, and waste water treating effects are greatly improved.

Description

technical field [0001] The invention relates to the technical field of sewage and wastewater treatment equipment, in particular to an environmentally friendly and energy-saving three-dimensional biofilm used for urban sewage or wastewater treatment. Background technique [0002] The biofilm method is a method of treating organic sewage by using microorganisms (ie, biofilm) attached to and growing on the surface of certain solid objects. Biofilm is an ecosystem composed of highly dense aerobic bacteria, anaerobic bacteria, facultative bacteria, fungi, protozoa and algae, and the solid medium attached to it is called filter material or carrier. The biofilm can be divided into anaerobic layer, aerobic layer, attached water layer and moving water layer from the filter material outward. The principle of the biofilm method is that the biofilm first adsorbs organic matter attached to the water layer, and is decomposed by the aerobic bacteria in the aerobic layer, and then enters t...

Problems solved by technology

[0005] However, a further disadvantage of the known spatial biofilm scaffolds is that it is difficult to arrange them to form a spatial structure and there is an increased risk of failure due to the loads connected in the nodes
