Problems solved by technology

my country's urban sewage treatment started relatively late. The sewage treatment plants built in the early stage generally separated the sewage and sludge treatment units due to the lack of strict sludge discharge supervision, and often ignored the sludge treatment, and even did not do it in order to save operating costs Any treated sludge is simply landfilled and piled up, causing the phenomenon of "sludge besieged city" to appear, which will bring great safety hazards to the ecological environment while encroaching on a large area of ​​land resources

Embodiment 1

[0044] 1. Preliminary preparation:

[0045] (1) On-site investigation: The test site is an artificial landscape lake in Wuhan University, which has been polluted by eutrophication;

[0046] (2) Raw material preparation: The sludge floating island unit in the composite artificial ecological floating island uses waste sludge from a sewage treatment plant in the suburbs of Wuhan as raw material, dehydrates and dries, and kills pathogens and parasites in it after high-temperature baking; light weight The material is polystyrene foam particles; the inorganic binder is high-sulfur HAS soil curing agent; the metal hook is a wire hook with a diameter of 4 mm; the algae biofilm carrier unit in the composite artificial ecological floating island is made of polyethylene (or polypropylene) ) semi-soft porous filler as raw material; the connection material between the algae biofilm carrier unit and the metal hook on the sludge floating island unit is light, waterproof and anti-corrosion ny...

Embodiment 2

[0061] 1. Preliminary preparation:

[0062] (1) On-site investigation: The test site is a waste storage pond (1000cm×800cm×200cm) in a factory in Wuhan City. Tap water and domestic sewage are poured into the pond to simulate eutrophic water body, and the water depth is 150cm;

[0063] (2) Raw material preparation: The sludge floating island unit in the composite artificial ecological floating island uses waste sludge from a sewage treatment plant in the suburbs of Wuhan as raw material, dehydrates and dries, and kills pathogens and parasites in it after high-temperature baking; light weight The material is polystyrene foam particles; the inorganic binder is high-sulfur HAS soil curing agent; the metal hook is a wire hook with a diameter of 4 mm; the algae biofilm carrier unit in the composite artificial ecological floating island is made of polyethylene (or polypropylene) ) semi-soft porous filler as raw material; the connection material between the algae biofilm carrier unit ...

Abstract

The invention discloses a composite artificial ecological floating island and a construction method thereof. The floating island comprises a sludge ecological floating island unit or a plurality of sludge ecological floating island units and a plurality of phycomycete biomembrane vector units. The construction method comprises the following steps: sludge powder which is subjected to innocent treatment, light materials and an inorganic adhesive are taken as raw materials to prepare the sludge ecological floating island units; porous macromolecular light suspension filler is simply processed toobtain the phycomycete biomembrane vector units; the phycomycete biomembrane vector units are pretreated and fixed on the sludge ecological floating island through flexible materials; and various floating island units are flexibly connected with each other through sponge or polystyrene foam. The composite artificial ecological floating island has raw materials available, low cost, stable chemicalproperties, friendly environment and no secondary pollution, reasonably utilizes waste sludge of sewage disposal plants, reduces urban sludge, and achieves the aim of reutilization of waste resources; and water purifying plants can be planted to form a miniature ecological community with microorganisms, have an all-around solid purification function on polluted water bodies, and the water purifying effect is better than that of a single floating island and phycomycete biomembrane vectors.

Description

technical field [0001] The invention relates to a composite artificial ecological floating island and a construction method thereof, belonging to the field of water environment treatment and ecological restoration. Background technique [0002] Eutrophication of water bodies is a common problem in the current world water environment. Rapid economic growth has brought heavy loads to various natural water bodies. Under the combined effects of foreign substances and endogenous pollution, excess nutrients in water bodies have caused excessive phytoplankton reproduction, resulting in deterioration of water quality. The eutrophication of rivers and lakes is essentially a problem of ecosystem degradation, and new ways to control water pollution should be explored with ecological concepts, ideas, and methods. [0003] Artificial biological floating island technology is a biological means for the restoration and treatment of eutrophic water. This technology is to artificially plant...
