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

[0045] 1. Preliminary preparation:

[0046] (1) On-site investigation: The test site is an artificial landscape lake in Wuhan University, which has been polluted by eutrophication;

[0047] (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, dehydrated and dried, and baked at high temperature to kill pathogens and parasites; light weight The material is ESP foam particles; the inorganic adhesive uses high-sulfur HAS soil curing agent; the metal hook uses a wire hook with a diameter of 4mm; the algae biofilm carrier unit in the composite artificial ecological floating island is made of polyethylene (or polypropylene) half The soft porous filler is the raw material; the connecting material between the algae biofilm carrier unit and the metal hook on the sludge floating island unit is made of lightweight, waterproof and anticorrosiv...

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 to obtain 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 chemical properties, 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, belonging to the field of water environment management and ecological restoration. Background technique [0002] Eutrophication of water bodies is a universal problem in the current world water environment. The rapid economic growth has brought heavy loads to various natural water bodies. Under the combined effects of external substances and endogenous pollution, excess nutrients in the water bodies cause excessive reproduction of phytoplankton, resulting in deterioration of water quality. The eutrophication of rivers and lakes is essentially an issue 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 bodies. This technology is to artificially plan...
