Embodiment Construction

[0027] The device for lake eutrophication control using industrial waste provided by the present invention is mainly composed of three parts: closed front storage, micro-electrolysis constructed wetland, and nano-aeration channel; wherein:

[0028] There is a micro-vortex coagulator 4 inside the closed front storage 5, and the water outlet of the closed front storage 5 is connected to the water inlet of the micro-electrolysis artificial wetland 7, and a dosing device is buried in the water inlet of the micro-electrolysis artificial wetland 7 1. Micro-electrolysis constructed wetland 7 is filled with micro-electrolysis iron-carbon filler 6, which is a mixture of iron filings, crushed stones, slag, etc., so as to implement the technical scheme of treating waste with waste. The plants 2 are planted on the micro-electrolysis iron-carbon filler, and the plants planted in the micro-electrolysis artificial wetland are calamus and quinces.

[0029] The outlet water of the micro-elect...

Abstract

The invention discloses a device for using industrial wastes to control lake eutrophication. A micro vortex coagulation device is arranged in a closed pre-dam; effluent water of the closed pre-dam enters a micro-electrolytic constructed wetland; the micro-electrolytic constructed wetland is filled with micro-electrolytic iron-carbon fillers; plants grow on the micro-electrolytic iron-carbon fillers; one dosing device is buried at a water inlet position of the micro-electrolytic constructed wetland; the effluent water of the micro-electrolytic constructed wetland enters the closed pre-dam and a nano aeration river respectively; a nano aeration tray is arranged in the nano aeration river; a necking aeration head is arranged above the nano aeration tray; carbon fiber fillers are perpendicularly laid above the necking aeration head; an ecological floating island floats on the surface of the nano aeration river; plants grow on the ecological floating island; the other dosing device is buried at a water outlet position of the nano aeration river; effluent water of the nano aeration river is connected to the inflow water of the closed pre-dam. The invention further discloses a method for lake eutrophication. With adoption of the device, the content of aromatic ring substances in the treated sewage is reduced by more than 99%.

Description

technical field [0001] The invention relates to a device for reducing eutrophication substances (such as nitrogen, phosphorus, potassium nutrients, organic pollutants, heavy metals, etc.) in water bodies of urban lakes, in particular to a device for controlling lake eutrophication by using industrial waste. [0002] The present invention also relates to a method for controlling lake eutrophication by using the above-mentioned device. Background technique [0003] Pollution and eutrophication of lakes and reservoirs are one of the major environmental problems in my country. Years of research by relevant scientific research and environmental protection monitoring units show that some urban lakes in my country have reached the level of moderate trophication and heavy eutrophication. Facts have proved that most urban lakes in my country have reached the level of eutrophication or super eutrophication. Urban lakes and reservoirs are important water sources for cities, which can...
