Low-carbon energy-saving method for treating polluted water quality of lake or landscape lake

Abstract

The invention belongs to a low-carbon energy-saving method for treating polluted water quality of a lake or a landscape lake, comprising an aeration type aerobic device, floating landscape aerobic devices, aquatic floating plants and cultured fishes, wherein the aeration type aerobic device is positioned in a water inlet of the lake or the landscape lake; the floating landscape aerobic devices are positioned in the lake or the landscape lake at intervals; the aquatic floating plants are distributed on the periphery of the lake or the landscape lake; and the cultured fishes are positioned in the lake or the landscape lake. The method mainly uses biological natural purification as a main method and mechanical purification as an auxiliary method, supplies power by using a clean carbon-free energy source, circularly increases the fluidity of a water body, can effectively purify polluted water, prevents phycophyta growth, improves the living environment of organisms in water and always retains aquatic oxygen content in a higher level. The invention has the advantages of simple operation, low treatment cost, low-carbon energy saving, no pollution, no noise, attractive appearance, environmental protection and good treatment effect.

Description

technical field [0001] The invention belongs to a low-carbon and energy-saving method for controlling the polluted water quality of lakes or landscape lakes. Background technique [0002] The water in the lakes or landscape lakes in the park is mostly stagnant water, especially the lakes or landscape lakes formed by using recycled water, that is, treated sewage, including landscape water features such as landscape pools. The flow makes the oxygen content in the water very low, and it is easy to cause a large number of algae plants to multiply. Most of these algae plants are densely covered on the surface of the water body, so that the oxygen in the atmosphere cannot enter the water, resulting in a long-term low oxygen content in the water. At the same time, after the death of algae plants, a large amount of toxic substance algal toxins are decomposed, causing a large number of fish in the water to die, making the water quality turbid, and causing the water to emit a fishy sm...

AI Technical Summary

Problems solved by technology

However, in the current water treatment industry, mechanical ventilation and aeration devices are complicated in equipment, high in energy consumption, high in water treatment costs, loud in operation noise, uneven in aeration, and poor in water oxidation effects, and often require a supporting power system for power supply, which limits The setting of aerators in large water areas such as lakes

Mechanical ventilation and aeration devices can only increase the oxygen content in water, but cannot reduce the growth and reproduction of algae plants. Now the method of inhibiting the growth of algae plants is similar to the method of killing weeds. Chemical herbicides are usually used, but in the process of inhibiting the growth of algae plants At the same time, chemicals seriously pollute the lake water, and chemicals are expensive and difficult to popularize

On the other hand, setting up aerators in parks such as lakes seriously affects the landscape of the park
