Method for purifying water systems of mountain landscape lakes

Abstract

The invention relates to a method for purifying water systems of mountain landscape lakes. The method includes measures of 1), leading mountain water sources to settling and filtering devices via pipelines, settling impurities, filtering sandy soil and then draining the mountain water sources into the mountain landscape lakes; 2), arranging front pools and rear pools, respectively connecting the front pools and the rear pools with municipal blow-down pipelines, communicating the mountain landscape lakes with the rear pools and connecting the rear pools with the municipal blow-down pipelines by water level adjusting pipes; 3), growing a circle of water retention plants on a peripheral mountain slope of each mountain landscape lake, and arranging a circle of passages around each mountain landscape lake on a lakeside wetland of the mountain landscape lake; 4), releasing algae eating insects in lake surface regions of the mountain landscape lakes, growing submerged plants in lakebeds, releasing benthic organisms and constructing 'algae eating insect-submerged plant-benthic organism' coexistence ecology. Main fillers for roadbeds include cobblestone and sand, and water-permeable geotextile is arranged under the roadbeds. The method has the advantage that the water systems of the mountain landscape lakes can be purified by the aid of the method and have flood discharging capacity.

Description

technical field [0001] The invention belongs to the field of purification of landscape lakes, and in particular relates to a method for purifying the water system of mountain landscape lakes. Background technique [0002] Mountain landscape lakes are generally set at the foot of a mountain or in a valley. In addition to rainwater, there are two water supplies. One is that the mountain water is introduced through pipelines, and the other is that the mountain rainwater is imported through the hillside. Both of these water supply methods will be mixed with mud and sand. Especially in heavy rainy days, it is more likely to cause water pollution in mountain landscape lakes. Due to its large size and the inability to exchange water as a whole, the mountain landscape lake is a nearly closed water system. In a closed water system, organisms in the water are prone to corruption and cause water pollution. When the rain is heavy, if the mountain landscape lake does not have flood disc...

AI Technical Summary

Problems solved by technology

When the rain is heavy, if the mountain landscape lake does not have flood discharge measures, and the surrounding area is washed out to expose the soil, the water body will easily become turbid, which will not only cause serious pollution but also affect the landscape effect

[0003] At present, there are methods to purify the landscape lake water system in the city, but these methods cannot complete the filtration and purification of water supply in multiple places, nor can they complete the functions of flood discharge and water regulation
