Types of Scenery Water

Scenery water generally refers to surface water bodies used for visual appreciation, which are generally divided into two categories: one is natural water features, such as natural rivers, lakes, and ponds; Another type is artificial water features, such as artificial lakes in small urban rivers, parks, and other scenic spots, as well as water spray pools and scenic fish ponds that are matched with real estate development.

The causes of landscape water pollution

When the landscape water shows phenomena such as algae growth, fish disease invasion, unclear water quality, ecological instability, and unsafe scenery, it is considered as landscape water pollution.

There are two main factors that contribute to the pollution of scenic water bodies: one is due to the invasion of foreign pollutants into the scenic water bodies, and the other is due to the inherent characteristics of the scenic water bodies.

The manifestation of external pollution includes: some urban waterways being used as discharge channels for various industrial wastewater, daily sewage, agricultural wastewater, etc. for a long time, which increases the pollution load in the water; Surrounding garbage, debris, dust, fallen leaves, or other pollutants entering the scenic water due to human activities or wind and rain factors, resulting in an increase in suspended solids and sediment in the water, and water pollution; Due to the influence of factors such as season and temperature (high temperatures in summer), moss and algae that reproduce invade the water, causing the color of the water to turn green and the water quality to deteriorate.

In addition, scenic water bodies also face inherent pollution factors caused by their own characteristics, such as water spray ponds and scenic fish ponds that are matched with real estate development. Generally, the water volume is small, the water is too shallow, and sunlight can directly reach the bottom of the water, promoting the reproduction of algae in the water; Although the artificial lake in the park has a large amount of water, its closure and poor mobility result in insufficient and untimely oxygen supply, leaving the already fragile ecosystem with no ability to resist external pollution; Furthermore, regarding some non natural artificial lakes, spray tanks, and scenic fish ponds, due to unreasonable shape planning during the initial design, their physical volume is not conducive to the flow of water, and the ability for water self purification is inherently lacking.

Management of Scenery Water Pollution

The purification of water quality in scenic water bodies mainly involves controlling COD The content of pollutants such as BOD, TN, TP, as well as the growth of algae (to prevent excessive reproduction), maintain the clarity and cleanliness of the water body, and restore the appreciation function of the water body. However, due to the special function and location of the scenic water body, the pollution management of the scenic water body is not suitable for the use of chemical agents and other chemical methods, nor is it convenient to use large mechanical and other physical methods; So, a good method is to enhance the self purification of the water body. To enhance the self purification ability of water bodies, it is necessary to accelerate the metabolic process of the biological ecological system of the water body itself; The metabolism of aquatic organisms and ecosystems mainly relies on the life activities of diverse organisms in the water environment.
