Landscape Water Treatment Methods Selection 1. Characteristics and Issues of Landscape Water Quality Landscape water pollution typically exhibits many unique characteristics, significantly different from domestic wastewater or pool water. For instance, artificial lakes commonly found in landscape water are often completely enclosed, unnatural lakes with very low self-purification abilities. Moreover, due to water source limitations, the primary source of replenishment for these lakes is often reclaimed water, which does not meet the quality standards for landscape water. This often results in excessive nitrogen, total nitrogen, and total phosphorus levels, exacerbating water pollution. The main pollution sources for typical enclosed, stagnant water lakes can be categorized into the following aspects: 1) Surface runoff from rainwater carrying organic matter and nitrogen-phosphorus nutrients from surrounding land and soil (referred to as "non-point source pollution"); 2) External organic matter and nitrogen-phosphorus nutrients brought by dust; 3) Organic matter accumulated from the continuous biological community development within the lake. For artificial lakes, it is expected that water quality will exhibit three types of pollution with different properties: 1) Eutrophication caused by an excess of nitrogen-phosphorus nutrients, manifested by the lake turning green, with an abundance of cyanobacteria and even algal blooms; 2) Organic pollution due to an excess of organic pollutants, characterized by turbid water, oxygen depletion, darkness, and an odor; 3) Impurity pollution caused by an excess of particulate matter, such as dust and leaves, leading to high levels of impurities, low water clarity, and affecting the aesthetics. Each type of pollution leads to water quality degradation and the direct destruction of the landscape. Therefore, it is necessary to implement targeted treatment measures for all three types of pollution to fully protect the water quality of artificial lakes. For landscape water treatment, the challenge lies in the large volume of water, with artificial lakes of tens of thousands of cubic meters being common. Urban large parks and landscape waterways can contain hundreds of thousands of cubic meters of water. If the methods of wastewater treatment or pool water treatment are directly applied, the cost of treatment per cubic meter is generally over $300, which means over $3 million for 10,000 cubic meters. This cost is prohibitive for landscape water treatment. Therefore, for the treatment of landscape water, it is necessary to solve the technical challenges and significantly reduce the cost of treatment, which is a difficult task. It is for this reason that landscape water treatment has become a global challenge. Year-round water change is not required, and the water is crystal clear, visible to the bottom!

Landscape Fish Pond Biological Filtration and Purification Project Scope
Soak the landscape fish pond with acidic substances to fully dissolve alkaline substances in the water (especially in cement).
Landscape fish ponds are cleaned and disinfected in accordance with water purification principles and technical requirements.
Bio-sand culture and backfilling within landscape fish ponds
Installation and debugging of circulating water pipelines and equipment for landscape fish ponds
Laying out electrical wiring within the landscape fish pond.
After completion of construction, introduce eco-purifying agent and eco-liquid into the pond.
Maintain relevant content within the contract term and monitor the water quality in the pool to ensure its quality.

How to cultivate fish first by nurturing the water
When changing water, leave some of the old water in the fish tank. The water used for the fish should be left in the sunlight for 24 to 72 hours. The new water should be similar in temperature to the old water. Add some salt to the new water to enhance the fish's disease resistance. Goldfish should not be overfed; uneaten food can spoil, causing the fish to become ill and affecting water quality. Method for changing goldfish water.

The principle of the landscape fish pond that requires no water change year-round
The Changzhou Hongbo Environmental Protection Engineering Co., Ltd. fish pond biological filtration and purification system, without damaging the original landscape fish pond, utilizes our company's practical research and experience to summarize filtration and purification methods, combined with physical filtration, achieving a year-round water change-free condition with crystal clear water visibility. The principle is as follows:
The landscape fish pond biological filtration system of Changzhou Hongbo Environmental Protection Engineering Co., Ltd. mainly consists of a recirculation pipeline, submersible pump, biological sand, and ecological liquid, forming a biological purification and physical filtration system. The recirculation pipeline and pump function to circulate water and increase oxygen levels; the biological sand, soaked and cultivated in the ecological liquid, forms a biological filter bed at the bottom of the pond. The pump network system gradually recycles and grinds the fish waste, leftover feed, and nutrients (including organic matter), absorbing them into the biological sand layer where they are decomposed and oxidized, producing volatile nitrogen gas and water. This also generates autotrophic beneficial bacteria, absorbs sunlight to inhibit algae and moss; it eliminates substances that degrade water quality, maintaining the clarity of the water.
Nutrients (including organics) →吸入through the pump network system into the bio-sand layer → undergo ecological liquid oxidation and decomposition → produce NO3 (salt) → denitrification by anaerobic bacteria → produce NO2 and NH4+ → further decomposed by aerobic bacteria → produce N2 and H2O, volatilize. (Autotrophic bacteria → absorb sunlight → inhibit algae, moss, etc.)
Fishkeepers know that frequent water changes affect the fish, especially koi, which are prone to illness when faced with new water quality, especially when the water temperature difference exceeds 6 degrees, directly leading to problems for the koi. After years of research, the biological pond purification system equipment has taken into account various factors, summarizing the best methods and experience. This system is favored by fishkeeping enthusiasts, bringing a true revolution to the fishkeeping industry, demonstrating the power of science and the progress of society.
