Open-air circulating pool for simulating ecological damage

An open-air circulating pool for simulating ecological damage, provided with a set of equipment for simulating ecological damage, comprising an open-air wave-flow circulating pool, an additive injection device and an ecological indicator sampling and detection device, wherein connections and roles of the set of equipment in an ecological damage simulation test are as follows:

• the additive injection device is able to inject a sediment, test water, an algae, a cement block, a nutrient and a pollutant into the open-air wave-flow circulating pool to simulate, by a wave-flow circulating system of the open-air wave-flow circulating pool, natural ecological environments of different water quality and sediments, as well as changes in water bodies caused by a sea occupation project, discharge of a typical pollution source and a sudden leakage accident;
• the ecological indicator sampling and detection device is able to put a collector to a certain position in the open-air wave-flow circulating pool to collect a sample;
• the sample is then sent to a laboratory for detection and analysis according to a standard method to acquire water quality, sediment and biological indicator data such as total nitrogen (TN), total phosphorus (TP), pollutant load, algae cell concentration, chlorophyll-a content, particulate matter concentration, biological composition and particle size distribution;
• alternatively, a detection probe is directly put into the open-air wave-flow circulating pool to acquire water quality indicator data such as temperature, dissolved oxygen (DO), pH and electrical conductivity;
• these ecological data reflect changing trends of an aquatic organism and an environmental factor, and provide a test basis for qualitatively and quantitatively determining a law of causality of damage by a sea occupation project, discharge of a typical pollution source and a sudden leakage accident.
