Description

TECHNICAL FIELD

[0001] The present application belongs to the field of water treatment environmental protection equipment for removing pollutants in local water area, in particular to a local water area algal bloom prevention and control integrated device for eliminating local water area algal bloom and preventing excessive growth of algae. BACKGROUND

[0002] In rivers, lakes and reservoirs, especially rivers, lakes and reservoirs of drinking water sources, excessive growth of algae can have serious negative impacts on ecological environment, human health and social economy, etc., mainly including:

[0003] Water body hypoxia: Algae grow in large quantities, and consume a large amount of dissolved oxygen in water during respiration at night, causing a sharp decrease in the content of dissolved oxygen in water, which may affect the survival of other organisms in water. At the same time, after the death of a large number of algae, the decomposition process will also consume a large amount of dissolved oxygen in water, leading to serious hypoxia in water body, forming "hypoxic zone" or "dead water zone", and even causing suffocation and death of fish and other aquatic organisms due to hypoxia.

[0004] Reducing water transparency: A large number of algae gathered on the surface of water body will block sunlight from entering the lower layer of water body, affecting the photosynthesis of aquatic plants, even leading to their death, and affecting other aquatic organisms that rely on these plants for survival. At the same time, the large amount of algae will reduce the transparency of water body, affecting the landscape effect of water body.

[0005] Affecting food web structure: The large-scale reproduction of dominant species of algal bloom will inhibit the growth of other algae, thus changing the phytoplankton community structure and destroying the normal food chain foundation. At the same time, some organisms that feed on algae may temporarily have sufficient food due to the excessive increase in the number of algae, but the following water quality deterioration and oxygen deficiency will lead to the mass death of these organisms, thus affecting the stability of the entire food chain.

[0006] Causing secondary pollution: Some algae produce algal toxins or odor-causing substances during metabolism. Algal toxins can have toxic effects on aquatic organisms, causing biological growth inhibition, reproduction decline, even death, etc.; odor-causing substances can cause water body odor, thus affecting water quality safety and water body sense.

[0007] Drinking water safety risk: Algal bloom and algal toxins produced thereby can pollute drinking water sources. Conventional water treatment processes may not be able to completely remove some algal toxins, which requires additional treatment cost and technical difficulty. If not properly treated, there may be residual algal toxins. These algal toxins entering the human body can cause acute or chronic poisoning, causing symptoms such as liver damage, diarrhea, vomiting, etc., and long-term exposure may increase the risk of liver cancer.

[0008] Contact health hazards: Direct contact with the water body or aerosols (such as water mist caused by motorboats) during swimming, playing, boating or other water activities in waters with algal blooms may irritate the skin, eyes and respiratory tract, trigger allergic reactions or inflammation.

[0009] Food safety risks: Shellfish (such as oysters, mussels, clams) and fish can accumulate algal toxins in their bodies. Eating contaminated seafood such as shellfish or fish can transmit algal toxins to humans through the food chain, which can cause food poisoning, and is one of the main ways that algal toxins harm human health.

[0010] Fisheries and aquaculture losses: Algal blooms cause water hypoxia and water quality deterioration, directly causing mass mortality of fish, shrimp, shellfish and other aquatic animals, or making aquatic products contaminated by algal toxins unsuitable for sale, which brings a blow to fishing and aquaculture industries and causes economic losses.

[0011] Tourism and landscape value loss: Algal blooms cause water odor, water color abnormalities, biological death, and related health warnings, which can severely affect the landscape of tourist attractions such as lake resorts, leading to a decrease in tourists and a decline in tourism revenue. Algal blooms in urban landscape water bodies (such as park lakes, artificial river channels, etc.) can affect the city's image and residents' quality of life.

[0012] Algal blooms are caused by a complex combination of factors, mainly including the following aspects: 1. Water eutrophication Excessive nitrogen, phosphorus and other nutrients provide sufficient nutrients for algal growth and reproduction.

[0013] 2. Suitable light and temperature conditions Sufficient light (such as long summer days) can promote algal photosynthesis, accelerate cell division, and promote rapid growth and reproduction of algae. In addition, generally at 20 - 30℃, algal physiological activities are vigorous, and growth and reproduction speed up.

[0014] In water bodies with relatively slow water flow, algae are extremely easy to gather and grow. For example, in lakes, reservoirs and other water bodies, due to poor water exchange, algae are provided with a stable growth environment, which is conducive to the reproduction of algae, and thus algal blooms occur.

[0015] The most direct and effective method in the prior art for preventing and controlling algal blooms in rivers, lakes and reservoirs, especially in drinking water sources, mainly includes: (1) reducing the input of nutrients to reduce the degree of water eutrophication through source control; (2) reducing the density of algae by salvaging and removing algae in the local water area where algal blooms occur; (3) increasing the flow of the local water area to prevent the aggregation and reproduction of algae; and (4) increasing the dissolved oxygen content in the local water area by an aeration device to inhibit the aggregation of algae and improve the purification capacity of the water body.

[0016] How to achieve integrated comprehensive management of efficient algae salvaging, local water flow enhancement and local water dissolved oxygen content improvement to effectively eliminate and prevent algal blooms is a key problem that needs to be solved in the current technology. The existing management means mainly focus on a single link (such as mechanical salvaging or aeration oxygenation), lack of synergistic mechanism, resulting in low efficiency of algal bloom emergency treatment and high long-term prevention and control cost. The core of the integrated device is to realize the trinity function of "salvaging-disturbing-oxygenation" through technology integration, to simultaneously realize algae aggregation salvaging and water circulation enhancement, which can not only slow down the progress of algal blooms in the early stage of algal bloom, but also quickly reduce the biomass of algae during the algal bloom process, and also can inhibit the secondary outbreak of algae by improving the hydrodynamic conditions. The device has important application value for guaranteeing the safety of drinking water sources and maintaining the ecological balance of landscape rivers, lakes and reservoirs.

[0017] The present application discloses a local water area algal bloom prevention and control integrated device for simultaneously realizing efficient algae salvaging, local water flow enhancement and local water dissolved oxygen content improvement to solve the problem of local water area algal bloom prevention and control.
