Solar De-Layer Aerator
SLA-LJ solar de-layer aerator: It is a kind of oxygen-enhancing aeration and water circulation equipment suitable for water pollution control. Using solar energy as a power source, it has the advantages of low operation and management cost, good oxygen-enhancing effect, large flow, anti- Features such as clogging, long life and low operating noise. The de-layered solar aerator is suitable for water bodies such as rivers, lakes, reservoirs, artificial lakes and other water bodies with insufficient power supply conditions.
SLA-LJ solar delamination aerator water purification principle:
The de-layered solar aerator uses solar energy as the direct driving force for the operation of the equipment, and is equipped with a unique rotary cutting and pulling aeration impeller. Through the rotating and lifting action of the impeller, the oxygen-deficient water at the bottom is transferred to the surface of the water body and mixed with the surface oxygen-rich water; The rich water in the surface layer diffuses horizontally and horizontally through centrifugal rotation, and enters the anoxic zone in the bottom layer vertically.
In this way, the triple effects of water body disintegration, oxygenation and vertical and horizontal circulation exchange are realized, and the super-saturated dissolved oxygen water in the surface layer is transferred to the bottom of the water body with high strength, which increases the dissolved oxygen in the bottom water body, eliminates natural stratification, and improves the self-purification capacity of the water body.
Equipment parameters and selection
Before selecting the SLA-LJ solar De-layer aerator, the oxygen demand of the water body, the plane size of the water body and the depth structure must first be determined.
Features of solar de-layered aerator:
◊Low cost, quick effect, easy installation, no need for daily manual operation;
◊Using corrosion-resistant materials such as stainless steel and engineering plastics, with long service life;
◊Ecological and environmental protection, no chemicals are added, no secondary pollution;
◊Unpowered laminar flow operation to realize large-flow water circulation;
◊The equipment floats on the water surface, do not install the foundation, and is not affected by the water level;
◊Applicable to river treatment, lake treatment, reservoir treatment, rural water treatment
SLA-LJ solar de-layer aerator has the following functions:
Upper and lower exchange mixed reoxygenation: the delamination process is a mixed reoxygenation process, which transfers the dissolved oxygen-rich water in the surface layer to the bottom layer, increases the dissolved oxygen content in the bottom water body, prevents the water body from deteriorating due to lack of oxygen, and prevents sulfides, amines and other chemical substances are emitted to promote the biochemical water purification effect of the bottom water body. At the same time, the oxygen-rich water bottom prevents the anaerobic release of phosphorus, and the suspended mud can effectively adsorb dissolved phosphide.
Stimulates the ability of environmental self-purification: when the temperature of the bottom water increases and the dissolved oxygen increases, it decomposes the harmful substances such as animal excrement, organic sludge and putrefying algae deposited at the bottom, improves the sediment, activates the ecological function of the sediment, and the self-purification load of the water body is obtained. improve.
Powerful circulation to produce living water: Living water is the life of the lake, and the delamination equipment forms a strong main water flow and induction flow, which can effectively break the natural stagnant water zone formed by the thermocline, so that the entire water body forms a circulating living water flow.
Inhibit and reduce the occurrence of algal blooms: By de-stratification, the stratification of dissolved oxygen, temperature and salinity in the water body is eliminated, and the water quality is stabilized. The high-concentration algae-containing water in the surface layer is transferred to the bottom, and is inhibited under low temperature and no light conditions. The surface algae is rapidly reduced, and part of it is eliminated by the feeding of the bottom plankton, which can eliminate the bloom and prevent it from happening again.
Resource utilization of pollutants: The high concentration of algae in the surface water body is transferred to the bottom of the water body and becomes the bait for fish and shellfish.
Improve the appearance and improve the ecology: The equipment can reduce the biochemical oxygen demand (BOD), reduce the suspended solids (TSS) in the water, improve the visibility of the water body, remove the odor and degrade the sludge at the bottom of the water body in the short term. At the same time, it prevents seasonal fish kills and inhibits the growth of harmful aquatic weeds.
Engineering Applications:
Solar decomposed aerator is suitable for water treatment and ecological restoration of urban rivers, black and odorous rivers, artificial lakes, natural lakes, etc. In addition, the delaminated solar aerator can also be applied to municipal and industrial sewage treatment, tap water sources and other water bodies.
There are two types of solar delamination aerators: one-piece structure and split-type structure. One of its important features is the floating installation method, which is easy to install. There is no need for a special installation foundation, and the installation position can be flexibly adjusted according to needs.
The solar de-layer aerator can adopt various fixing methods such as plug-in type, anchor type, and revetment pulling type.
Plug-in type: suitable for natural mud bottom waters with water depth less than 3M;
Anchor type: suitable for deep, wide reservoirs or large lakes;
Revetment pulling type: suitable for narrow rivers without flood discharge requirements.
