Artificial lake treatment equipment

一、Aeration Method: Use aeration device to increase oxygen directly.

Using aeration device to filled the water with oxygen and increase the amount of dissolved oxygen in water to achieve the purpose of water purification. The equipment used in this method is mostly fountain water drop device, ordinary aerator or flotation device. The method can effectively solve the black body phenomenon of water, improve the water and animal and plant growth environment.



The air floatation method is the formation of highly dispersed microbubbles in water, adhering to the hydrophobic base of the solid or liquid particles in the waste water to form a water-gas-particle three-phase mixed system. After the particles adhere to the bubbles, the surface density is less than that of the water body floating to the surface, the formation of scum layer was scraped, in order to achieve solid or liquid separation process.Air floatation is divided into superficial shallow air flotation, vortex air flotation and advection air flotation. It is currently used in water supply, industrial wastewater and municipal wastewater treatment.


Air Flotation Advantages
1、Dissolved gas tank produces small bubbles whose size is 20-40um, adhesive flocculation is solid and air float effect is good;
2、Less use of flocculant, cost is reduced;
3、Easy to operate, water quality and water easy to control, simple management;
4、With anti-flushing system, the release is not easy to plug;
5、High degree of purification, suspended solids removal rate is 90% or more.



二、Mechanical Filter: sand filter, circulation pump etc.

Resilience Sand Filter (Fiberglass)

Features
1、The filter is shaped by fiberglass reinforced plastic.
2、Abrasion-resistance, corrosion-resistant and durable.
3、Easy to install and maintain
4、In-built drain valve and pressure gauge, make maintenance easier.
5、The best water supply design make flow more stable.



Resilience Sand Filter (Metal)


Features
1、The components inside employs stainless steel material, which is durable.
2、The inside is connected to the main tank with flange, which is easy to install and maintain.
3、The structure of water collecting system is reasonable, with steady flow and thorough backwash.
4、Double view mirror is used for viewing. You can see the internal filtration membrane and the change of water quality.
5、A emptying outlet is at the bottom of the filter. When the filter needs to be maintained or the filtration media needs to be replaced, you can empty the filter through the outlet.

三、Microecological Method

Biological treatment is using the microorganisms to make further decomposition on organic pollutants and nutrients, so as to further improve water quality, so that the water pollutants are significantly reduced,which will create ecological and environmental conditions for aquatic organisms, especial- ly thesurvive and multiply of submerged plants,and finally restore the water ecosystems. The processing method has the following advantages:



Bionic aquatic weed and carpet

Advantages
1、Strong adsorption capacity;
2、Provide attachment place microorganism to the microorganism, thereby reduces the suspended matter;
3、They are made of polymer material, without replacement and care.
4、Construct underwater ecological system with water aeration device
