Landscape water production algae treatment method



For the pollution of landscape water bodies, specific methods and measures are adopted to make the water quality of the landscape water reach the various indicators of the landscape water quality specified by the state, and at the same time restore the ornamental process, called landscape water treatment.

As people's requirements for the quality of work and living environment continue to improve, waterscape as an important part of the landscape, more and more people's attention and love. A good water view will not only make the whole garden landscape dazzling, but also enable people to fully feel the joy brought by nature. However, once the water quality of the waterscape deteriorates, it not only makes the entire landscape lose its ornamental value, but even becomes a heavy burden on people's minds.

There are two main reasons for the pollution of landscape water bodies:

1. Pollution caused by the characteristics of the landscape water body (internal cause)
1 The water quality of the landscape water body is generally poor. 2 The water volume is small, the liquidity is poor, and the ecosystem is fragile. 3 Design defects
Second, and pollution caused by the invasion of foreign pollutants (external causes).
1External pollutants directly pollute the water body 2 Invasion of dust, defoliation and garbage 3 Pool bottom, slope protection breeding moss

In addition, most of the landscape water bodies are completely closed, and the self-purification capacity is extremely low. Due to water source restrictions, most of the main supplementary water sources are medium water, and ammonia nitrogen, total nitrogen and total phosphorus are seriously exceeded, which will increase water pollution.

The water quality maintenance of landscape water is mainly to control the content of COD, BOD, TN, TP and other pollutants in the water body and the growth of algae (so that it does not overproduce), and keep the water body clear and clean.
Common methods of landscape water treatment include traditional materialized treatment and ecological treatment.

(1) Physical law

1 diversion and water exchange
When the suspended solids (such as mud, sand, and organic matter) in the water body increase, the transparency of the water body decreases, and when the water quality is chopped, the impurity concentration can be reduced by water diversion and water exchange.
Disadvantages: There must be enough clean water source as a guarantee, the cost of water change is high, and environmental pollution is caused. Used only in the case of small amounts of water.

2 cycle filtration equipment
Sand cylinder filter

According to the size of the water body, the design filter sand tank and circulating water pump are designed to lay the pipeline for circulating landscape water. The essence of the sand tank filtration is to gradually purify the water through the processes of membrane filtration, permeation filtration and contact filtration. In the engineering case, the landscape water with more suspended solids (SS) or sediment is treated, and the effect is still good.
Disadvantages: It can only be used in the landscape waterscape with a small water area. If the amount of water is large, the cycle filtration cycle will be prolonged, and the expected effect will not be achieved; the inhibition and treatment of organic matter and algae will not be effective.

Automated high efficiency fine filter

1. Change to static motion: The KLWT hydraulic flotation water treatment system is adopted. The water surface of the landscape lake forms upstream and downstream, and the static lake surface forms a flow. It creates the possibility that the water will not be rotted and the water body will be self-cleaning. It also makes clear flow of water in the narrow river channel, which increases the natural wildness and dynamic emotions in the garden.

2. Water circulation treatment: All water in the water body should enter the hydraulic flotation and oxygenation treatment system in a continuous manner. After five major functions of the system, it is renewed and renewed, so that the whole lake enters a virtuous circle, and dissolved oxygen always reaches saturation level. Fresh, activated, always unchanged, no odor, forming a virtuous circle.

3, the water quality is excellent: the lake is clear and pleasing to the eye. Always keep the low turbidity of the lake, have a good transparency, and make the blue waves ripple. All lakes have "immunity" and contain appropriate amounts of bactericidal factors. The lake water is not only basically sterile, but also has a small antibacterial ability.



The characteristics of this new landscape circulation water treatment system are:

1. National patent, forward-looking technology, saving water 80% / saving medicine 100% (less than disinfectant)

2. The equipment is operated by gravity, the power head is only 5 meters, and the flushing pump saves more than 80% of the power.

3. Multi-layer repeated and natural filter material, automatic backwashing, automatic alignment, no-knot, never replaced

4. Automatically introduce oxygen in the air, increase dissolved oxygen, activate water, freshen, and make the water benign

5. Under normal circumstances, it is forbidden to add coagulant, coagulant and algaecide to avoid chemical pollution.

6. The equipment is compact in structure, simple in installation space, small in floor space, and saves 50-70% of civil works.

7. Hydraulic fully automated system, no need for full-time staff maintenance, saving manpower 100%

8. The effluent turbidity is 0.4-1mg/L, the pool water will never change, the sky blue is always transparent, and the water quality is better than the national standard.

9. According to the internal interception of the equipment, timely backwashing, uninterrupted water supply during the cleaning process, minimal pipeline pressure

10.Using a combined, low-speed energy-saving water pump, saving a lot of operating costs compared to other types of water treatment equipment

11. All UPVC materials, non-toxic, non-corrosive, no maintenance, equipment warranty for more than 30 years

This equipment basically has no shortcomings. The amount of water can be adjusted according to the actual situation, saving water, saving electricity, filtering effect, and fully automated operation. long lasting.

3 algae killer
Commonly used are ultraviolet algae killer, ultrasonic algae remover and so on. It can play a role in a short time, has a certain effect, directly inhibits algae cells, and is flexible and convenient. The ablation instrument can only be used as an auxiliary method for landscape water treatment. Ultraviolet tubes require maintenance and ultrasonic waves emit noise.

4 artificial aeration
Manual aeration of water to increase the amount of dissolved oxygen in the water, to maintain aerobic state, to prevent black body odor. Pure oxygen aeration can reduce organic pollution of water body, increase dissolved oxygen concentration, enhance self-purification ability and improve ring in a short time.
