What are the processes of landscape water treatment? 5

Aeration method uses an aeration device to fill the water body with oxygen and increase the content of dissolved oxygen in the water body to achieve the purpose of water purification. The equipment used in this method is mostly fountain water drop device, ordinary aerator, etc., for the closed and non-flowing landscape water body, the aeration device can only oxygenate a small area around its equipment, resulting in a large number of anoxic dead ends, and can not make the water body uniformly oxygenated. Moreover, this method can only improve the black and odorous phenomenon of the water body, and has no obvious treatment effect on the inhibition of algae and the realization of clear water quality.

Circulating filtration method] According to the physical principle, the impurities in the landscape water body are separated from the water body to keep the water quality clean. This method usually uses the method of sprinkling chemicals to form precipitation with pollutants in the water as an auxiliary to form a set of landscape water treatment schemes. In the engineering example, this method has a good effect on the treatment of landscape water bodies containing more suspended solids (SS) or sediment.

However, if the water body area is slightly larger, the cycle of circulating filtration must be prolonged, so that the water quality can not achieve the expected effect, and the method has little effect on the inhibition and treatment of organic matter and algae, and the addition of chemical agents is easy to produce secondary pollution to the water body, so the general circulating filtration technology is only used in the landscape fountain waterscape with a small water body area.

HDP direct purification method] combines physical technology with microbial technology, adopts the integrated device of push flow and aeration to create a huge water flow in the closed landscape water body, and efficiently aerates, so that the oxygen-rich water block is fully mixed with the surrounding oxygen-poor water block with the water flow, and the ecological environment in the water is improved. Compared with the circulating filtration method, the number of water circulation is greatly increased. At the same time, special microbial carriers are placed in the water body, and the original indigenous microorganisms in the water are naturally attached to it, grow and multiply in large quantities, efficiently decompose pollutants in the water, strengthen the self-purification ability of the water body, and can prey on and decompose algae, without secondary pollution.

Eh, I occasionally found this on the map, you can consult yourself, I don't know if I can help you.

A certain method cannot be used in general, and the process should be determined according to the actual situation.

The treatment method of landscape water can take different measures according to the specific situation and needs. Here are some common landscape water treatment methods:

Rainwater harvesting: Rainwater harvesting systems are used to collect rainwater for watering plants and other landscaping water needs. This can reduce reliance on tap water and lower water bills.

Water-saving irrigation is a system that minimizes water waste by using a high-efficiency water-saving irrigation system, such as drip irrigation, sprinkler irrigation or micro-sprinkler irrigation systems. These systems are able to deliver water directly to the roots of the plant, reducing water evaporation and weathering losses.

Plant selection: Choosing plants that are adapted to local climatic conditions and soil types can reduce the need for water resources. Drought-tolerant and native plants generally have lower water requirements and are suitable for landscape design.

Soil Improvement: Improving the texture and water-holding capacity of the soil can improve the infiltration and retention of water. The addition of organic matter, mulch, water-retaining agent, etc., can reduce water loss, and Nogami can increase the water-holding performance of the soil.

Regularly inspect and fix water leaks: Regularly inspect pipes, valves, and sprinklers in your landscape irrigation system to ensure there are no water leaks. Timely fixing of water leaks can reduce water waste.

Irrigation planning and time control: According to the needs of plants and local climatic conditions, the irrigation plan is reasonably formulated, and the automatic irrigation control system is used to control the irrigation time and water consumption.

Water recycling: Water resources can be recycled by connecting water bodies such as ponds, pools, and rainwater traps to irrigation systems. Reusing wastewater for irrigation or other non-potable purposes after proper treatment is also an effective method of water recycling.

These methods can help reduce landscape water use, improve water use efficiency, and reduce environmental impact. Depending on the specific scenario and needs, the appropriate treatment method or a combination of methods can be selected to implement landscape water management.

At present, there are several types of water treatment technologies:

1. Coagulation and sedimentation method Coagulation and sedimentation method is a method of purifying industrial wastewater by using coagulants.

2. Adsorption method The adsorption method is to use adsorbents to treat wastewater.

3. Biodegradation method. At present, printing and dyeing and papermaking wastewater are the two main factors causing environmental pollution.

4. Ion exchange resin method Ion exchange resin (IER) is a synthetic functional polymer material containing active groups, which is formed by the introduction of cross-linked polymer copolymers with different properties of ion exchange groups.

5. Membrane separation technology In industrial wastewater treatment, the application of membrane separation technology can treat all kinds of wastewater.

Water treatment is the process of improving the water quality by physical, chemical, biological and other methods for source water or water that does not meet the requirements of water quality. In layman's terms, it is the process of "turning the water you have into the water you need", and the effect of water treatment can be measured by water quality standards.

Water treatment methods can be summarized into three ways: 1. The most commonly used is to obtain the required water quality by removing some or all of the impurities in the raw water; 2. Obtain the required water quality by adding new components to the raw water; 3. The processing of raw water does not involve the removal of impurities or the addition of new components. Commonly used water treatment agents are:

Polyaluminum chloride, polyaluminium ferrochloride, basic aluminium chloride, polyacrylamide, activated carbon and various filter materials, etc.

Water treatment is the process of removing some substances in water that are not needed for production and life through physical and chemical means. It is a process of water quality conditioning such as sedimentation, filtration, coagulation, flocculation, corrosion inhibition and scale inhibition for specific purposes.

According to the different requirements of the industry, the process of producing ultrapure water can be roughly divided into the following four types:

1. The ion exchange method is adopted, and the process is as follows:

2. The two-stage reverse osmosis mode is adopted, and the process is as follows:

Raw Water Raw Water Pressurized Pump Multi-media Filter Activated Carbon Filter Water Softener Precision Filter Primary Reverse Osmosis pH Adjustment Intermediate Water Tank Secondary Reverse Osmosis Purified Water Tank Pure Water Pump Microporous Filter Water Point.

3. The EDI method is adopted, and the process is as follows:

4. Raw water, multi-media filter, activated carbon filter, water softener, intermediate water tank, low-pressure pump, pH adjustment, high-efficiency mixer, precision filter, high-efficiency reverse osmosis, intermediate water tank, EDI water pump, EDI system, microporous filter, water point.

Different raw water treatment processes have different water treatment processes:

For example, reverse osmosis processes are often applied to pure water, purified water, purified water, etc.

Ion exchange technology: It is definitely necessary to apply in the preparation process of demineralized water.

EDI technology is applied to the preparation of ultrapure water, high-purity water, etc.

Reclaimed water reuse technology: It is applied to the treatment project of water reuse.

Precipitation. Flocculation and other technologies: generally applied to wastewater treatment processes.

Inspect and test the wastewater treatment equipment of the epidemic prevention center.

Wastewater treatment process: physicochemical treatment, biochemical treatment, ion exchange, membrane treatment, electrocoagulation, etc.

Oxidation ditch process, A B process, A * A O process, Carousel process, etc.

The amount of sewage in the community is generally not large, and the buried integrated equipment is mostly used, which does not occupy land, and the effluent is used for greening, toilet flushing, car washing, etc.; The landscape water and artificial lake in the park depend on the size of the water volume, and if the water volume is small, it can be filtered and disinfected.

Landscape water treatment generally refers to the community water system, park waterscape, artificial lake, etc., and the main application methods include drug splashing, biodegradation, equipment purification, etc. It takes 1-2 months to spray the drug, which has a certain impact on the ecology and fish. Biological Control Methods:

Regularly put in a reasonable distribution of fish, algae, insects, etc., need to be followed up and guided by professionals at all times. Nowadays, equipment purification is widely used, and filtration equipment is installed next to the landscape water system, which is relatively stable without manual intervention and does not require technology. The following will introduce you to the Jinchi landscape water treatment equipment:

The working principle of Jinchi landscape water treatment equipment. 1.Physical Filtration System - Blocking the physical magazine in the water body, so that the silt, fish feces, organic matter, etc. naturally stay on the filter material.

2.Biochemical filtration system - cultivate rich biological communities, and achieve high water purification effect by surviving tens of billions of colonies such as nitrifying bacteria, photosynthetic bacteria, and water purification bacteria. 3.

Sterilization and algae removal system - remove the growth of microalgae in the water body, solve the problem of fish pond algae more water green, brown, gray, keep the water quality crystal clear, so as to bring a good environment to the fish and organisms in the water body. 4.Water circulation system - the water body circulates 20-40 times a day, compared with the general pumping station and filtration method that only circulates once a few days, the water flow speed is dozens of times faster, and it truly "brings the water to life".

The water also solves the usual aeration problem in the flow, making the fish more cheerful. Scope of application: community water system, courtyard landscape fish pond, park fish pond, rockery landscape, artificial lake, koi fish pond, etc.

The natural world is a very complex system. In order to create such a long-term clear and natural water landscape, a more scientific approach should adopt a comprehensive design and management approach--- that is, NARS (Natural Aquascape Restoration System). With the NARS Natural Water Feature System, you can create a clear, beautiful and vivid natural water feature.

The treatment of NARS mainly includes the following subsystems: NARS sediment management, NARS water quality management, NARS microbial flora, NARS aquatic animal and plant systems, and other measures (such as water quality changes caused by mutation events, etc.).

Innovations or technical features of the NARS natural waterscape system.

Compared with the traditional water control method, the innovations of the NARS natural waterscape system are:

1.NARS focuses on the early treatment of the root cause, while the traditional water treatment method focuses on the later treatment of the symptoms.

2.Teaching the law to create and change, comprehensive management, good governance effect, can be clear;

3.No need to change water, rainwater utilization, save water resources; Routine maintenance costs are low;

4.The original ecological design makes the waterfront, water surface, water and underwater landscape vivid and beautiful.

The NARS waterscape landscape effect --- long-term clear, beautiful and vivid.

1.Cure the root cause --- clear water: the use of NARS technology to treat the substrate and water quality can make the water body clear and natural;

2.Symptomatic --- water beauty: In order to reflect the ornamentality, plant some aquatic animals and plants such as fish, shrimp and aquatic plants to create a vivid and beautiful waterfront, water surface, water and underwater landscape;

3.Low maintenance ---: NARS systems can maintain long-term water quality, clear and beautiful, and low maintenance costs.
