Description

Water purification system

This creation relates to a water purification system, in particular to an intermittent aeration water purification system containing aquatic plants.

According to the United Nations Environment Programme, if no water solutions are proposed in 2025, two out of every three people in the world will feel the pressure of water shortage, so it is urgent to develop diversified water resources. Among them, the recycling of water resources is one of the main channels for increasing water resources. Accordingly, the purification of recycled water resources is an urgent development goal. In order to reduce the impact on the environment and meet the concept of sustainable development, the ecological treatment system (Ecological Treatment System) water recycling method was proposed.

The removal mechanism of pollutants in the ecological treatment system mainly includes sedimentation, adsorption, filtration, nitrification, denitrification, plant absorption and biotransformation. Although the ecological treatment system can effectively remove pollutants in water, the various treatment mechanisms in the ecological treatment system have different decontamination effects in different polluted environments, so it is difficult to make the ecological treatment system applicable to various polluted environments.

In general, when pollutants enter the ecological treatment system, the ecological treatment system mainly removes organic pollutants by oxygenation, and nitrogenous pollution The main removal mechanism of the substance is to convert the nitrogen of the nitrogenous pollutants in the sewage into nitrogen by means of a mechanism such as ammonia gasification (Volatilization), nitrification and denitrification. However, when nitrification is incomplete, denitrification does not completely convert nitrogen-containing contaminants in the water to nitrogen. Therefore, in order to ensure that the nitrification is fully effective, the amount of dissolved oxygen in the water must be higher than the limiting concentration. Among them, although the amount of dissolved oxygen in the water can be increased by adding an aeration device, the jet bubbles generated by the aeration device disturb the flow field in the treatment tank and reduce the removal efficiency of the pollutants by the system. In addition, although the above aeration equipment can increase the dissolved oxygen content of the system water environment, high dissolved oxygen can inhibit the denitration, and the nitrogen-containing pollutants in the water are converted into nitrogen, thereby reducing the removal efficiency of the nitrogen-containing pollutants. .

In addition, in the development of aquaculture, the highly toxic ammonia nitrogen of the culture standard is generally converted into non-toxic nitrate nitrogen by nitrification. However, in outdoor farms, high concentrations of nitrate nitrogen contribute to the proliferation of algae, which can easily lead to deterioration of water quality. In order to avoid the proliferation of algae, the general industry is investing in water quality control drugs, but the quality of the breeding standard is degraded, which reduces its economic value.

In view of this, it is not necessary to provide a water purification system to effectively remove contaminants from water and to improve the defects of conventional water purification systems.

Therefore, one aspect of this creation is to provide a water purification system, which is divided into a septic tank divided into an aeration zone, an aquatic plant zone and a filter zone. The water purification system can effectively reduce pollutants such as organic pollution, nutrients and/or suspended solids in the water.

According to one aspect of this creation, a water purification system is proposed. The water purification system includes an inlet pipe, a sedimentation tank, a purification tank, an outflow tank, and an outlet pipe. The inlet pipe is configured to input sewage into the sedimentation tank, and the outlet pipe is configured to output treated water from the outflow tank. The purification tank is disposed between the sedimentation tank and the outlet tank, and the purification tank comprises an aeration zone, an aquatic plant zone and a filter material zone, wherein the aquatic plant flora is adjacent and disposed between the aeration zone and the filter zone.

The aeration zone is connected to the sedimentation tank by the inlet pipe, and the filter zone is connected to the outflow channel by the outlet pipe. The two communicating ends of the inflow tube are respectively adjacent to the top of the trough of the precipitating tank and the top of the trough of the purifying tank, and the two communicating ends of the filter material area are respectively adjacent to the bottom of the trough of the purifying tank and the bottom of the trough of the outflow trough.

According to an embodiment of the present invention, the foregoing precipitation tank comprises a heat insulation panel covering the precipitation tank.

According to another embodiment of the present invention, the settling tank comprises a drain pipe, and the drain pipe is disposed at the bottom of the tank of the sedimentation tank.

According to still another embodiment of the present invention, the foregoing precipitation tank includes a liquid level detector.

According to still another embodiment of the present invention, the aeration zone is provided with a rectifying structure, and the rectifying structure is adjacent to the aquatic plant zone.

According to still another embodiment of the present invention, the aeration zone comprises a plurality of contact materials.

According to still another embodiment of the present invention, the aforementioned aquatic plant area comprises a water-saturated plant.

According to still another embodiment of the present invention, the filter media zone comprises a plurality of filter materials.

According to still another embodiment of the present invention, the aforementioned outflow trough comprises at least one diffuser disk.

In turn, the cost of water treatment is reduced.

In some embodiments, the settling tank 110 can be the aforementioned sewage storage tank, and the inlet pipe 100a is a system, component, and/or location that directly and/or indirectly connects the discharged sewage.

The sedimentation tank 110 may include drain pipes 110a and 111, and the drain pipe 110a is disposed at the bottom of the sedimentation tank 110. When the sewage is discharged to the sedimentation tank 110, the suspended solids in the sewage may settle at the bottom of the tank of the sedimentation tank 110. When the suspended solids at the bottom of the tank accumulate to a predetermined amount, the suspended solids can be discharged through the sludge discharge pipe 110a, and the sewage capacity of the sedimentation tank 110 can be restored to the initial level. In some embodiments, the bottom of the sedimentation tank 110 may include structures and/or devices that facilitate the collection of suspended solids to accelerate suspension.

The water guiding partition 111 is configured to conduct water downward to increase hydraulic efficiency and reduce short-flow phenomenon, thereby increasing precipitation efficiency. In some embodiments, the water deflector 111 can be secured in the settling tank 110 in a suitable manner. It should be noted that the fixed structure of the water guiding partition 111 (for example, the fixing frame) does not hinder the sedimentation of suspended solids in the sewage, nor does it cause a short flow phenomenon. In addition, the depth of the sewage in which the water guiding partition 111 is not admitted to the sewage tank 110 can be adjusted according to the desired precipitation efficiency.

In some embodiments, the precipitation tank 110 may include a heat shield (shown), and the heat shield covers the sedimentation tank 110 to prevent direct sunlight from the sedimentation tank 110, and the sewage temperature may be lowered to avoid sewage. The phenomenon of eutrophication is more serious, which in turn can suppress the foul odor emitted by sewage.

In some embodiments, the precipitation tank 110 may include a liquid level detector, and the liquid level detector may transmit a signal to the valve switch of the inlet pipe 100a to open or close the valve, and may allow or prohibit the sewage. Pumping. Wherein, when the liquid level detected by the liquid level detector is lower than the connection position of the inlet pipe 121a, the liquid level detector can transmit an "on" signal to the valve switch to allow the sewage to pass through the water inlet pipe. 100a is pumped into the sedimentation tank 110; when the liquid level detected by the liquid level detector is not lower than the set maximum liquid level, the liquid level detector can transmit a "off" signal to the valve switch To prohibit the pumping of sewage.

The aeration zone 121 is connected to the sedimentation tank 110 by the aforementioned inlet pipe 121a, and the filter zone 123 is connected to the outflow channel 130 by the outlet pipe 123a. The sewage system flows through the aeration zone 121, the aquatic plant zone 122 and the filter material zone 123 in sequence.

In some embodiments, the aeration zone 121 may comprise a plurality of contact materials of high contact area to aid in the growth of nitrifying bacteria. Next, the aeration zone 121 may be provided with a jet aeration motor to increase the dissolved oxygen efficiency of the aeration zone 121 by raising the contact area of the air with the water by the microbubbles. In this way, the growth of nitrifying bacteria and the increase of dissolved oxygen, the aeration zone 121 is beneficial for nitrification and biooxidation, and can remove nitrogenous nutrients and organic pollutants in the sewage, thereby improving water quality.

In some embodiments, the aeration zone 121 can be provided with a rectifying structure 121b. The rectifying structure 121b is adjacent to the aquatic plant area 122, and the aerated sewage can be smoothly flowed into the aquatic plant area 122 by rectification by the rectifying structure 121b. In other words, the rectifying structure 121b is disposed at a position where the rectified aeration water can be directly flowed into the aquatic plant area 122. In some embodiments, the septic tank 120 can optionally include a rectification zone (not shown). The rectification zone is adjacent and disposed between the aeration zone 121 and the aquatic plant zone 122, and the aforementioned rectifying structure may be disposed in the rectification zone. In some embodiments, the rectifying structure 121b can be a honeycomb porous tube rectifying structure, other suitable rectifying structures, or any combination of such rectifying structures.

In some embodiments, the aeration zone 121 may be provided with a cover 121c, and the cover 121c covers the aeration zone 121, and the direct sunlight may be avoided.

Moreover, the fixed net or the fixing device does not affect the flow of water, so the water flowing through the aquatic plant area 122 can freely flow into the filter material area 123. Preferably, the fixed mesh or fixture does not create a pressure drop across the water flowing therethrough.

In some embodiments, the filter zone 123 may have a porosity of from 35% to 45%. In one embodiment, the filter zone 123 may have a porosity of 41%. In some embodiments, the septic tank 120 may have an average porosity of 85% to 91%. In one embodiment, the porosity of the purge tank 120 can be 88%.

In some embodiments, the length of the filter media zone 123 can be from 10% to 20% based on the length of the purge tank 120 being 100%. In one embodiment, the length of the filter zone 123 may be 16.1% based on the length of the purge tank 120 being 100%.

In some embodiments, the septic tank 120 can be selectively provided with a submersible motor to meet the needs of aeration.

The water filtered through the filter medium region 123 flows into the outflow tank 130 through the outlet pipe 123a. The water flowing into the outflow tank 130 can be further subjected to a post-aeration treatment to adjust the dissolved oxygen amount in the water by aeration to meet the demand for subsequent water. In some embodiments, the outflow channel 130 can include at least one diffuser disk to aerate water in the outflow channel 130. In some embodiments, the outflow channel 130 can optionally include an air compression pump for post aeration treatment.
