Description

Multifunctional water purifying equipment
Technical Field
The present disclosure relates to an apparatus for purifying water, and more particularly, to a water purifying apparatus for treating the quality of a water body.
Background
The water treatment objects mainly comprise natural water bodies and artificial water bodies. Such as river and lake water bodies, garden landscape water bodies, culture water bodies, fountains, swimming pools, water parks and the like. Most of the water bodies have the characteristics of low pollutant concentration, diversified pollution sources, great water quantity and turbidity in rainy days. The urban built-up area has higher requirements on water quality and sanitary conditions, and can continuously generate artificial or non-artificial pollution in the operation process.
For example, river black and odorous is a representative bad fruit and important problem to be solved for urban environmental pollution and ecological destruction in China, and the exceeding of organic indexes such as ammonia nitrogen, total phosphorus and the like is a prominent problem to be solved urgently in many urban black and odorous river channels at present. The main pollution sources of the river water body are the injection of external pollutants and substances released by river bottom sludge accumulated for a long time. In addition, the water body is lack of necessary circulation, the dissolved oxygen is too low, and the living environment of aquatic animals and plants is lacked, so that the water body gradually loses the self-cleaning capability and is easy to blacken and smell. In addition, the injection amount of external pollutants is random, and particularly for areas with more rainwater, rainwater can concentrate to bring more external pollutants, so that the water quality of the river water body is rapidly deteriorated.
As for the current technology for remedying the polluted water body of the river channel, the biological-ecological technology is a more scientific way for remedying the polluted water body. According to the ecological principle, the self-purification capability of aquatic ecological animals and plants and microorganisms is utilized to absorb organic pollutants in the water body, so that the aim of purifying the water quality can be fulfilled.
The current bio-ecological technology is generally built in the forms of artificial wetlands, biological oxidation ponds, biological filter beds and the like. This method requires a large amount of infrastructure construction, which leads to an increase in cost and maintenance, and this water treatment scheme limits the amount and place of treatment and cannot flexibly cope with rapid deterioration of water quality. Furthermore, the existing water treatment devices placed in watercourses and other water bodies cannot be adjusted in real time or adaptively according to the change of the water bodies.

It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

The use of "first," "second," and similar terms in the description and claims of the present disclosure are not intended to indicate any order, quantity, or importance, but rather are used to distinguish one element from another. Also, the use of the terms "a" or "an" and the like do not necessarily denote a limitation of quantity. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
Fig. 1 is a schematic view of a multi-functional water purifying apparatus according to one embodiment of the present disclosure from above. As shown in fig. 1, the multi-functional water purification apparatus may include a first aeration system 2, a second aeration system 5, a water purification system 3, and a microorganism system 4. The multi-functional water purification apparatus may further include a control system (not shown) for controlling the operations of the first aeration system 2, the second aeration system 5, the water purification system 3, the microorganism system 4, and the like. The control system may be implemented using a single or multiple controllers.
The multi-functional water purification apparatus may be carried by a main body 1 (e.g., a ship hull) so that the apparatus floats on the water surface, forming a mobile water treatment system. The mobile water treatment system can also be provided with a steering system for controlling the running direction of the mobile water treatment system, and the steering system can be designed to be operated on site or remotely, so that a worker can conveniently control the mobile water treatment system to realize directional movement on the water surface.
Although the first aeration system 2 and the second aeration system 5 are shown in fig. 1, the present embodiment is not limited to two sets of aeration systems. The number of aeration systems may be determined as desired. The aeration system can aerate and oxygenate the water body and provide power for the equipment to move forwards. Each aeration system can work independently under the control of the control system.
Fig. 2 illustrates a schematic sectional view of an aeration system of a multi-functional water purification apparatus according to an embodiment of the present disclosure. The structure and operation of the first aeration system 2 will now be described with reference to fig. 1 and 2. The first aeration system 2 may include an automatic water intake mechanism 21, an air intake mechanism 22, and a jet mechanism 23. The water flow end of the automatic water taking mechanism 21 is connected with the fluidic mechanism 23, and the upper end of the fluidic mechanism 23 is connected with the air intake mechanism 22.
The automatic water intake mechanism 21 is provided with a grill 211, an inlet channel 212, a water storage chamber 213, a pump 214 (e.g., a wet and dry pump) and an outlet channel 215 in the water flow direction, wherein the wet and dry pump is connected to the outlet of the water storage chamber, and the outlet channel is connected to the outlet of the wet and dry pump. When the automatic water intake mechanism 21 works, water is injected into the water storage cavity 213 until the water level of the water storage cavity 213 reaches the maximum, and then the water filling port is sealed, so that only the water inlet channel 212 is left as the water inlet. The wet and dry pump 214 is then activated to deliver the water within the water storage chamber 213 to the water outlet channel 215 and then into the jet mechanism 23. At this time, the water level of the water storage cavity 213 is gradually decreased to gradually decrease the air pressure in the cavity to form a negative pressure, and the external water is filtered by the grating 211 and gradually rises from the water inlet 212 to the water storage cavity 213. The water outlet channel 215 is designed to be raised (i.e. higher than the water storage chamber 213), so as to facilitate the water storage of the water storage chamber 213. The structure of the automatic water taking mechanism 21 solves the limitation of the wet and dry pump 214 on the water level requirement, and simultaneously reduces the height and draft of the equipment, so that the environmental requirements (the water level requirement of the water body, the height of a bridge on the water surface and the like) of the equipment on the use site are reduced, and the universality is stronger.
The air intake mechanism 22 includes an air intake main pipe 221 having one end connected to a valve 222 and the other end connected to one or more air intake branch pipes 223. The jet mechanism 23 is connected with the air inlet mechanism 22, wherein a spiral part 232 is arranged in an outlet pipe 231 of the jet mechanism 23, so that water in the spiral part is in a spiral circulation mode, and the mixing is more uniform.
During operation in the aeration mode, the valve 222 is opened, and the water body after water is taken by the automatic water taking mechanism 21 passes through the jet mechanism 23. The jet mechanism 23 may create a negative pressure such that air enters through the valve 222 of the air intake mechanism 22 and mixes with the water body in the outlet pipe 231, thereby aerating and oxygenating the water body.
The second aeration system 5 is similar in structure to the first aeration system and may include an automatic water intake mechanism 51, an air intake mechanism 52, and a jet mechanism 53. The water flow end of the automatic water intake mechanism 51 is connected to the jet mechanism 53, and the upper end of the jet mechanism 53 is connected to the air intake mechanism 52. Since the structure of the automatic water intake mechanism of the second aeration system 5 is the same as that of the first aeration system 2, it is not shown repeatedly in fig. 2. The structure and operation of the automatic water intake mechanism of the second aeration system 5 can be referred to the description of the automatic water intake mechanism 21 of the first aeration system 2 above. Fig. 2 schematically shows the air intake mechanism 52 and the jet mechanism 53 of the second aeration system 5.
The intake mechanism 52 includes an intake main 524. The main intake pipe 524 is connected at one end to a valve 525 and at the other end to one or more branch intake pipes 526. The jet mechanism 53 is connected with the air inlet mechanism 52, wherein a plurality of feeding holes 534 are arranged on a water outlet pipe 533 of the jet mechanism 53, and the feeding holes 534 are provided with fillers 535.
In the operation process of the aeration mode, the valve 525 is opened, the water body after the automatic water taking mechanism takes water passes through the jet mechanism 53, the jet mechanism 53 forms negative pressure, so that air enters through the valve 525 of the air inlet mechanism 52, and the air and the water body are mixed in the water outlet pipe 533, thereby aerating and oxygenating the water body.
Valve 222 and valve 525 may be controlled by the control system and opened upon activation of the aeration system. The number of aeration systems can be increased as desired. The first aeration system and the second aeration system can also be used independently, namely, the water purifying device can only comprise the first aeration system or the second aeration system according to the requirement. The control of the first aeration system and the second aeration system will be described in detail below with reference to fig. 4. Valves 222 and 525 may be automatic valves that can be controlled by a control system.
Fig. 3 shows a schematic sectional view of a water purification system of a multipurpose water purification unit according to an embodiment of the present disclosure. The structure and operation of the water purification system will be described with reference to fig. 1-3.
The water purification system 3 may include a water purifying agent passage 31, a brewing water passage 32, a dosing passage 33, and a water purifying agent bucket 34. The water purifying agent passage 31 is a water purifying agent dosing passage, and may include a water purifying agent tank 311 and an adjusting valve 312. The amount of the purifying agent in the purifying agent tank 311 entering the purifying agent tank 34 is controlled by the regulating valve 312. The modulated water passage 32 is a passage for quantitatively adding the water body mixed with the water purifying agent. A water pump 321 in the brew water channel 32 controls the amount of water entering the water purifying agent tank 34. The water purifying agent and the water body are uniformly mixed under the action of a stirrer 35 in the water purifying agent barrel 34. The adding channel 33 quantitatively and uniformly adds the mixed water purifying agent liquid, and may include a metering pump 331, a distributor 332 and a pipeline 333. The adding amount of the mixed water purifying agent liquid can be controlled by a metering pump 331 according to the water quality requirement, the added water purifying agent liquid is uniformly distributed to the air inlet branch pipe 223 of the air inlet mechanism 22 through a distributor 332 and then enters the water outlet pipe 231, so that the water purifying agent liquid and the water body in the water inlet mechanism are uniformly mixed in a swirling flow mode under the action of the spiral part 232 and then are discharged in a jetting manner, and a better water purifying effect is obtained. The jet flow discharge mode stirs nearby water areas, so that the influence range of the water purifying agent liquid is wider, and the actual treated water quantity is larger and more uniform.
Although the water purification system 3 is shown to be connected to the intake branch pipe 223 of the intake mechanism, the water purification system 3 may be connected to other positions of the inlet front end of the jet mechanism. As long as the water purification system 3 is connected to the inside of the negative pressure region at the front end of the inlet of the jet mechanism, the water purifying agent liquid can be sucked into the water outlet pipe 231 by the negative pressure action of the jet mechanism.
According to the structure, the aeration system 2 and the water purification system 3 are used in a mixed mode, and the water purification agent and the water body are improved in the contact influence range by aeration and stirring of the water body. Further, the water purification system 3 discharges the water purifying agent liquid by sharing the jet mechanism 23 with the first aeration system by connecting to the inlet front end of the jet mechanism, for example, the intake branch pipe 223 of the intake mechanism 22. When the water purification system 3 is in operation (i.e. in the purification mode), the valve 222 is closed. Because the jet mechanism 23 forms negative pressure, the water purifying agent liquid is sucked into the water outlet pipe 231 and is thrown into the water body through the action of the negative pressure. Thereby, energy required for adding the water purifying agent liquid is saved and equipment (such as a water pump) required for adding is reduced.
Referring back to fig. 1, the microbial system 4 may include a microbial tank 41, a solenoid valve 42, a distributor 43, and a pipe 44. Microorganisms are stored in the microorganism barrel 41, and the microorganisms can be in the forms of primary microorganism bacteria liquid or microorganism bacteria liquid prepared and cultured by microbial inoculum and nutrient solution, and the like. The microorganism tank 41 is connected with the air inlet branch pipe 526 of the air inlet mechanism 52 of the second aeration system through the distributor 43 and the pipe 44.
Although the figure shows the microbial system 4 connected to the air inlet branch 526 of the air inlet means, the microbial system 4 may be connected to other positions of the inlet front end of the fluidic means. As long as the microorganism system 4 is connected to the negative pressure region at the front end of the inlet of the jet mechanism, the microorganism liquid can be sucked into the water outlet pipe 533 by using the negative pressure effect of the jet mechanism.
As can be seen from the above structure, the microorganism system 4 feeds the microorganism solution by connecting to the inlet front end of the jet mechanism, for example, the air inlet branch pipe 526 of the air inlet mechanism 52, and sharing the jet mechanism 53 with the second aeration system. When the microbial system 4 is operating (i.e., in the microbial dosing mode), the valve 525 is closed. Because the jet mechanism 53 forms negative pressure, the microbial liquid in the microbial system 4 is sucked into the water outlet pipe 533 and flows out from the feeding hole 534, so that the microbial liquid is attached to the filler 535 to grow and reproduce, and is used for degrading organic matters in the water body.
In the device, the second aeration system 5 and the microorganism system 4 are used together, aeration and stirring of the water body improve the contact of the microorganisms and pollutants, and the provided dissolved oxygen (Do) activates the biological activity of the microorganisms. The filler 535 is arranged to provide a colonizing carrier for the microorganism, so that a more suitable growth environment is created for the proliferation, proliferation and growth and inhabitation of the microorganism, the phenomenon that the added microorganism falls into water to form a zoogloea and is rapidly precipitated to the bottom of the tank due to aeration stirring is avoided, and energy required by adding the microorganism liquid is saved.
Fig. 4 shows a schematic diagram of a control flow of a control system of a multipurpose water purification apparatus according to an embodiment of the present disclosure.
The control system includes one or more controllers and may be controlled on-site or remotely. The control system may also include a memory for recording various operational parameters of the plant (including, but not limited to, operational parameters of the aeration system, water purification system, microbial system; operational parameters of the valves and water pumps; detected water quality parameters, etc.) and transmitting them to a control center or data center for real-time monitoring or data analysis.
The control system first acquires data relating to the water quality measured by the water quality analysis sensor (step 401). The water quality analysis sensor 6 may be installed in a multifunctional water purification apparatus, or may be installed in other apparatuses or as a separate detection apparatus. The water quality analysis sensor can detect Chemical Oxygen Demand (COD), ammonia nitrogen content (NH3-N), dissolved oxygen (Do), water turbidity (H), water temperature, PH parameters and the like of the water body to be treated.
