Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ecological purification, in particular to a river ecological filtering structure. BACKGROUND

[0002] With the rapid development of national economy, the rapid growth of population and the acceleration of industrialization and urbanization, a large amount of industrial wastewater, domestic sewage and the like is discharged into rivers, lakes and seas without treatment or substandard treatment, resulting in pollution of many rivers to varying degrees. In order to control river pollution, there are various ways: physical method: including but not limited to salvaging floating objects, filtering; chemical method: using chemical agents to purify water areas; biological method: using water organisms, microorganisms, natural sand and stone to form a natural filter layer to purify water areas. The biological method is widely promoted because it does not cause secondary pollution to the environment.

[0003] There are many common biological purification methods. For example, the patent document with publication number CN 212731349 U discloses an ecological filtering system based on pollution river treatment, which directly sets a bearing frame in the river. This method directly intercepts the river, which not only affects the navigation operation of the river and the migration of aquatic organisms (fish), but also easily causes the filter screen to crack due to the interception of excessive debris. There is also a method of laying a floating layer on the water surface and cultivating aquatic plants on the floating layer to absorb pollutants in the river water through the aquatic plants. This method passively adsorbs through plants, has a small purification area and low efficiency, and needs a long time.

[0004] Therefore, the present application provides a river ecological filtering structure which does not affect the normal navigation flow of the river and improves the purification efficiency of the river. CONTENT OF THE INVENTION

[0016] Compared with the prior art, the river ecological filtering structure has the following beneficial effects:

[0017] 1. During use, the floating material filtering barrel forms a negative pressure through water pump suction, thereby sucking river water, and the river surface floating material is driven to fall into the floating material filtering barrel and is intercepted by the filter screen. Thus, large-volume impurities in the sucked river water are filtered, and the river water is preliminarily filtered. Then, the river water enters the S-shaped channel of the filter tank, first experiences adsorption by the left aquatic plants, interception of small impurities by the sand layer, decomposition of organic matter in the water by the metabolic activity of microorganisms in the microbial purification layer, and then passes through the pebble supporting layer to enter the microbial purification layer on the right side of the channel for secondary metabolic decomposition of organic matter by microorganisms and secondary interception of biological small impurities by the sand layer. Then, the water enters the right end water collecting chamber and is discharged into the river channel again from the water outlet pipe. The water is twice purified to achieve the purpose of filtering and grading, and the filtering effect is greatly improved. Moreover, the river water is actively sucked, the purification and filtering amount of the river water is greatly increased, and the efficiency of river water purification and filtering is improved.

[0018] 2. The filter tank floats on the river surface, does not need to cross the river channel, and thus does not affect navigation and biological migration, and also avoids the problem of equipment load capacity increase and collapse that may be caused by crossing the river channel.

[0019] 3. The filter tank bottom wall is provided with a disc-shaped aeration pipe, external air is sucked by the air pump and forms fine bubbles after aeration through the aeration pipe, which can supply oxygen to the microorganisms in the microbial purification layer and the aquatic plants planted in the sand layer, and can also use the fine bubbles to adsorb impurities and float up, thereby improving the purification effect.

[0030] Details of the principles of the present embodiment:

[0031] A river ecological filtering structure, comprising a closed filter tank 1, the upper end of the top wall of the filter tank 1 is detachable, facilitating the installation and maintenance of internal facilities. The filter tank 1 is fixed with a guide plate one and a guide plate two at the bottom wall. The filter tank 1 is fixed with a guide plate three between the guide plate one and the guide plate two. The guide plate one and the left side space of the filter tank 1 form a water distribution chamber 3. The guide plate two and the right side space of the filter tank 1 form a water collecting chamber 4. The water distribution chamber 3 and the water collecting chamber 4 are respectively connected with a water inlet pipe 14 and a drain pipe 13 through a water pump 12. The water inlet pipe 14 is connected with a floating object filtering barrel 2 at the water inlet port, which is used to filter larger floating objects such as branches, leaves, plastic bags, etc.

[0032] The guide plate one, the guide plate two and the guide plate three form an S-shaped channel 5 in the space between the water distribution chamber 3 and the water collecting chamber 4 in the filter tank 1. The channel 5 is laid with a pebble support layer 6, a microbial purification layer 7 and a sand layer 8 from bottom to top. The microbial purification layer 7 provides a living incubator for purifying microorganisms. The sand layer 8 is planted with water-grown plants such as water tanks. The top wall of the filter tank 1 is transparent and translucent, providing light conditions for the plants in the water.

[0033] In use, the filter tank 1 floats on the river surface, and the upper port of the floating object filtering barrel 2 is level with the river surface. The water pump 12 of the water inlet pipe 14 is used to form a negative pressure in the floating object filtering barrel 2, thereby sucking river water and causing the floating objects on the river surface to fall into the floating object filtering barrel 2 and be trapped. Thus, the large-volume impurities in the sucked river water are filtered, achieving preliminary filtration of the river water.

[0034] The preliminarily filtered river water is pumped into the water distribution chamber 3 by the water pump 12 and floats in the water distribution chamber 3, and then enters the water inlet of the S-shaped channel 5. After the river water enters the channel 5, it first undergoes adsorption by the aquatic plants on the left side, is trapped by the sand layer 8, and is decomposed by the metabolic activity of microorganisms in the microbial purification layer 7. Then, the river water passes through the pebble support layer 6 and enters the microbial purification layer 7 on the right side of the channel 5 for secondary metabolic decomposition of organic matter by microorganisms and secondary trapping of biological impurities by the sand layer 8. After that, the river water enters the water collecting chamber 4 at the right end and is discharged into the river channel again from the drain pipe 13.

[0035] Through the above device, first, large sundries are intercepted by the floating matter, and then, fine sundries are intercepted by the secondary sand layer 8 in the channel 5, and the organic matters in the water are decomposed by the metabolic activity of the microorganisms in the microbial purification layer 7, and finally, the water is discharged to the outside, so that the filtering and grading purposes are achieved, and the filtering effect is greatly improved. Moreover, the river water is actively pumped by the water pump 12, so that the filtering and purifying amount of the river water is greatly increased, and the filtering and purifying efficiency of the river water is improved. The filter tank 1 floats on the river surface, does not need to cross the river, and thus does not affect navigation and biological migration, and also avoids the problem that the equipment load capacity is increased and the equipment is collapsed when crossing the river.

[0036] In the embodiment, the bottom wall of the filter tank 1 is paved with a disc-shaped aeration pipe 10, and the aeration pipe 10 is communicated with a gas pump 11 installed on the top wall of the filter tank 1. The gas pump 11 sucks the external gas and forms fine bubbles after aeration through the aeration pipe 10, so as to supply oxygen for the microorganisms in the microbial purification layer 7 and the aquatic plants planted on the sand layer 8, and the fine bubbles can be used to adsorb sundries and float up, so as to improve the purifying effect.

[0037] In a further embodiment of the present scheme, a specific structure of the floating matter filtering barrel 2 capable of intercepting floating matter is provided: the floating matter filtering barrel 2 comprises an outer barrel body 201 installed on the side wall of the filter tank 1, the lower end of the outer barrel body 201 is communicated with the water inlet pipe 14, and a lifting ring 202 is detachably installed on the upper end of the outer barrel body, and a filter screen 203 is installed on the inner wall of the lifting ring 202.

The cross section of the outer barrel body 201 is large at the top and small at the bottom, and sinks into the river surface. The lower end of the outer barrel body 201 is communicated with the water inlet pipe 14, and the lifting ring 202 is detachably installed on the upper end of the outer barrel body, and the filter screen 203 is installed on the inner wall of the lifting ring 202.

When the filter screen 203 is full, the lifting ring 202 is removed, and then the sundries in the filter screen 203 are poured out.

[0041] In a further embodiment of the present scheme, the lifting ring 202 is higher than the upper end surface of the outer barrel body 201, and the outer extension part of the lifting ring 202 is annularly arrayed with a plurality of openings, and the openings are located above the filter screen 203.

[0044] In a further embodiment of the present scheme, the distribution chamber 3 and the water collecting chamber 4 are both filled with sand. That is, the sand layer 8 can first filter the river water, reducing the pressure of the purification filler in the channel 5, avoiding the river water being directly pumped into the distribution chamber 3 by the water pump 12 to form a larger impact, and reducing the impact by sand, and avoiding the sand layer 8 in the channel 5 from being washed away.

[0045] In a further embodiment of the present scheme, the water inlet pipe 14 and the water outlet pipe 13 are close to the bottom wall of the filter tank 1, and the inlet and outlet of the channel 5 are close to the top wall of the filter tank 1, increasing the formation of water inlet and outlet, and further releasing water pressure.

[0046] In a further embodiment of the present scheme, the water inlet pipe 14 extends into one end of the distribution chamber 3, the water outlet pipe 13 extends into both ends, and the air inlet of the air pump 11 is provided with a mesh cover. Through the mesh cover, the filler in the filter tank 1 is prevented from seeping into the water outlet pipe 13 and the water inlet pipe 14, and the debris in the river water is also prevented from entering the water outlet pipe 13.

[0048] In a further embodiment of the present scheme, the filter tank 1 is provided with a mounting rack 15 around the periphery, and the mounting rack 15 is uniformly provided with a plurality of mounting grooves. The mounting rack 15 is used for cultivating wetland aquatic plants. By utilizing the absorption of traditional aquatic plants, the purification range and overall purification efficiency of the device are increased. At the same time, the existence of the mounting rack 15 can provide auxiliary buoyancy for the filter tank 1, and make the filter tank 1 float more stably, reducing the risk of tilting.

[0049] In a further embodiment of the present scheme, the upper end surface of the filter tank 1 is provided with a photovoltaic module 16, the photovoltaic module 16 is connected with a storage battery through an inverter, a photovoltaic sensor and other components, forming a complete photovoltaic power generation and storage system, and being used for supplying power to the air pump 11 and the water pump 12.
