Technical Field

[0001] The utility model relates to the technical field of wetland sewage treatment, and more specifically, to a water purification dam with emergency pollution prevention function. Background Art

[0002] Since integrated sewage treatment equipment is mostly used in rural areas or small towns, and due to reasons such as maintenance and operation costs of integrated sewage treatment equipment and a lack of professional operation and maintenance personnel, the equipment is often rarely operated or even not operated; or there are some rural areas that have no sewage treatment facilities or only simple treatment facilities such as septic tanks, and these simple sewage treatment facilities gradually age and lack maintenance over time. In addition, due to historical reasons and the lack of a coordinated drainage system and sewage collection system for a large number of self-built houses in recent years, the construction of the pipeline network is also complicated, making it impossible to achieve the purpose of effective sewage treatment; in addition, many current artificial wetlands have a long construction cycle, a relatively rigid operation mode, lack flexibility, and are insufficient to deal with changes in sewage sources; and when responding to sudden pollution incidents, existing conventional filtration methods have failed to quickly and effectively treat pollutants.

[0003] Therefore, in order to solve the problems existing in the existing rural and small town sewage treatment, such as difficult sewage treatment construction, high operation and maintenance costs, complex pipeline construction, unstable water quality, insufficient flexibility and redundancy processing capacity, and inability to respond to pollution incidents in emergency situations, the present invention provides a water purification dam with emergency pollution prevention, which can be quickly assembled and constructed according to the terrain and can respond in time to sudden pollution situations to achieve the best effect, thereby effectively solving the problems existing in the existing technology.

[0008] The combined filtration and adsorption device is arranged at the water outlet of the stabilization pond and / or between the wetland treatment pool and the stabilization pond; the combined filtration and adsorption device is composed of several units.

[0009] The utility model discloses a plurality of wetland treatment ponds and stabilization pond are connected in series to form a sewage treatment and purification water path to realize effective treatment of sewage, simplify pipe network construction, facilitate operation and maintenance, and a combined filter and adsorption device is arranged at different positions of the sewage treatment and purification water path, which can be quickly assembled, disassembled and replaced with high-efficiency adsorption substrates (such as carbon residue and activated carbon) to meet the purification requirements caused by changes in sewage, such as emergency purification requirements caused by sudden pesticide pollution and grease pollution, and further improve the sewage purification effect and efficiency.

[0010] Preferably, the combined filter and adsorption device comprises:

[0015] In the present application, different filter combinations are arranged at different positions in the purification water path, which can set more suitable filter and adsorption devices for the positions of the purification water path, so as to provide more effective interception in the event of sudden pollution.

[0016] Preferably, the filter unit comprises at least a pair of porous liquid inlet surfaces and porous liquid outlet surfaces opposite to each other, and a filter medium is arranged between the two porous liquid inlet surfaces.

[0017] The liquid inlet surface and the liquid outlet surface are arranged in a porous structure, which can not only ensure the passing efficiency of the water body but also intercept the pollutants, and the filter medium arranged between the liquid inlet surfaces can further filter and adsorb the water body, thereby effectively improving the water treatment effect.

The different pore diameters of the different filter units can filter different sizes of pollutants to ensure effective interception of the pollutants.

[0029] Preferably, along the water flow path, the pore size of the filter units gradually decreases, and at the same time, the matrix particles filled in the units also gradually decrease, enhancing the adsorption effect.

[0030] The gradually decreasing pore size design can realize step-by-step filtering and adsorption, larger particles being intercepted by larger pores at the initial stage of water flow into the filter units, and smaller particles being captured, adsorbed and decomposed in subsequent filtering layers with smaller pore sizes. Through this step-by-step filtering, different types of pollutants in the water flow can be effectively removed, and the sustainability of matrix adsorption can also be effectively ensured.

[0052] Meanwhile, the liquid inlet surface and the liquid outlet surface are arranged as porous structures, which not only can ensure the passing efficiency of the water body but also can adsorb and intercept the pollutants, and in addition, the substrate arranged between the liquid inlet surfaces is used to further treat the water body, effectively improving the filtering effect.

[0053] Preferably, the filter unit 5 is provided with a medium cavity 8, and the top surface is provided with a feeding port. The filter medium is put into the substrate cavity through the feeding port on the top surface, so as to increase the filtering barrier of the filter unit 5 and improve the filtering effect, and as shown in the drawings, the other side surfaces of the filter unit are porous surfaces in addition to the top surface, which is combined with the drawings. Figure 3 Figure 5 As can be seen in the drawings, in the purification waterway, the water body in the wetland treatment pond 1 can enter the filter unit 5 from the bottom, and is filtered longitudinally as the water rises, which prolongs the filtering path and effectively adsorbs and purifies the pollutants, avoiding the pollutants from entering the next-stage wetland treatment pond 1 or the stabilization pond 2.

[0054] Preferably, different substrates can also be arranged in the arranged substrate cavity 8 according to the purification requirements. When selecting the filter adsorption substrate, the characteristics of the water body and the pollutants to be removed need to be considered. For example, for heavy metal pollution, rhyolite and activated carbon can be used; for oil stains in water, limestone and coal residue can be selected; for the case that the ammonia nitrogen, phosphorus and COD content in the sewage are high, zeolite, carbon residue and ceramsite can be selected. By reasonably matching different filter substrates, the efficiency and effect of water quality treatment can be effectively improved to meet the purification requirements.

[0055] Preferably, as shown in the drawings, the filter unit 5 is provided with a medium cavity 8, and the top surface is provided with a feeding port.

The water outlet 4 is arranged near the upper side of the stable pond 2 and is spaced apart from the bottom of the stable pond 2, so that the stable pond 2 can only drain water when the water level is guaranteed.

[0059] In this embodiment, when facing a sudden pollution event, the water outlet is arranged near the upper side of the stable pond 2 and is spaced apart from the bottom of the stable pond 2, which can reserve sufficient reaction time for the response to the sudden pollution event. By quickly installing the filter device in the containing structure 12, it can be ensured that the pollutants can be effectively blocked and the water quality can be quickly restored.

[0060] Preferably, as Figure 2 shown, the containing structure 10 comprises a receiving table with both sides and bottom closed, and the top of the receiving table is provided with an opening; and a water inlet opening horizontally facing the inner side opposite to the position of the water outlet.

[0061] By closing both sides and bottom of the containing structure 10, the water in the stable pond can only enter the filter device from the water inlet opening when the water amount reaches a certain degree, so that the water body is filtered and adsorbed layer by layer through several filter units before flowing out from the water outlet, thereby achieving a better sewage purification treatment effect.

[0062] Preferably, a handle 11 is arranged on the top of the filter unit 5, which is in a U-shaped structure. The handle 11 is arranged on the top of the filter unit 5 to facilitate installation and disassembly, and does not affect the water flow in normal circumstances, so that the handle 11 can play a protective role in emergency. In the embodiment, the handle 11 is optionally designed to be anti-skid, such as being coated with an anti-skid coating, which prevents the handle from slipping during use and has chemical corrosion resistance to adapt to different use environments.

[0063] Preferably, as shown in Figures 2-4 The filter unit 5 of the outlet filter combination includes at least two porous surfaces. The pore diameters of the porous surfaces in the same filter unit are consistent, and the pore diameters of the filter units 5 in the outlet filter combination are different. Different pore diameters can filter different sizes of pollutants to ensure effective interception of pollutants.

[0064] Preferably, as shown in Figure 2 The pore diameters of the filter units 5 arranged on the containing structure 10 gradually decrease along the water flow path, so that different filter units filter and adsorb different pollutants to share the water treatment pressure of different filter units, realize step-by-step filtration, and larger particles are intercepted by larger pores in the early stage of water flow into the filter unit, and smaller particles are captured in subsequent finer pore size filter layers. Through this step-by-step filtration, different sizes of pollutants in the water flow can be effectively removed, and the durability of the adsorption of the filter unit can be maintained.
