Description

Technical Field

[0001] This utility model relates to an integrated wastewater treatment equipment, and more specifically, an integrated equipment for treating wastewater from chemical industrial parks containing a large amount of ammonia nitrogen and organic matter. Background Technology

[0002] The chemical industry is prevalent worldwide, producing large volumes of wastewater that are difficult to treat. Wastewater treatment needs are widespread in chemical industrial parks, requiring not only the long-term, stable treatment of wastewater generated within a single park but also the on-the-spot handling of occasional pollution. For treating small-scale, sporadic pollution, integrated treatment equipment offers significant advantages due to its rapid response and ease of operation.

[0003] Ammonia nitrogen and various organic compounds are common chemical raw materials and therefore important components of wastewater from chemical industrial parks. Wastewater from chemical industrial parks is unsuitable for biological treatment because it often contains toxic substances, and even if microorganisms can adapt and survive, the treatment efficiency is very low. Chemical methods are more suitable than biological methods. Most of the organic matter in wastewater from chemical industrial parks is recalcitrant and should be treated using advanced oxidation processes, specifically Fenton oxidation and ozone oxidation. Although advanced oxidation processes have strong oxidizing power, their oxidation efficiency for ammonia nitrogen is very limited. Utility Model Content

[0004] To overcome the above-mentioned defects, the purpose of this utility model is to provide an integrated wastewater treatment equipment that uses a combination of ozone oxidation and sodium hypochlorite oxidation to remove organic matter and ammonia nitrogen from wastewater in chemical industrial parks.

[0005] To achieve the above objectives, the present invention provides an integrated wastewater treatment device, comprising:

[0006] The enclosure contains an equipment room and a reaction room;

[0007] The equipment room is equipped with ozone generators, sodium hypochlorite solution storage tanks, and control equipment.

[0008] The reaction chamber is divided into an ozone reaction chamber and a chlorination reaction chamber that are connected end to end by a partition.

[0009] A raw water distribution pipe and an ozone solution distribution pipe are installed at the head of the ozone reaction chamber; a sodium hypochlorite solution distribution pipe is installed at the head of the chlorination reaction chamber; and a drain pipe is installed at the tail of the chlorination reaction chamber.

[0010] The ozone generating equipment includes an ozone generator and an ozone dissolved gas tank. The ozone generated by the ozone generator enters the ozone dissolved gas tank through a pipeline.

[0011] The ozone dissolved gas tank is equipped with an inlet and an outlet. An ozone dissolved gas water pipe is installed at the inlet of the ozone dissolved gas tank to draw clean water from the chlorination reaction chamber near the drain pipe into the ozone dissolved gas tank. The inlet of the ozone dissolved gas water pipe is lower than the drain pipe. The outlet of the ozone dissolved gas tank is connected to the ozone solution distribution pipe through a pipeline.

[0012] The sodium hypochlorite solution distribution pipe is connected to the sodium hypochlorite solution storage tank via a pipeline.

[0013] Furthermore, the raw water distribution pipe is located at the bottom of the ozone reaction chamber.

[0014] Furthermore, the water flow direction in both the ozone reaction chamber and the chlorination reaction chamber is bottom inlet and top outlet.

[0015] Furthermore, the water effluent above the tail of the ozone reaction chamber enters the chlorination reaction chamber from below the head of the chlorination reaction chamber after passing through a pipe or channel.

[0016] This utility model has the following advantages:

[0017] (1) The integrated equipment adopts a combination process of ozone oxidation and sodium hypochlorite oxidation, which can efficiently treat wastewater containing a lot of ammonia nitrogen and organic matter in chemical industrial parks.

[0018] (2) All equipment is integrated into a rectangular box, which is simple and beautiful in appearance and easy to operate.

[0019] (3) After the ozone oxidation process, the sodium hypochlorite oxidation process is carried out. Sodium hypochlorite has the effect of decomposing ozone and reducing exhaust gas pollution. Attached Figure Description

Detailed Implementation

[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1 As shown, an integrated wastewater treatment device comprises two parts: ozone oxidation for removing organic matter and sodium hypochlorite oxidation for removing ammonia nitrogen. All equipment is integrated into a rectangular box, which is divided into three smaller rectangular boxes. Ozone oxidation and sodium hypochlorite oxidation each occupy one box, and supporting facilities are integrated into another box.

[0028] The ozone generator 11 uses an air source to draw in air and generate ozone. The generated ozone enters the ozone dissolved gas tank 12. A water pump draws purified water through the ozone dissolved gas water pipe 13 into the ozone dissolved gas tank. The inlet of the ozone dissolved gas water pipe 13 is lower than the outlet pipe 7, so the ozone is fully dispersed in the water as tiny bubbles in advance to improve the ozone utilization efficiency. Then, it enters the lower part of the ozone reaction chamber 51 through the ozone solution distribution pipe 14. The ozone reaction chamber is filled with an ozone oxidation catalyst.

[0029] Sodium hypochlorite solution is supplied externally and stored in a sodium hypochlorite solution storage tank 31, with a sodium hypochlorite solution inlet 32 ​​at the top. During equipment operation, a metering pump draws sodium hypochlorite solution from the storage tank and adds it to the lower part of the chlorination reaction chamber through a sodium hypochlorite solution distribution pipe 33. The sodium hypochlorite solution storage tank does not necessarily store sodium hypochlorite solution; it can also contain other chlorine substances with oxidizing capabilities, such as chlorine gas solution.

[0030] To facilitate operation by ensuring that the inlets are close together, the raw water inlet 41 is located near the sodium hypochlorite solution storage tank and is introduced into the lower part of the ozone reaction chamber through the raw water distribution pipe.

[0031] Display and control cabinet 2 is placed between the ozone generator and the sodium hypochlorite solution storage tank, at a height of approximately 1.5m. It displays various parameters such as ozone concentration, gas flow rate, and water flow rate; and provides switches for the ozone generator, pumps, and other components controlled via PLC or similar devices.

[0032] Both ozone oxidation and sodium hypochlorite oxidation have a bottom-in, top-out water flow direction. The water from the top of the ozone oxidation chamber passes through a transition chamber composed of two baffles and then enters the chlorination reaction chamber from the bottom. Alternatively, they can be connected by pipes.

[0033] The integrated device of this invention is made of corrosion-resistant stainless steel and is sealed. All necessary connections to the outside world (including material exchange sections such as the sodium hypochlorite solution inlet, and openings such as observation ports and maintenance ports) are ensured to be easily and completely sealed.

[0034] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Many other changes and modifications made without departing from the concept and scope of the present invention should be considered within the protection scope of the present invention.

[0035] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
