Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a wastewater filtration and separation treatment system. Background Technology

[0002] The production of phosphoric acid generates a large amount of industrial wastewater. To protect the environment and conserve resources, this wastewater typically requires treatment, after which it can be used as fire-fighting water. However, existing wastewater treatment systems cannot effectively remove impurities, calcium, magnesium, inorganic salts, and microorganisms from the wastewater. These substances adhere to the fire-fighting water tanks over long-term circulation, deteriorating the water quality and causing severe scaling on pipes and equipment. This scaling leads to pipe blockage and equipment corrosion. Current methods involve frequent cleaning of the fire-fighting water tanks, but this requires system shutdown. Furthermore, the tanks are often located at high altitudes and have large volumes, making cleaning time-consuming and difficult, significantly impacting subsequent production. Therefore, this application provides a wastewater filtration and separation treatment system to address these problems. Summary of the Invention

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The deterioration of fire water in fire water tanks leads to severe scaling in pipes and equipment. This scaling can cause blockages in pipes and corrosion of equipment. The current solution is to clean the fire water tanks regularly, but this requires shutting down the equipment. In addition, fire water tanks are located at high altitudes and have large volumes, making cleaning a long process and difficult, which greatly affects subsequent production.

[0026] Based on this, this application provides a wastewater filtration and separation treatment system that can effectively treat impurities, calcium, magnesium, inorganic salts and microorganisms in wastewater, avoid the generation of dirt on pipes and equipment, reduce the cleaning cycle of fire water tanks, reduce production costs, ensure the quality of fire water, and guarantee normal production operation.

[0027] Please see Figure 1 This application provides a wastewater filtration and separation treatment system, including: a filter assembly, a treatment water tank 9, a baffle assembly, a first water pump assembly, and a second water pump assembly; the baffle assembly is disposed in the treatment water tank 9, and the baffle assembly is used to divide the treatment water tank 9 into an intermediate water tank and a reclaimed water tank; an inlet pipe 21 is provided on the intermediate water tank, and the filter assembly is provided on the inlet pipe 21; the filter assembly is used to filter external water and allow it to flow into the intermediate water tank; the first water pump assembly is installed on the reclaimed water tank, and the first water pump assembly is connected to an outdoor fire water tank 1; the first water pump assembly is used to discharge water from the reclaimed water tank into the outdoor fire water tank 1; the second water pump assembly is installed on the reclaimed water tank, and the second water pump assembly is connected to an external mill 20; the second water pump assembly is used to pass water from the intermediate water tank into the external mill 20; a plurality of connecting pipes are installed on the intermediate water tank, and the connecting pipes are connected to a sewage regulating tank 19.

[0028] In this embodiment, the treatment tank 9 is divided into an intermediate tank and a reclaimed water tank by a baffle assembly. It should be noted that the volume of the intermediate tank and the reclaimed water tank is not specifically limited in this application and can be determined according to actual conditions. An inlet pipe 21 is installed at the inlet of the reclaimed water tank, and a filter assembly is installed on the inlet pipe 21. The filter assembly effectively treats impurities, calcium, magnesium, inorganic salts, and microorganisms in the wastewater. The filtered wastewater enters the intermediate tank. Because the intermediate tank has a baffle assembly, in addition to dividing the treatment tank 9, it also increases the residence time of the filtered water in the intermediate tank, allowing impurities in the water to continue to settle and separate. The water in the intermediate tank gradually overflows into the reclaimed water tank, thereby reducing the amount of impurities entering the reclaimed water tank. In order to pump water from the recycled water tank to the fire water tank, a first water pump assembly is installed on one side of the fire water tank. The outlet of the first water pump assembly is connected to the external fire water tank. Under the action of the first water pump assembly, water from the recycled water tank can be pumped to the external fire water tank, so that water in the intermediate water tank can be continuously transported to the recycled water tank, and then pumped from the recycled water tank to the external fire water tank, ensuring the continuity of water flow.

[0029] Due to the baffle assembly, a large amount of sludge settles in the intermediate water tank. This sludge needs to be discharged. Specifically, multiple connecting pipes are installed on the intermediate water tank. It should be noted that the baffle assembly divides the intermediate water tank into multiple zones, meaning the number of zones in the intermediate water tank is the same as the number of connecting pipes. For example, if there are three zones in the intermediate water tank, then three connecting pipes are installed on it. These connecting pipes are installed at the bottom of the intermediate water tank, allowing the sludge settled at the bottom to be discharged into the sludge equalization tank 19.

[0030] Optionally, the baffle assembly includes a first baffle wall 10, a second baffle wall 11, and a third baffle wall 12. The treatment water tank 9 is provided with the first baffle wall 10, the second baffle wall 11, and the third baffle wall 12. The first baffle wall 10 is used to divide the treatment water tank 9 into the intermediate water tank and the reclaimed water tank.

[0031] In this embodiment, the baffle assembly includes a first baffle wall 10, a second baffle wall 11, and a third baffle wall 12. The first baffle wall 10, the second baffle wall 11, and the third baffle wall 12 are equally spaced. The specific spacing between these three baffle walls is not limited in this application and can be set according to actual conditions. Each of the first baffle wall 10, the second baffle wall 11, and the third baffle wall 12 is provided with an overflow port 13. The overflow port 13 on the first baffle wall 10 is located below the first baffle wall 10, the overflow port 13 on the second baffle wall 11 is located in the middle of the second baffle wall 11, and the overflow port 13 on the third baffle wall 12 is located below the third baffle wall 12. Furthermore, the first baffle wall 10 is used to divide the treatment water tank 9 into an intermediate water tank and a reclaimed water tank. The overflow outlet 13 is set in different positions in order to increase the residence time of sewage in the intermediate water tank, so that the sludge in the sewage can settle in the intermediate water tank.

[0032] Under the action of the first baffle wall 10, the second baffle wall 11 and the third baffle wall 12, the intermediate water tank can be divided into three areas, namely the first area, the second area and the third area. The first area is provided with a first connecting pipe 16, the second area is provided with a second connecting pipe 15, and the third area is provided with a third connecting pipe 14. The other ends of the first connecting pipe 16, the second connecting pipe 15 and the third connecting pipe 14 are all connected to the sewage equalization tank 19.

[0033] Specifically, the third baffle wall 12 and one side of the treatment tank 9 combine to form the first region, the third baffle wall 12 and the second baffle wall 11 combine to form the second region, and the second baffle wall 11 and the first baffle wall 10 form the third region. In practical applications, wastewater treated by the filtration components enters the first region through the inlet pipe 21. The overflow port 13 of the third baffle wall 12 in the first region is located at the bottom, so the wastewater entering the first region flows into the second region from the bottom of the third baffle wall 12. The overflow port 13 of the second baffle wall 11 in the second region is located in the middle, so when the wastewater enters the second region, it can stay in the second region for a period of time. During this time, the sludge in the wastewater will settle, and then the wastewater flows into the third region from the middle of the second baffle wall 11. Finally, it flows into the reclaimed water tank from the overflow port 13 of the first baffle wall 10 in the third region. It should be noted that when the filtered wastewater enters the first, second, and third zones, sludge can be settled in each zone. The sludge settled in each zone will enter the sewage equalization tank 19 through the first connecting pipe 16, the second connecting pipe 15, and the third connecting pipe 14.

[0034] Optionally, the filter assembly includes a first filter housing and a second filter housing, the first filter housing and the second filter housing are mounted on the water inlet pipe 21, and the connection between the first filter housing and the second filter housing and the water inlet pipe 21 is sealed.

[0035] In this embodiment, a first filter box and a second filter box are provided on the inlet pipe 21. In practical applications, only the first filter box is normally open, and the second filter box serves as a backup. When the first filter box needs cleaning, the backup box is used to ensure smooth production. The internal structures of the first and second filter boxes are identical. It should be noted that when the first filter box is being cleaned, the second filter box acts as the main filtration component, so that after the first filter box is cleaned, it becomes a backup box. This mutual conversion between the two filter boxes 22 is to filter impurities, calcium, magnesium, inorganic salts, and microorganisms present in the wastewater. The filtered wastewater then flows into the intermediate water tank through the inlet pipe 21.

[0036] The first and second filter boxes are each equipped with a filter box 22, a filter screen 23, and a filter sieve plate 24. The filter sieve plate 24 is installed on the top of the filter box 22, and the filter screen 23 is installed below the filter sieve plate 24. A preset gap is provided between the filter sieve plate 24 and the filter screen 23. The filter screen 23 and the filter sieve plate 24 are detachably installed inside the filter box 22. The connection between the filter box 22 and the water inlet pipe 21 is a detachable connection. The connection is sealed to prevent sewage from leaking out from the connection.

[0037] The first water pump assembly includes a first water pump 3, a second water pump 4, a first connecting water pipe 5, a second connecting water pipe 6, and a combined water pipe 2. One end of the first connecting water pipe 5 and the second connecting water pipe 6 is connected to the recycled water tank, the other end of the first connecting water pipe 5 is connected to the first water pump 3, the other end of the second connecting water pipe 6 is connected to the second water pump 4, the other ends of the first water pump 3 and the second water pump 4 are connected to the combined water pipe 2, and the other end of the combined water pipe 2 is connected to the outdoor fire water tank 1.

[0038] The first connecting water pipe 5 and the second connecting water pipe 6 are equipped with branch pipes 7, which are connected to the third water pump 17. A sampling pipe 8 is installed on the branch pipe 7, and the third water pump 17 is connected to the outdoor fire water tank 1. The sampling pipe 8 is installed to facilitate monitoring whether the fire water quality is up to standard.

[0039] The second water pump assembly includes a fourth water pump 18 and a third connecting water pipe. The third connecting water pipe is connected to the intermediate water tank, and the other end of the third connecting water pipe is connected to the fourth water pump 18. The fourth water pump 18 is connected to the external mill 20. The fourth water pump 18 is used to pump water from the intermediate water tank to the external mill 20 to provide a water source for the external mill 20.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application.
