[0042] like Figure 1-11As shown, this embodiment provides a recyclable and quick-disassembly sewage treatment equipment, including an integrated integrated pump station 1 (also known as an integrated pump, an integrated lifting pump station), an anaerobic tank 3, an anoxic tank 4, an aerobic tank 5 and a membrane tank 6 (also known as an MBR membrane tank 6), and the integrated integrated pump station 1, the anaerobic tank 3, the anoxic tank 4, the aerobic tank 5, and the membrane tank 6 are connected in sequence. The anaerobic tank 3, the anoxic tank 4, the aerobic tank 5 and the membrane tank 6 all adopt an enameled assembled tank body. The enameled assembled tank body includes an enameled steel plate 101 and a self-locking bolt 102. A plurality of enameled steel plates 101 are assembled into a tank body, and the ends of adjacent enameled steel plates 101 are overlapped and fixed by self-locking bolts 102. The enameled steel plate 101 includes a titanium alloy steel plate, an enamel layer and a sealant 103; the enamel layer is heated and polymerized on the inner and outer sides of the titanium alloy steel plate, and 2-3 layers of enamel layer are arranged on one side; the sealant 103 is applied to the overlap of adjacent enameled steel plates 101 and the gap between the self-locking bolts 102 and the enameled steel plates 101. In this way, it can be ensured that no liquid leakage occurs. The anaerobic tank 3, the anoxic tank 4, the aerobic tank 5, and the membrane tank 6 are all installed on the concrete structure foundation. Two aerobic tanks 5 are used in this embodiment.

[0043] The anaerobic tank 3, the anoxic tank 4, the aerobic tank 5 and the membrane tank 6 all use enamel assembled tanks, which have the following advantages:

[0044] 1. Beautiful appearance

[0045] It is mainly composed of enameled steel plate 101 (also called enameled assembled steel plate), self-locking bolts 102 and sealant 103, etc. The main component is the enameled assembled steel plate. The enameled assembled steel plate is formed by high-temperature polymerization after double-sided enameled steel plate (referring to titanium alloy special steel plate, i.e. titanium alloy steel plate) is coated with enamel coating. The surface of the enamel layer is smooth and moist, with the characteristics of porcelain. The standard color is green, which is bright and beautiful, especially suitable for the requirements of modern factory construction; any other color can also be used according to the requirements of users.

[0046] 2. Stable quality and strong corrosion resistance

[0047] Enamel steel plate 101 is completely processed and produced in the factory, with a high degree of standardization. It must undergo a series of inspections before leaving the factory, and has stable quality. The special enamel steel plate uses a titanium alloy special steel plate with a thickness of up to 12mm. 2-3 layers of enamel coating are applied on the inner and outer surfaces of the special alloy steel plate, and the coating thickness reaches 300μm. After heating and polymerization, a strong bonding force is formed between the enamel layer and the steel plate. The protective layer formed by the enamel layer can not only prevent the corrosion of the tank body, but also has the characteristics of strong acid, strong alkali and high temperature resistance.

[0048] 3. Short installation period

[0049] The enameled steel plates are manufactured and processed in the factory using standardized production. After packaging, they are transported to the construction site for assembly. The steel plates are connected completely with self-locking bolts 102, making the installation very simple. The installation process is less affected by the weather, and the installation cycle is easy to control.

[0050] 4. Simple installation and maintenance

[0051] The worker installs the top plate of the tank on the ground, then lifts it up to the height of one layer of plate, and then installs the second circle of plates, repeating the operation until the tank is installed. From beginning to end, the worker only needs to stand on the ground to operate, which is simple and safe. The superior anti-corrosion performance of enameled steel plate 101 ensures that the maintenance of the enameled assembled tank is very simple.

[0052] 5. Scalable migration

[0053] The enameled assembled tank body is made of standardized enameled steel plates 101 spliced ​​together with self-locking bolts 102. The tank body can be dismantled or reassembled after it is built and put into operation, and the capacity expansion and relocation of the tank body can be easily achieved.

[0054] The main physical properties of enamel assembly filling are as follows:

[0055] Coating color: Standard color is dark green, or as per user's requirements.

[0056] Coating thickness: 0.25-0.45mm, double-sided coating.

[0057] Acid and alkali resistance: The applicable pH value of the standard coating is: 3-11.

[0058] The applicable pH value of special coating is: 1-14.

[0059] Adhesion: 3,450N / cm.

[0060] Elasticity: Same as the coated steel plate, about 500KN / mm.

[0061] Hardness: 6.0 (using Mohs hardness tester).

[0062] Service life: ≥30 years.

The sewage lifting pump and the crushing device are arranged in the FRP cylinder, and the crushing device is connected to the sewage lifting pump process. The integrated pump station 1 is installed on a concrete structure foundation. The integrated pump station 1 is formed by integrating the sewage lifting pump, the sewage lifting well and the crusher. The FRP cylinder is used as the well wall of the sewage lifting well. The crusher is installed at the water inlet. The larger solids in the sewage are crushed by the crusher, and the slag is mixed in the sewage and enters the sewage lifting well (i.e., the FRP cylinder). It is lifted to the hydraulic curved screen 2 under the action of the sewage lifting pump. A lifting ring is provided on the top of the FRP cylinder to facilitate overall lifting. Correspondingly, escalators, pipelines, valves, maintenance platforms and control systems are provided.

[0064] Taking the actual land area into consideration, the pretreatment unit and the lifting unit are designed as an integrated equipment, that is, the crusher and the lifting pump pool are integrated into one. The layout design is compact and practical, the construction and installation are fast, and the operation, maintenance and management are convenient, thus achieving an overall beautiful and practical effect.

[0065] In order to ensure the use environment requirements of the pump station in sewage, the integrated pump station 1 in this design is made of epoxy vinyl resin inside and outside the pump station cylinder. The equipment integration can be carried out simultaneously with the on-site civil foundation construction. After the strength of the concrete structure foundation reaches the requirements, the integrated pump station 1 can be immediately fixed to the concrete structure foundation, and then the earthwork backfilling work can be carried out. The construction period is significantly shorter than the traditional design, the requirements for on-site construction conditions are low, and the later maintenance is simple and saves land.

A dehydrator 110 is provided in the dehydration workshop 11. The mixed liquid transported from the pump room 8 is dehydrated in the dehydration workshop 11. The sludge separated after dehydration by the dehydrator 110 is transported to the sludge plant. The discharge of the sludge is beneficial to the sludge age control of the sludge and the effect of removing total phosphorus. The water separated by the dehydrator 110 can be sent back to the integrated integrated pump station 1 through a pipeline. At least four dosing pumps 111 are arranged in the dosing workshop 12.
