Description

Technical Field

[0001] This utility model provides a combined assembled sewage treatment and purification device, belonging to the field of sewage treatment technology. Background Technology

[0002] With the acceleration of urbanization and increasingly stringent environmental protection requirements, the demand for wastewater treatment facilities has experienced explosive growth. Among these, the wastewater treatment process typically involves a biological treatment + membrane separation process: Pretreatment tank: Large particulate impurities are initially removed through screens and grit removal to regulate water quality; Anoxic tank: Anaerobic microorganisms decompose organic matter, releasing phosphorus and creating conditions for subsequent treatment; Aerobic tank: Aerobic microorganisms further degrade organic matter, removing BOD and COD, while simultaneously carrying out nitrification; MBR membrane tank: Combining membrane separation technology, suspended solids and pathogenic microorganisms are removed, ensuring the effluent meets high discharge standards; Storage tank: The treated clean water is stored for reuse or discharge.

[0003] Existing wastewater treatment technologies using biological treatment combined with membrane separation processes can generally meet normal usage needs. However, these typically employ cast-in-place reinforced concrete tanks, which require the construction of pretreatment tanks, anoxic tanks, aerobic tanks, MBR membrane tanks, and water storage tanks. This construction period is often relatively long, making it difficult to meet the needs of emergency response or rapid deployment. Furthermore, once completed, these tanks are often difficult to dismantle, and after a period of use, cracks appearing in the concrete tanks are difficult to repair. Therefore, this invention provides a combined prefabricated wastewater treatment and purification device. Utility Model Content

[0004] The technical problem solved by this utility model is that the construction cycle of cast-in-place reinforced concrete pools is often relatively long, making it difficult to meet the needs of emergency treatment or rapid deployment. After construction, they are often difficult to demolish, and after a period of use, the cracks that appear on the concrete pool are also difficult to repair.

[0005] To solve the technical problem, the technical solution provided by this utility model is: a combined assembled sewage treatment and purification device, comprising: The concrete base slab is poured into the pre-excavated foundation pit; The modular tank body is set on top of a concrete base slab and includes a frame and several partitions set between the inner sidewalls of the frame. The internal space of the tank body is sequentially divided into a pretreatment tank, an anoxic tank, an aerobic tank, an MBR membrane tank, and a water storage tank by the several partitions. The frame and partitions each include several precast slabs. The bottom of each precast slab is provided with a plate that can be inserted into a concrete base slab. A connector is provided between adjacent horizontal precast slabs and a connector is provided between adjacent vertical precast slabs to splice the precast slabs together.

[0006] Furthermore, the side wall of the insert plate is provided with a plurality of grooves from top to bottom, and the connector includes a locking plate fixedly disposed in the groove, and the side wall of the locking plate is provided with an insert rod inserted into the precast plate.

[0007] Furthermore, the bottom of the groove is provided with bolt holes, and the locking plate is fixedly installed in the groove by high-strength bolts screwed into the bolt holes. The side wall of the precast plate is provided with an embedding hole that communicates with the groove and matches the embedding rod.

[0008] Furthermore, the connector also includes a one-line sealing plate, and the edge of the precast slab sidewall is provided with a sealing strip that fits with the one-line sealing plate. The one-line sealing plate is fixedly mounted on the sidewall of the precast slab by high-strength bolts.

[0009] Furthermore, the second connector includes an L-shaped sealing plate, and the edge of the precast slab sidewall is provided with a sealing strip second that fits with the L-shaped sealing plate. The L-shaped sealing plate is fixedly mounted on the sidewall of the precast slab by high-strength bolts.

[0010] Furthermore, the top of the concrete base plate is provided with a slot that matches the insert plate, and the top of the concrete base plate is provided with a barrier placed outside the slot.

[0011] Furthermore, the sum of the height of the enclosure and the depth of the slot is adapted to the height of the insert plate, and the gap between the enclosure and the insert plate is filled with concrete.

[0012] The beneficial effects of this utility model are: The modular pool design effectively shortens the on-site construction period, meets the needs of emergency response or rapid deployment, and facilitates dismantling after completion. It also effectively improves the seepage prevention capacity and allows for convenient inspection and replacement of damaged straight or L-shaped sealing plates, thus facilitating the repair of seepage cracks.

Lifting and positioning of precast slab 10: A crane equipped with special lifting tools is used for lifting. When the first precast slab 10 is in place, the insert plate 11 is aligned with the slot 22, and the slab is slowly lowered vertically. Adjacent precast slabs 10 are lifted in sequence. The locking plate 14 is pushed into the groove 13 on one precast slab 10 and fixed in the groove 13 by high-strength bolts screwed into the bolt holes 16. Another adjacent precast slab is lifted to the side of the locking plate 14 and finely adjusted so that the embedding rod 15 is inserted into the embedding hole 17 on the side wall of the other adjacent precast slab 10 until the joint between adjacent precast slabs 10 is reached. Joint sealing: The joints between adjacent horizontal precast slabs 10 are sealed with a straight sealing plate 18, and the joints between adjacent vertical precast slabs 10 are sealed with an L-shaped sealing plate 21. Grouting and sealing: Concrete is poured into the gap between the insert plate 11 and the enclosure 23; Equipment placement: After assembly, install internal equipment such as fans, water pumps, and membrane modules, and perform electrical wiring for wastewater treatment.
