Description

Technical Field

[0001] The utility model belongs to the technical field of tap water production, and in particular relates to a muddy water treatment facility in the process of tap water production. Background Art

[0002] During the tap water production process, the sediment separated and deposited in the sedimentation tank gathers at the bottom of the sedimentation tank. To ensure the water quality of the sedimentation tank, the bottom sediment needs to be regularly cleaned and discharged. Since the discharged mud water pollutes the environment to a certain extent and wastes some water resources, in order to achieve energy conservation and emission reduction and protect the environment, the discharged mud water needs to be treated.

[0003] At present, the tap water sludge water treatment usually adopts the method of building sludge pool, concentration pool, balance pool and pump room separately, and the pools are connected by pipes. However, according to the running tap water sludge water treatment facilities, it is found that tap water sludge water is mainly inorganic and has a large sand content. During the transportation between the process units, the sludge often blocks the pipes, which greatly increases the maintenance workload, increases the operating cost, and increases the difficulty of management. Utility Model Content

[0004] In view of the problems existing in the prior art, the technical problem to be solved by the utility model is to provide a mud water treatment facility, which can shorten the transportation distance of mud water treatment between pools, reduce blockage, reduce maintenance and repair costs, and reduce floor space.

[0005] The technical problem to be solved by the utility model is achieved through such a technical scheme, which includes a water inlet distribution area, a concentration tank, a sedimentation tank, a water outlet area, a balancing tank and a sludge pump room. The water inlet distribution area and the concentration tank are arranged in two rows in sequence and symmetrically on the left and right sides of the sludge pump room. Behind the sludge pump room, there are also balancing tanks and mud discharge troughs arranged in two rows in sequence. The rear parts of the two concentration tanks are respectively connected to a sedimentation tank, and the rear parts of the two sedimentation tanks are connected to the water outlet area together. The adjacent tank bodies are separated by a partition wall, and the partition wall has an opening for water flow or mud flow to pass through.

[0006] The technical effects of the utility model are:

[0007] The water inlet distribution area, concentration tank, sedimentation tank, water outlet area, balance tank, and sludge pump room are centrally arranged to shorten the transportation distance of mud and water treatment between tanks, effectively reduce the occurrence of blockage, and reduce maintenance and repair costs. Water holes or mud holes are set between each partition wall according to the direction of water flow and mud flow, where the water holes are arranged on the upper part of the partition wall and the mud holes are arranged on the bottom of the partition wall. This arrangement greatly reduces the sludge pipes and sewage pipes between multiple tanks and reduces the floor space. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0012] In order to clearly describe the content of the utility model, this patent application uses the directional words "front", "rear", "left", and "right" for distinction. The "front", "rear", "left", and "right" are determined based on the layout of the above drawings. When the actual use direction of the utility model changes, the directional designation changes accordingly, which cannot be regarded as a limitation on the scope of patent protection. The "front" refers to the muddy water inflow end, and the "rear" refers to the treated water outflow end.

[0013] like Figure 1 As shown, the utility model includes a water inlet distribution area 2, a concentration tank 3, a sedimentation tank 4, a water outlet area 5, a balancing tank 8 and a sludge pump room 9. The water inlet distribution area 2 and the concentration tank 3 are arranged in two rows in sequence and symmetrically arranged on the left and right sides of the sludge pump room 9. Behind the sludge pump room 9, there are also balancing tanks 8 (the balancing tank 8 is used to balance the mud concentration) and a mud discharge trough 12 arranged in two rows in sequence. The rear parts of the two concentration tanks 3 are respectively connected to the sedimentation tank 4, and the rear parts of the two sedimentation tanks 4 are connected to the water outlet area 5 together. The adjacent tank bodies are separated by a partition wall, and the partition wall has an opening for water flow or mud flow to pass through.

[0014] The mud discharge pipe 1 of the water plant sedimentation tank is connected to two water inlet distribution areas 2. The mud and water in the water inlet distribution area 2 enter the concentration tank 3 through the opening of the partition wall. The water holes on the upper part of the partition wall of the concentration tank 3 are connected to the sedimentation tank 4, and the water holes on the upper part of the partition wall of the sedimentation tank 4 are connected to the water outlet area 5; the water outlet area 5 is connected to the return water pipe 6 and the overflow drainage pipe 7; a mud scraper is arranged in the sedimentation tank 4, and the partition wall at the bottom of the sedimentation tank 4 is connected to the lower part of the concentration tank 3 through a mud hole, and the bottom of the sedimentation tank 4 is connected to the mud discharge trough 12 near the central area, and the partition wall between the mud discharge trough 12 and the concentration tank 3 is connected through a mud hole; the bottom partition wall between the concentration tank 3 and the balancing tank 8 is connected through a mud hole; the bottom partition wall between the left and right balancing tanks 8 and the sludge pump room 9 is connected through a mud hole, and the sludge pump room 9 is equipped with a sludge pump output pipe 10 for sending sludge to the dewatering machine.

[0015] exist Figure 1 In the concentrator tank 3, a concentrator truss 11 is installed.

[0016] The operation process of the utility model is:

[0017] The sludge water pipe 1 of the water plant sedimentation tank inputs the sludge water to the water inlet distribution area 2, and then enters the sedimentation tank 4 through the concentration tank 3. The concentration tank 3 is divided into two parts: the sedimented sludge with higher density is concentrated at the bottom of the tank, and the newly entered sludge water with lower density is in the upper part of the tank. The sludge water in the upper part of the concentration tank flows into the sedimentation tank 4 along the water hole on the upper part of the partition wall. The sedimentation tank 4 is equipped with a sludge scraper. The sludge water here is fully precipitated, and the relatively clear supernatant flows into the water outlet area 5. After mixing with the raw water through the return water pipe 6, it is reused again to save water resources. The sludge scraper at the bottom of the sedimentation tank 4 scrapes and flows back through the sludge hole into the concentration tank 3. After concentration, it enters the balance tank 8, and finally passes through the sludge pump room 9 and is pumped out to the desludge machine. When the sludge water treatment facility is abnormal, the sludge water can be urgently discharged to the municipal sewage network through the overflow drain pipe 7 to avoid slurry overflow in the sludge water treatment facility and endanger the safety of related electromechanical equipment.

[0018] The utility model has a centralized arrangement of the water inlet distribution area 2, the concentration tank 3, the sedimentation tank 4, the water outlet area 5, the balancing tank 8, and the sludge pump room 9, which shortens the transportation distance of the sludge and water treatment between the tank bodies, effectively reduces the occurrence of blockage, and reduces the maintenance and repair costs. Water holes or mud holes are respectively set between the partition walls according to the water flow direction and the mud flow direction, wherein the water holes are arranged on the upper part of the partition wall, and the mud holes are arranged on the bottom of the partition wall. This arrangement greatly reduces the sludge and sewage pipes between multiple tank bodies and reduces the floor space.
