Description

A kind of rotating disc type filtering ponds
Technical field
The utility model relates to a kind of sewage water depth-type filtration treating apparatus, specifically is meant a kind of rotating disc type filtering ponds.
Background technology
At present in the advanced treatment of wastewater field; mainly adopting tank body pressure filtration and filler not to have ballast power to sewage water filtration filters; its filtrate major part is horizontal distribution; its major defect: suspension is deposited in the surface of filtrate very soon in the water; thereby area of passage is reduced; the choked flow aquaporin; must shut down and carry out backwash, need to build large-scale air blast machine room, and the backwash pump house; and a period of time will be changed filtrate; the operation energy consumption height, manipulation strength is big, and floor space is very big; the civil engineering costs height, unit ton water cost filters high than rotating disc type.
In recent years, in the advanced treatment of wastewater field, the application of rotating disc type filter more and more widely, advantage such as it is good to have a treatment effect, and water quality and quantity is stable, and operation maintenance is simple and convenient.The main distinction is had nothing in common with each other on water intake mode and backwash mode.Interior water intake mode: sewage flows into filter disc inside by central tube, and the gravity effect sees through filter medium down and flows into the filter tank, is discharged by the filter tank effluent weir again.The major defect of interior water intake mode is: enter filter disc inside if any the bulk dirt with water in the sewage, the utmost point is easy to clean not, and can cause plugged filtration media, reduces effective filtration area.The backwash in interior water inlet filter tank can only be by oneself high-pressure spray wash outside to inside.The work liquid level of interior water inlet rotating disk is positioned at the dirt of rotating disk and is accepted the bucket limitation in height, effective filtration area (being inundated area) can only reach about half of the gross area, makes that design dish number is more than the required dish number of outer water inlet form under the equal flow, take up an area of greatlyyer, invest more.Therefore on water intake mode that filters and backwash mode, make rotating disc type filter treatment effect better, operation maintenance is more convenient, has become this area technical problem anxious to be solved.
The utility model content
The purpose of this utility model is to provide a kind of rotating disc type filtering ponds, rationally utilizes the effective area of rotating disk, makes wastewater treatment efficiency better, and the operation maintenance of equipment is more convenient.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rotating disc type filtering ponds, comprise the water inlet distribution well, rotating disk pond, clear water reserviors, the blowoff basin that connect successively, bottom in the rotating disk pond is provided with sludge bucket, center rotary drum, the transmission device that is connected with the center rotary drum are installed in described rotating disk pond and are installed on the rotary drum of center and the rotating disk coaxial with the center rotary drum, surface at rotating disk is provided with filter cloth, is separately installed with aspirator and back purge system in rotary drum both sides, center.Supporting construction and back supporting construction before two ends, rotating disk pond are provided with, the two ends of on preceding supporting construction and back supporting construction, placing the center rotary drum, the center rotary drum rotates in the rotating disk pond by the drive of transmission device, the rotating disk that is installed on the rotary drum of center moves in a circle cleaning and foreign substances that aspirator that is provided with respectively in the both sides of center rotary drum and back purge system circulate to the filter cloth that is installed in disc surfaces with the rotation of center rotary drum in the rotating disk pond.
Between described water inlet distribution well and rotating disk pond, be provided with water inlet, between described rotating disk pond and clear water reserviors, be provided with delivery port, between described clear water reserviors and blowoff basin, be provided with water level and regulate weir gate.
Be provided with into water cloth mill weir at the two ends in described rotating disk pond, be provided with the gate before being positioned at water inlet in the water inlet distribution well, the side of water inlet cloth mill weir is provided with perforation.
Above described delivery port, also be provided with overfall.
The utility model is adjusted current by the setting of water inlet, delivery port, water level adjusting weir gate, water inlet cloth mill weir, overfall, makes current enter each filter tank equably, reduces the influence of current to filter effect.
Described aspirator comprises the rotating disk suction pump that is installed on the rotating disk pond, also comprises the rotating disk aspirator that is connected with the rotating disk suction pump by suction channel, on described suction channel motor-driven valve is installed.By the rotating disk aspirator filter cloth on the rotating disk is aspirated, can effectively aspirate the impurity on the filter cloth.
Described back purge system comprises the backwash water pump that is installed in the clear water reserviors, also comprises the high-pressure wash shower nozzle that is connected with the backwash water pump by flushing pipe, and pulse adjusting device and motor-driven valve are installed on flushing pipe.The backwash water pump utilizes the clear water in the clear water reserviors, after supercharging, the filter cloth on the rotating disk is cleaned, finish cleaning procedure to filter cloth after, filter cloth enters the filtration state.
The water spraying direction of described high-pressure wash shower nozzle is identical with the direction of rotation of rotating disk.
Described the mud suction pump being installed on the rotating disk pond, in the mud suction pump, being connected with the dredging tube that inserts in the sludge bucket, on described dredging tube, motor-driven valve is installed.Because the pressure differential that rotating disk is inside and outside makes water pass through micron-sized filter cloth, suspension is trapped within the filter tank, be deposited in the sludge bucket of bottom, by the mud suction pump mud is aspirated out the filter tank, the water that sees through enters into clear water reserviors by the center rotary drum of hollow, finishes the filtration to sewage.
The utility model compared with prior art has following advantage and beneficial effect:
A kind of rotating disc type filtering ponds of 1 the utility model because filter cloth is thinner, are very easy to rinse well, clean very efficiently, during cleaning, the area that cleans filter disc only is equivalent to 1% of whole filter disc area, the overall cleaning water yield is also less, so lness ratio of plant is low, and total installed capacity power is low;
A kind of rotating disc type filtering ponds of 2 the utility model are because the design of filter disc vertical centering control blank pipe makes little floor space can guarantee big filter area, thereby reduced the pond appearance, reduced quantity of material and earth volume, significantly reduced construction costs, endurance requirement in base is low over the ground, the small investment of equipment ground;
A kind of rotating disc type filtering ponds of 3 the utility model adopt unique outer water intake mode and cleaning way, clean and adopt back purge system and aspirator, make the rotating disc type filtering ponds arrive superior performance;
A kind of rotating disc type filtering ponds of 4 the utility model, but continuous filtration when the filter cloth rotary disc filter cleans save backwash pond that many traditional filter tanks need, water tower etc., simple and compact device, and auxiliary device is few, and the investment of whole filtration system is low.
