Description

The nitrated filtration unit of a kind of sewage disposal
Technical field
The utility model relates to the nitrated filtration unit of a kind of sewage disposal.
Background technology
At present in water treatment field; water filtration is mainly adopted to tank body filtering under pressure and filler gravity filtration with no pressure; its filtrate major part is horizontal distribution; its main drawback: in water, suspended substance is deposited in the surface of filtrate very soon; thereby open area is reduced; choked flow aquaporin; must shut down and carry out back flushing, need to build large-scale air blast machine room, and back flushing pump house; and for some time will be changed filtrate; operation energy consumption is high, and manipulation strength is large, and floor space is very large; civil engineering costs is high, and unit ton water cost is higher.When sewage disposal, because discharge water quality requirement improves, in existing sewage work, ammonia nitrogen often can exceed standard, and filtration unit cannot be realized nitrifying process, cannot remove ammonia nitrogen in water.The advantages such as the application at technical field of sewage transfer disc type filtration unit is more and more extensive, has treatment effect good, and water quality and quantity is stable, and running maintenance is simple and convenient.Need a kind of level of automation high, the high-efficiency sewage that floor space is less is processed nitrated, filtration unit.
Utility model content
The purpose of this utility model is to provide that a kind of to have level of automation high, and the running maintenance of equipment is more convenient, and floor space is less, realizes biological nitration reaction and removes ammonia nitrogen in water, sewage processing filtering device.
The purpose of this utility model is achieved through the following technical solutions:
The nitrated filtration unit of sewage disposal, is comprised of nitration reaction pond, carbon source adding set, gas blower and filtration unit; Described nitration reaction is provided with biological particles filler in pond, and the bottom in nitration reaction pond is provided with aeration tube, and aeration tube is connected with gas blower by pipeline.
Described filtration unit is provided with rotating disk filter screen, central drum and drive-motor.
The water outlet in described nitration reaction pond connects by the water-in of filter device for pipes.
The utility model principle of work: treatment sewage enters nitration reaction pond by water inlet pipe, nitration reaction is completed by aerobic autotrophic type microorganism, under aerobic state, utilize inorganic carbon mineralized nitrogen to be become to nitrate for carbon source, and then be oxidized to the process of nitrate, nitrifying process can be divided into two stages, first stage is by mineralized nitrogen, to be nitrite by nitrococcus, subordinate phase is nitrate by nitrifier by Nitrite transformation, the carbon source that adds microorganism needs by carbon source adding set, start gas blower and pass through aeration tube, to nitration reaction pond, blast air, microorganism adheres on biological particles filler, carry out nitration reaction.Then water enters filtration unit, and water inlet pipe connects dirt discharge groove, and dirt discharge groove communicates with central drum, and rotating disk filter screen is inner to communicate with central drum.Water inlet pipe enters after former water, due to the pressure difference inside and outside rotating disk filter screen, makes water pass through filter screen, and suspended substance is trapped within central drum, completes the filtration to sewage; When central drum inner suspension thing hold back mainly with after, start scavenging pump, by cleaning shower nozzle, rotating disk filter screen is cleaned, dirt discharge groove water level rises, suspended substance overflows by blow-off pipe, completes to clean to enter filtration condition.
The utility model compared with prior art, has following advantage and beneficial effect: the nitrated filtration unit of a kind of sewage disposal of the utility model, because rotating disk filter screen is thinner, be very easy to rinse well, and the overall cleaning water yield is also less; Can continuous filtration during the rotating disk filter gauze cleaning of filtration unit, save back flushing pond that many traditional filter tanks need, water tower etc., simple and compact device, auxiliary facility is few.The carbon source that adds microorganism needs by carbon source adding set, starts gas blower by aeration tube, to nitration reaction pond, blasts air, and microorganism adheres on biological particles filler, carries out nitration reaction, realizes biological nitration reaction and removes ammonia nitrogen in water.

Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment: as shown in Figure 1 and Figure 2, the utility model is comprised of nitration reaction pond (17), carbon source adding set (16), gas blower (15) and filtration unit (1); In described nitration reaction pond (17), be provided with biological particles filler (13), the bottom of nitration reaction pond (17) is provided with aeration tube (14), and aeration tube (14) is connected with gas blower (15) by pipeline.
Described filtration unit (1) is provided with rotating disk filter screen (2), central drum (12) and drive-motor (5).
The water outlet in described nitration reaction pond (17) connects by the water-in of filter device for pipes (1).
During the operation of the utility model device: treatment sewage enters nitration reaction pond (17) by water inlet pipe (11), nitration reaction is completed by aerobic autotrophic type microorganism, under aerobic state, utilize inorganic carbon mineralized nitrogen to be become to nitrate for carbon source, and then be oxidized to the process of nitrate, nitrifying process can be divided into two stages, first stage is by mineralized nitrogen, to be nitrite by nitrococcus, subordinate phase is nitrate by nitrifier by Nitrite transformation, the carbon source that adds microorganism needs by carbon source adding set (16), start gas blower (15) by aeration tube (14), to nitration reaction pond (17), blast air, microorganism adheres on biological particles filler (13), carry out nitration reaction.Then water enters filtration unit, because water inlet pipe (11) connects dirt discharge groove (10), dirt discharge groove (10) communicates with central drum (12), rotating disk filter screen (2) is inner to communicate with central drum (12), water inlet pipe (11) enters after former water, due to the inside and outside pressure difference of rotating disk filter screen (2), makes water pass through filter screen, suspended substance is trapped within central drum (12), completes the filtration to sewage; When central drum (12) inner suspension thing hold back mainly with after, start scavenging pump (4), by cleaning shower nozzle (7), rotating disk filter screen (2) is cleaned, dirt discharge groove (10) water level rises, suspended substance overflows by blow-off pipe (9), completes to clean to enter filtration condition.
As mentioned above, just can realize well the utility model.
