Biomembrane process is more applied at sewage and field of waste water treatment gradually, technology of biological membrane used more biological sewage treatment technology in the process field of sewage in recent years, compared with the sewage treatment process of routine, microbial film feedwater can have higher contaminant removal efficiency, stablizes effluent quality.Technology of biological membrane floor space is few, is beneficial to and is realizing separated practices.And biomembranous processing parameter is less, convenient operation manages, and is easy to the operation realizing integration.But in biomembranous treating processes, membrane pollution problem is a fundamental issue of restriction technology of biological membrane always.Therefore in order to reduce membrane fouling rate, have developed a kind of new village waste disposal plant, the membrane bioreactor of preposition sandstone filter tank and aeration type is be combined with each other, improve the removal efficiency of membrane bioreactor, have larger directive significance to rural sewage treatment.
To the equipment of aeration tank oxygen supply in the existing a kind of waste water activated sludge process water treatment procedure of aerating apparatus of the present invention.
Aeration refers to and artificially in biochemical aeration tank, passes into air by suitable equipment, to reach the object of expection.Aeration not only makes liquid-to-air contact oxygenation in pond, and due to agitated liquid, accelerates oxygen in air and shift in liquid, thus complete the object of oxygenation; In addition, aeration prevents pond inner suspension body from sinking in addition, strengthens the object that in pond, organism contacts with dissolved oxygen with microorganism, thus ensures that in pond, microorganism is under the condition having sufficient dissolved oxygen, to oxygenolysis organic in sewage.The quality of aerating apparatus, not only affects biochemical wastewater treatment effect, and directly has influence on Treatment stations occupation of land, investment and working cost.
Fine fack in the present invention, Grill space 6cm, gap 3mm, fine fack is mainly used in filtering domestic refuse in sanitary sewage, prevents bulk foreign material from entering aeration type membrane biological reaction tank, causes the damage of film.
Preliminary sedimentation tank 2 in the present invention is of a size of 5m × 3m × 2.8m, because the water quality of resident living sewage and the water yield have ununiformity, and the effect that preliminary sedimentation tank mainly plays homogenizing water quality, regulates the sewage water yield, prevents load impact.
Submerged hollow fiber membrane 14 is provided with in aeration type membrane biological reaction tank 4, membrane pore size is 0.1 μm, the solid-liquid separation effect of mud is played by the suction of pump, aerating apparatus in pond plays very strong shearing action to submerged hollow fiber membrane 14 surface, thus stops submerged hollow fiber membrane 14 to pollute.
In order to strengthen de-P effect, be placed with 30% excellent PAC in feed tank 6, dosing pump flow is 0.3 side/h, PAC main component Al

3, itself and P in sewage form chemical precipitation and enter in mud, are reached the removal effect of P by the efficient crown_interception of submerged hollow fiber membrane 14.High-concentration activated sludge in aeration type membrane biological reaction tank 4 is to BOD, COD, NH in sewage
4 +-N has very strong removal effect.
Due to residential quarter sanitary sewage water quality and water yield fluctuation larger, for the ease of Automated condtrol and management, whole Sewage treatment systems adopts PLC two-position controller 16 to regulate and control each structures device parameter, PLC two-position controller 16 pairs of preliminary sedimentation tanks and feed tank, all types of of sludge reflux place pump up regulating and controlling effect.
Beneficial effect of the present invention is: 1. because aeration type membrane biological reaction tank 4 film high-performance bio crown_interception, sludge concentration is high, and sludge age is long, improves mud nitrification effect, effectively can remove BOD, COD, NH
4 +-N.Meanwhile, the auxiliary and chemical removal efficiency except P, P is very high, and water outlet P content is at below 0.3mg/L, and aeration type membrane biological reaction tank 4 technique excess sludge is few simultaneously, and sludge organism is active strong, and when load variations, this system effluent quality is also very stable.
2. because whole Sewage treatment systems structures are few, submerged hollow fiber membrane 5 compact construction in aeration type membrane biological reaction tank 4, whole system facility floor space is few; Meanwhile, be equipped with PLC two-position controller 16, manning is few, and whole system level of automation is high, flexibly stable.
When the present invention works, resident living sewage filters out after bulk foreign material by water inlet pipe 1 through fine fack, enters preliminary sedimentation tank 2 by preliminary sedimentation tank lift pump 3, and due to community life sewage flooding quantity, variability is very large in time, and therefore sanitary sewage also plays regulating effect.After sanitary sewage pond exceedes threshold value, sewage is got to aeration type membrane biological reaction tank 4 by PLC two-position controller 16 controlling diaphragm biological reaction tank lift pump 5,30% excellent PAC is removed P agent according to the flow of 0.3 side/h and gets to aeration type membrane biological reaction tank 4 by PLC two-position controller 16 control pump 7 simultaneously, PLC two-position controller 16 controls gas blower 15 pairs of aeration type membrane biological reaction tank 4 aerations, the shearing force simultaneously produced is cleaned film surface, thus effectively prevents fouling membrane.
Submerged hollow fiber membrane 14 has very strong filtration capacity and makes active sludge have very strong biological activity, makes BOD, COD, NH4+-N and P in sewage have very strong removal efficiency.Meanwhile, auxiliary and chemical agent PAC precipitates P in sewage, and the removal efficiency of P in sewage is improved greatly.The solid-liquid separation effect of aeration type membrane biological reaction tank 4 makes after treated water passes through, and discharges through outlet conduit.In aeration type membrane biological reaction tank 4, excess sludge is discharged by pump 9 and is entered sludge sump 8.And the not good sewage for the treatment of effect by reflux pump 13 by sewage backflow to preliminary sedimentation tank, after mixing with water inlet, again enter aeration type membrane biological reaction tank 4 process.
