Abstract
The utility model discloses a membrane bioreactor-anti-penetration combination device for treating refractory degradation industrial wastewater. The characters are that the device consists of a water tank which is for introducing awaiting treatment wastewater in which is arranged with a MBR membrane, a water tank for storing MBR membrane effluent, a MBRM water out pump with high suction height which is arranged between the two water tanks, an anti-penetration treatment device(RO) which is arranged with a water inlet and two water outlets, a RO intake pump which is arranged between the water tank for storing MBR membrane effluent and the water inlet of the anti-penetration treatment device (RO) . One water outlet of the RO intake pump connects with the water tank for storing MBR membrane effluent by pipe, and the other water outlet exhausts and reuses the water after treatment. The device uses both anti-penetration (RO) and MBR membrane. By using excellent characteristics of the MBR membrane the wastewater after treatment which reaches the requirement of anti-penetration is transported to anti-penetration, which can make COD reduced, suspension matter of anti-penetration effluent and COD, etc, meet the standard of emission, even meet the standard of high quality reuse water.
Description
Technical field
The utility model relates to a kind of wastewater treatment equipment, particularly a kind of membrane bioreactor-reverse osmosis combined apparatus of handling indegradable industrial effluent.
Background technology
Industrial have much be difficult to biodegradable waste water, as water treatment intermediate ion exchange resin regenerative wastewater, the citric acid wastewater of boiler acid pickling discharging, EDTA Cleaning Wastewater etc.These trade effluents do not have the good treatment method at present as yet, are difficult to be degraded with bioremediation yet.MBR is the abbreviation of membrane bioreactor, and it is that MBR film with special use is placed in the wastewater disposal basin of biological treatment, with the organic oxidation in the water, improves biological treatment effect by the face high-concentration activated sludge, improves waste water treatment efficiency greatly.And to some trade effluent of difficult for biological degradation, owing to can not form active sludge, the MBR technology is difficult to use.
Summary of the invention
The purpose of this utility model is in order to make the MBR technology use the processing of some trade effluent of difficult for biological degradation, a kind of membrane bioreactor-reverse osmosis (RO) combined apparatus of handling indegradable industrial effluent to be provided.
The technical solution of the utility model is: a kind of membrane bioreactor-reverse osmosis combined apparatus of handling indegradable industrial effluent is characterized in that it comprises that is introduced a pending waste water, and is placed with the water tank of MBR film in waste water; One for storing the water tank of MBR film water outlet; One places the MBRM of the high suction lift between two water tanks to go out water pump; One is equipped with a water-in and two water outlet reverse-osmosis treated devices (RO), be equipped with a RO intake pump between the water tank of its water-in and the water outlet of storage MBR film, the one water outlet is connected with the water tank of storing the water outlet of MBR film by pipeline, another water outlet discharging or reuse water after treatment.
Because this device is with MBR film and reverse osmosis (RO) coupling, utilize the good characteristic of MBR film itself, send into reverse osmosis after wastewater treatment reached the reverse osmosis requirement, this reduces COD, indexs such as the suspended substance of reverse osmosis water outlet, COD reach emission standard, even can reach fine reuse water standard.

What Fig. 2 was represented is that the utility model is handled ion exchange regenerant waste water schematic diagram, be connected with MBRM-RO treatment unit 10 by pump 9 by contain ion exchange regenerant wastewater disposal basin 8, one outlet, 11 discharging and the reuse water after treatment of MBRM-RO treatment unit, in the wastewater disposal basin that turns back to the front of another outlet, before advancing the processing of MBRM-RO treatment unit, ion exchange regenerant waste water need add acid and add alkali, makes PH be transferred to neutrality.Water quality after treatment: SS ≈ 0, COD＜100mg/L.Through circular treatment, a small amount of waste water after concentrating is burned or other modes are handled.
What Fig. 3 was represented is that the utility model is handled lemon pickling waste waters schematic diagram, the waste water of lemon pickling wastewater disposal basin 12 after lime precipitation is handled to another wastewater disposal basin 13, add acid again and be adjusted to neutrality, enter MBRM-RO treatment unit 15 by pump 14, one outlet, 16 discharging and the reuse water after treatment of MBRM-RO treatment unit are in the wastewater disposal basin that turns back to the front of another outlet.Water quality after treatment: SS ≈ 0, COD＜100mg/L.
MBR film and reverse osmosis (RO) coupling and MBR film and reverse osmosis (RO) be the application characteristic comparison sheet separately:
| Characteristic | The problem that occurs when in the high organic industrial sewage of difficult degradation, using separately | Role when MBR and RO coupling (handling the high organic industrial sewage of difficult degradation) | |
| MBR | 1. use with biological treatment, can form one deck high-concentration activated sludge at face, strengthen biochemical action.2. membrane pore size is little, and filtration again guarantees out that water suspension is low.3. the film contamination resistance is strong. | Can not reach and reduce organic purpose in the water, can not form active sludge. | Utilize its contamination resistance strong, the aperture is little, strainability is good, go out the low characteristic of water suspension, guarantee that the RO influent quality is good, RO can use for a long time. |
| RO | 1. fenestra is very little, and is strong to separating substances ability in the water.2. film easily pollutes, and influent quality is required high. | Film is very fast blocked, can't use. | Utilize RO membrane sepn ability strong, when having MBR to guarantee its influent quality, give full play to the RO separation performance, remove organism in the water, guarantee that water outlet reaches emission standard. |
