Abstract
The present invention discloses one kind of combined membrane bioreactor (MBR)-reverse osmosis (RO) unit for treating non-degradable industrial effluent. The present invention includes one water tank for industrial effluent to flow in and with MBR membrane; one water tank for storing MRB membrane outlet water; one MBRM water pump with high sucking height and set between these two water tanks; and one RO unit with one water inlet connected via one RO water pump to the MBR membrane water tank, and two water outlets, including one connected to the MBR membrane water tank and the other for exhausting or reusing the treated water. The present invention combines MBR membrane and RO, and can treat non-degradable industrial effluent to reach the exhaust standard or even reuse standard.
Description
Technical field
The present invention 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 objective of the invention 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 one reverse osmosis (RO) combined apparatus of handling indegradable industrial effluent is provided.
Technical scheme of the present invention is: a kind of membrane bioreactor one 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.
Description of drawings

Fig. 2 handles ion exchange regenerant waste water schematic diagram for the present invention;
Fig. 3 handles lemon pickling waste waters schematic diagram for the present invention.
Embodiment
By shown in Figure 1, a kind of membrane bioreactor one reverse osmosis combined apparatus of handling indegradable industrial effluent is called for short the MBRM-RO treatment unit, is characterized in, it comprises that is introduced a pending waste water, and is placed with the water tank 1 of MBR film 2 in waste water; One for storing the water tank 4 of MBR film water outlet; One places the MBRM of the high suction lift between two water tanks to go out water pump 3; One is equipped with a water-in and two water outlet reverse-osmosis treated devices (RO) 6, be equipped with a RO intake pump 5 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 4 of storing the water outlet of MBR film by pipeline 7, another water outlet discharging or reuse water after treatment.
This device can be placed on automobile or other running gears, and automobile or running gear can directly move to treatment unit the scene of processing, handle, and is applicable to handle non-recurrent waste water.This device also can be installed on pending place, waste water water source, is applicable to handle regular waste water.
What Fig. 2 was represented is that the present invention handles 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 present invention handles 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. |
