Description
Technical Field
The utility model relates to a waste water treatment recovery unit based on prevent membrane pollution.
Background
The membrane separation technology is a high and new technology, has wide application fields, and is widely applied to the fields of water treatment, electronics, food, environmental protection, chemical industry, metallurgy, medicine, biology, energy, petroleum and the like at present. The application of the membrane separation technology in water treatment mainly comprises the following steps: advanced treatment of water (preparation of pure water, direct drinking water and the like), treatment and recycling of paper-making wastewater, dye industrial wastewater, oily wastewater, emulsified oil wastewater, electroplating wastewater, food industrial wastewater and the like. The membrane separation water treatment technology is a general term of a large class of technologies, and according to the pore size, the classification of membranes comprises: microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, reverse osmosis membranes, and the like; the membrane materials are divided into inorganic membranes and organic membranes. The membrane separation products all utilize the interception capability of a specially manufactured porous material to remove impurities with certain particle size in water in a physical retention mode. Under the driving of pressure, the substances with smaller size can reach the other side of the membrane through micropores on the fiber wall, and the substances with larger size cannot permeate the fiber wall to be intercepted, so that the aim of screening components with different sizes in the solution is fulfilled.
TABLE 1-1 separation techniques and separation Properties
Table 1-1 shows the size of various impurities in water and the separation method used to remove them. Reverse osmosis is mainly used to remove dissolved inorganic salts from water; the ultrafiltration can remove viruses, macromolecular substances, colloids and the like; the microfiltration can generally remove bacteria and dust in water and has good turbidity removal effect. These are traditional filtration (such as sand filtration, multi-media filtration, etc.) which cannot be tested, so that the filtration treatment of wastewater by using membrane separation technology is becoming a technical hotspot of wastewater treatment in recent years. The major problems in membrane separation technology are membrane fouling and concentration polarization. The membrane pollution is mainly caused by the phenomenon that the membrane pore diameter is reduced or blocked due to adsorption and precipitation in the membrane surface or membrane pores caused by the physical-chemical interaction or mechanical action between particles, colloids, microorganisms or macromolecules in the treated materials and the membrane, so that the membrane flux and the separation characteristic of the membrane are irreversibly changed. Concentration polarization means that the trapped solute is accumulated on the membrane surface, the concentration of the trapped solute can be gradually increased, the solute close to the membrane surface diffuses to the feed liquid body in the opposite direction under the action of concentration gradient, and a solute distribution boundary layer is formed on the membrane surface in an equilibrium state, so that the movement of small molecular substances such as solvent is ultra-hindered.
At the in-process that uses membrane separation technique to handle water, because the membrane surface that concentration polarization leads to can pile up a large amount of impurity, if not in time clearance, then can lead to impurity deposit in membrane surface membrane pore easily, make the membrane pore block up or diminish, cause the phenomenon of membrane pollution, thereby the permeation rate who makes the membrane descends, the life of membrane can greatly reduced, traditional structural style's membrane lacks the good clearance mechanism to membrane pollution attachment, consequently, the frequency of more changing the membrane is higher, make manufacturing cost increase, also influence the efficiency of production simultaneously.
