As shown in Figure 1, a kind of water treatment integrating device, comprises multi-medium filtering device 110 and membrane biological reaction apparatus 120, and multi-medium filtering device 110 is connected with membrane biological reaction apparatus 120 by the first outlet conduit 116.
Multi-medium filtering device 110, comprise multi-medium filtering pond body 112, pretreated water inlet channel 114 and the first outlet conduit 116, multi-medium filtering pond body 112 comprises the multimedium supporting layer 1124 and multimedium packing layer 1122 that arrange successively from bottom to top, pre-treatment inlet channel is connected with multimedium packing layer 1122, and the first outlet conduit 116 is connected with multimedium supporting layer 1124.
Multi-medium filtering device 110 refers to utilize one or more filtration mediums, under pressure water higher for turbidity by certain thickness granular or non-grain material, thus effectively removes the device that suspended impurity makes water clarify. Specifically to, in the present embodiment, pretreated water inlet channel 114 water side is provided with water distributor 1146, the water outlet of this water distributor 1146, just to multimedium packing layer 1122, filters so that pretreated water evenly to flow into multimedium packing layer 1122. Certainly, pretreated water inlet channel 114 water side also can not arrange water distributor 1146, as long as namely can ensure that pretreated water passes through pretreated water inlet channel 114 and flows into multimedium packing layer 1122.
Membrane biological reaction apparatus 120, it is connected with multi-medium filtering device 110 by the first outlet conduit 116, membrane biological reaction apparatus 120 comprises aerobic reaction pond 122 and membrane module 124, aerobic reaction pond 122 is connected with the first outlet conduit 116, membrane module 124 is arranged at aerobic reaction pond 122, membrane module 124 comprises the filtering unit 1242 that the water in aerobic reaction pond 122 can carry out filtration treatment, and for discharge unit 1242 after filtration filter after the product water water outlet 1244 of water.
Membrane biological reaction apparatus 120 is by arranging membrane module 124, utilize the active sludge in filtering unit 1242 trap water of membrane module 124 and larger molecular organics, instead of traditional biological process technology end second pond, bio-reactor keeps high reactivity sludge concentration, improve biological treatment organic loading, thus reduce sewage treatment facility floor space, and by keeping low sludge loading to reduce surplus sludge volume.
Above-mentioned water treatment integrating device, in use, pretreated water flows through multimedium packing layer 1122 and multimedium supporting layer 1124 successively through pretreated water inlet channel 114, with the suspended impurity removed in pretreated water; Then the aerobic reaction pond 122 that pretreated water flows to membrane biological reaction apparatus 120 through the first outlet conduit 116 carries out aerobic reaction, with the organism removed in pretreated water; Final water flows out by producing water water outlet 1244 after the filtering unit 1242 of membrane module 124 filters, and reclaims so that follow-up use. So, multi-medium filtering device 110 is connected by the first outlet conduit 116 with membrane biological reaction apparatus 120, can process the pollutent in pretreated water continuously, and has the carrying out of order to process according to the contaminant component in pretreated water, process better effects if, it is to increase effluent quality.
Wherein, what multi-medium filtering pond body 112 adopted is fall streaming to run, and is followed successively by multimedium supporting layer 1124 and multimedium packing layer 1122 from bottom to top. According to the law of universal gravitation, the pretreated water that pretreated water inlet channel 114 exports directly can flow through multimedium packing layer 1122 and multimedium supporting layer 1124 successively under the action of gravity of self, it is not necessary to additionally provides propulsion source. Simultaneously, multi-medium filtering pond body 112 is connected with membrane biological reaction apparatus 120, according to Psasca's law, and liquid transfer pressure, thus ensure that multi-medium filtering device 110 and membrane biological reaction apparatus 120 have all been in pressure working order, ensure the continuity of water treatment procedure. Suspended impurity in pretreated water is first carried out filtration treatment by multi-medium filtering device 110 by pretreated water, enter membrane biological reaction apparatus 120 again to process, the membrane module impurities in water of pre-treatment more than 124 that can slow down membrane biological reaction apparatus 120 on the one hand carries out the pressure of filtration treatment, ensure the stability of membrane module 124 filter effect, make water outlet water quality reaching standard; Also improve the efficiency of water treatment on the other hand.
Referring to Fig. 1, wherein in an embodiment, water treatment integrating device can also comprise active carbon filtering device 130, is arranged between multi-medium filtering device 110 and membrane biological reaction apparatus 120. Active carbon filtering device 130 comprises activated carbon filtration pond body 132 and the 2nd outlet conduit 134, activated carbon filtration pond body 132 comprises the gac supporting layer 1322, active carbon filler layer 1324 and the gac clear layer 1326 that arrange successively from bottom to top, gac supporting layer 1322 is connected with the first outlet conduit 116 one end away from multi-medium filtering pond body 112,2nd outlet conduit 134 one end is connected with gac clear layer 1326, and the other end is connected with the aerobic reaction pond 122 of membrane biological reaction apparatus 120.
By setting up active carbon filtering device 130, pretreated water is after multi-medium filtering device 110 filters, can first again filter through active carbon filtering device 130, then biochemical reaction occurs in the aerobic reaction pond 122 entering membrane biological reaction apparatus 120 by the 2nd outlet conduit 134.
