Amy Li(Zheng and Refco Group Ltd, Shandong, Dongying, Guangrao, 274) 532Abstract: the FRU + O method is called double membrane method, mainly used for sewage deep treatment; experimental study in two grade water Hebei monosodium glutamate factory sewage treatment center as the raw water quality, the depth of treatment by UFRO method, and results show that the effluent quality can meet the water quality standard to the factory. Key words: FRU + O double membrane process; wastewater reuse; reclaimed water;Di1.99.s.0816.00501o:0360in10 - 2721.2s0CLC number: 88x7Document mark code: BArticle number: 0816 (000 - 5 - 2721 - 210 - 5090)A Hebei monosodium glutamate factory currently has three branch factories, annual production capacity of 300 thousand T sewage treatment capacity by about 40m3, 00 /, if the D will make the appropriate treatment of wastewater of monosodium glutamate factory after being reused, can realize the resource of sewage, and alleviate the plant water shortage is important the social and economic benefits in the growing shortage of water resources today.pilot test water inletYan PI Kuang and Fort circle.J beans solid + cured solidYi Wu Kuang Heng - bandit plaque bean,Fig. 1 pilot process flow chart1 determine the process11 process selectionWith the development of anti fouling membrane, separation technology was applied to wastewater membraneThe process of reuse is extensively used, and the pretreatment + ultrafiltration technology, which is introduced in the early treatment process, is adopted to make ultrafiltration (F from U)Ten reverse osmosis (O) R double membrane technology is the most widely used in the field of wastewater reclamation. The experiment adopts ultrafiltration (F + reverse osmosis (O), U) R doubleMembrane wastewater treatment process.In the trial period, stable filter system, with single gap adjustment overmining L fiber filter (hereafter referred to as PF before treatment, ultrafiltration and C)Experimental study was conducted. Therefore, after the system runs 684h, the membrane system is pre dualThe process is changed from disk filter to PF, and the specific content analysis is shown in figure 2C.Z.12 water source. This pilot test uses three water waste water as the water source. The main characteristics of raw water are high CD, O, high ammonia nitrogen, reused water quality and raw waterWater quality indicators are shown in table 1:Table 1 basic parameters of test water sourceCoffeecircle02004006008001000Run time / IlFig. 2 general trend of flux change of ultrafiltration membraneAs shown in Figure 2: secondary test ultrafiltration, no matter what process conditions are presentIt can operate stably.212 analysis of treatment effect of ultrafiltration system (see figure 3.)Eight hundred million seven hundred thousand and six hundred+ raw water C + UF water COD produced OD - U water ammonia nitrogen P production water C raw water ammonia nitrogen one PFCFODC production water ammonia nitrogen.withF,- - -.That y.L, a VY -, a -, - one! -,.U2008300.50f0,ChangenzymeLOOOReed. -1. process flow (see Figure 13)Run time / IlAnalysis of operation parameters of 2 double film system21 operation analysis of ultrafiltration systemFig. 3 effluent change curve of ultrafiltration systemReceived date: 090 - 720 - 72211 =.13 system operating parameters change analysis.1About the author: Shi Guiqing (91, 17, 1), Shandong, Dongying Province, 92 years graduated from Shandong 19 industry university, now engaged in water treatment technology.dayTianjinturnworkSeptember 2100Figure 3: ultrafiltration water CDrOc changes with the source of CDrOc, but always keep the removal rate of around 4%, although the C0PF CDrOc has a certain removal rate, but for ultrafiltration water CDrOcBasically no influence on whether or not PF ultrafiltration has no C removal rate for ammonia nitrogen.22I system operation analysis.QOThe conductivity of the produced water is higher than 80u / over. 00smc therefore222R system processing effectiveness analysis (Figure 5) see.OAs shown in Figure 5: O produced water, C
