1、SBR Method and progress of studyingSummary: Have introduced the preface criticizing type intermittence production ,development and characteristic of France of active mud (SBR), survey SBR is mixing speed DO, pH , between OPR and influence to deal with result , is it is it get rid of phosphorus mecha
2、nism and SBR and other craft deal with newest progress of sewage synthetically to nitrify instead to nitrify.Keyword: Criticizing type intermittence active mud law of the preface (SBR), Progress , ProspectThe process system of active mud , use the most extensive treatment technology in the field of
3、sewage disposal at present. It is used in the sanitary sewage ,the treatment of municipal sewage and organism industrial sewage effectively, take measures to break through to traditional active mud technology only as second treatment technology tradition, can be as denitrification , tertiary treatme

SBR (sequencing batch reactor) law,namely preface criticize type intermittence active mud law, the active mud noticeable one active mud law to deal with new craft. It Japanese sewer association and American a few rich innovation meaning and strong wast

6、rized and applied . L.Irvine of U.S.A. carried on deep research to SBR craft in 1979, and Culver in Indiana state improved and put a SBR sewage treatment plant into operation in 1980. As too new-type to stop up the appearance which expose to the sun the angry device and software engineering that the

8、the sewage treatment plant, in addition water quality ,craft are simple that SBR melts , dealing with the result steadily, shock-resistant load strength is strong, it is fine that water quality happens, operate flexible ,floor space advantage such as being little and become including U.S.A. , German
9、y ,Japan , Australia , adding ,etc. a lot of hot craft that industrially developed country research and develop competitively. Taking Australia as an example, it is up to nearly more than 600 to build up a sewage treatment plant which has adopted SBR craft in more than 10 years in the past.Middle pe
10、riod began the application study to SBR law in the 1980s in our country.1985, Shanghai Wusong meat is it is it is it stand to put our country into operation first SBR law sewage disposal to develop to unite, designing 2400t/ d of amount of water dealt with, the operation result is good. Already ther
11、e are two large-and-middle-scale sewage treatment plants which adopt SBR craft in Kunming of Yunnan Province at present, it is in sound condition to run. The sewage treatment plant that Tianjin economic and technological development zone 100,000t/ d adopts SBR craft puts into operation recently too.
12、 According to studying the situation both at home and abroad, SBR law is a kind of high-efficient, economy, reliable waste water treatment method which is suitable for the national conditions of our country.1.2 Technological processMain reactor of the intermittence type active mud law, expose to the
13、 sun angry operation of pool it operates to be to flow into , react , precipitate , discharge and leave unused five processes not to make up. The sewage is according to the array in the reactor, enter each response process intermittently, each operation ,SBR of reactor operate at time arranging acco
14、rding to order that intermittence run too.Before not flowing into process implement , leave unused process treated sewage already discharge, expose to the sun the remaining active mud and mixture of the high density in the angry pool. When the sewage is run into and flowed into ,exposing to the sun
15、the angry pool can play a role in regulating the pool , is it expose to the sun angry to can is it expose to the sun angry result in advance to make , can make mud regeneration to go on, resume its activation.The response process is main a process of SBR craft . Is it is it book volume to reach as s

According to reflecting the degree that the need reaches, it is angry that the trace of carrying on short time is exposed to the sun, in order to blowand take off the bubble or nitrogen seized on the mud , so as to ensure the mashed of arranging goes on smoothly.Arranging the mud process, it is angry and mix that stop exposing to the s
