ater separation devices on top of the tank. The methane is discharged or used by water seal, and the separated water automatically flow back to the tank bottom along pipeline. Therefore, the internal circulation is brought out. Through the bottom threephase separator, the wastewater continues to rise into the upper essence treatment part to reduce the anic matter in waste water for further. 廢水在厭氧發(fā)酵時最適宜的溫度有中溫( 36177。2℃ )或高溫( 53177。3℃ ),應根據(jù)該廢水性質(zhì),選擇高溫厭氧發(fā)酵。 青 島 國 橋 進 出 口 有 限 公 司 Qingdao ChinaBridge Import amp。 Export Co.,Ltd. 14 The suitable temperature for wastewater in anaerobic fermentation is middle temperature (36 177。 2 ℃ ) or high temperature (53 177。 3 ℃ ). It should base on the wastewater and select the appropriate anaerobic fermentation temperature. 厭氧菌中的產(chǎn)甲烷菌最適宜生長的 PH 值在 之間,而該類廢水的 PH 值在 67 之間,因為廢水進入?yún)捬豕藓笥捎诠迌?nèi)廢水的稀釋作用和微生物作用,幾乎瞬間就跟厭氧罐內(nèi)的 PH 環(huán)境一至,而不用調(diào)節(jié)進水的 PH 值。 The suitable growth PH value of methanogen in anaerobe is between . For the wastewater after adjustment, the PH value is between . When the wastewater entering the anaerobic tank, there is no need to adjust the inlet water PH value because by the dilution and microbial action, the wastewater will immediately regulate the PH value to the same as environment in the anaerobic tank.
