      在濟南化糞池清理時我們都會遇到什么問題呢!這些問題的都是怎么解決的,那么今天就由濟南圣果管道清運有限公司教大家在化糞池清理時產生化學泡沫,怎么解決,產生的因素都有哪些?
      What problems will we encounter when cleaning the septic tanks in Jinan! How do we solve these problems? Today, we will teach you how to solve the problems of chemical foam when we are cleaning up the septic tanks by the Ji'nan holy fruit Pipeline Co., Ltd.
      1.化學泡沫
      1. chemical foam
      化學泡沫是由污水中的洗滌劑和一些工業表面物質在曝氣攪拌和吹脫的作用下形成的。隨著活性污泥的增加,大量洗滌劑或表面物質將被微生物吸收和分解,泡沫將逐漸消失。可以加入消泡劑,也可以加入粉狀活性炭,可以吸附一些活性劑和有害物質,還可以提供生物載體增加生物量。在正常的活性污泥系統中,由于某種原因會損失大量的污泥,導致氟/米急劇增加,并產生化學泡沫。
      The chemical foam is formed by washing and washing off the detergent and some industrial surface materials in the sewage. With the increase of activated sludge, a large number of detergents or surface substances will be absorbed and decomposed by microorganisms, and the foam will gradually disappear. It can be added with defoamer or powdered activated carbon, which can absorb some active agents and harmful substances, and can also provide biological carrier to increase biomass. In normal activated sludge system, a large number of sludge will be lost for some reason, resulting in a sharp increase in fluorine / rice and chemical foam formation.

      一、生物泡沫生產條件
      1. Production conditions of biological foam
      諾卡氏菌被認為是生物泡沫形成的主要原因。諾卡氏菌在高溫(> 20℃)下容易繁殖,富含油脂。因此,在流入廢水中油脂物質較多的處理廠或初沉池浮渣去除不完全的處理廠,容易產生生物泡沫。
      Nocardia is considered to be the main reason for the formation of biological foam. Nocardia is easy to reproduce in high temperature (> 20 ℃), and rich in oil. Therefore, it is easy to produce biological foam in the treatment plant or the initial sedimentation tank scum which is used to inflow waste water.
      在上述處理廠中,夏季比冬季更容易產生生物泡沫。雖然諾卡氏菌(Nocardia)的世代周期長而短,但大多數都超過9天。因此,生物泡沫更有可能在超低負荷活性污泥系統中產生。
      In the above treatment plants, biological foam is easier to produce in summer than in winter. Although the generation cycle of Nocardia is long and short, most of them are over 9 days. Therefore, biological foam is more likely to occur in ultra low load activated sludge system.
      二、生化池泡沫常用解決方案
      Two, biochemical pool foam commonly used solutions
      1.噴水
      1. water spray
      這是最常用的物理方法之一。通過噴灑水或珠子來打破漂浮在水面上的氣泡,從而減少泡沫。部分分散的污泥顆粒恢復了沉降性能,但混合溶液中仍存在絲狀細菌,因此泡沫現象無法完全消除。
      This is one of the most commonly used physical methods. By spraying water or beads to break bubbles that float on the surface of water, the foam is reduced. Partially dispersed sludge particles recovered their settling properties, but filamentous bacteria still existed in the mixed solutions, so the bubble phenomenon could not be completely eliminated.
      2.加入消泡劑
      2. Add defoamer
      可以使用具有強氧化性的殺菌劑,如氯、臭氧和過氧化物。還有由聚乙二醇和硅樹脂生產的商業試劑,以及氯化鐵和銅酸洗溶液的混合試劑。藥物的作用只能減少泡沫的生長,但不能消除泡沫的形成。然而,廣泛使用的殺菌劑通常具有負面影響,因為過量或不適當的給藥位置將大大減少絮凝細菌的數量和反應罐中的總生物量。
      Strong oxidizing fungicides such as chlorine, ozone and peroxide can be used. There are also commercial reagents produced from polyethylene glycol and silicone, as well as mixed reagents for ferric chloride and copper pickling solutions. The role of drugs can only reduce the growth of foam, but can not eliminate the formation of foam. However, widely used fungicides usually have a negative impact, because excessive or inappropriate dosing locations will significantly reduce the number of flocculating bacteria and the total biomass in the reaction tank.
      3.厭氧消化池回流上清液
      3. Return supernatant from anaerobic digestion tank
      先前的實驗表明,曝氣池表面氣泡的形成可以通過將厭氧消化池的上清液回流到曝氣池來控制。厭氧消化池上清液的主要功能是抑制紅球菌,但這種方法在幾個污水處理廠的實際運行不如實驗室成功。由于厭氧消化池上清液中含有高濃度的好氧基質和氨氮,會影響最終出水水質,應慎重采用。
      Previous experiments show that the formation of bubbles on the surface of the aeration tank can be controlled by returning the supernatant of the anaerobic digestion tank to the aeration tank. The main function of the supernatant of the anaerobic digestion tank is to inhibit the erythrococcus, but the actual operation of this method in several sewage treatment plants is not as successful as that in the laboratory. Due to the high concentration of aerobic matrix and ammonia nitrogen in the supernatant of the anaerobic digestion tank, the final effluent quality will be affected, so it should be carefully used.
