MBR工藝處理醫藥污水的特點：


采用膜生物反應器作為主處理單元，它具有抗沖擊能力強，出水水質優質穩定，其處理構筑物全部置于地下，占地面積小，布局合理。PLC柜置于地上控制室內，使管理較為簡單。 MBR工藝由于高效的固液分離作用，出水懸浮物濃度低，細菌和病毒失去了附著或包裹的屏障，易于被滅活，能有效去除SS和細菌。 膜組件的高效截留作用使反應器內保持了較高的生物量，提高了生物處理效率，由于MBR的截留作用使微生物富集，可使世代周期較長的硝化細菌得以保留和繁殖，從而到達了很好的脫氮效果。 反應器內微孔曝氣，不僅提高了充氧效率，而且優化了反應器的水力條件。微孔曝氣給生物接觸氧化提供了足夠的溶解氧，曝氣系統有助于膜兩側的翻水，強化了氣體對膜的剪切作用，有利于氣液兩相流間的傳質，使處理系統的正常穩定運行。 醫院廢水處理產生的剩余污泥中含有大量的細菌和病原微生物，處理不當會造成二次污染。所以維持在高污泥濃度條件下運行，可有效地解決排泥問題。MBR剩余污泥產量低，并且將剩余污泥回流到調節池中，從而達到系統污泥零排放，大大節省了污泥處理的經費問題，有利于污泥資源化管理。

問題突出表現在：建設滯后，農村污水處理設施覆蓋率偏低，農村58%的生活污水未得到有效處理。設施運行效率不高，農村生活污水處理設施建設普遍存在廠網建設不完善的問題。農村污水直排問題不容忽視，污水收集管線沒有接管入戶，都市人群赴郊區旅游導致農村集中排污現象加劇。缺乏運維經費和專業維護。北京市尚未出臺處理設施運行經費撥付辦法和標準，基層設施管理不到位、運行效率偏低。
工藝特點：加強處理效果的一級強化處理可以提高處理效果，可將攜帶病毒、病菌的顆粒物去除，提高后續深化消毒的效果并降低消毒劑的用量。其中對現有一級處理工藝進行改造可充分利用現有設施，減少投資費用,After hydrolysis and acidification, the wastewater enters oxygen-poor tank, contact oxidation tank and secondary sedimentation tank in order to circulate, so that the wastewater is in the environment of anoxic and oxygen-enriched cycle transformation, and the following transformation can be achieved.- Denitrification; converting organic nitrogen into ammonia nitrogen, transforming ammonia nitrogen into nitrite nitrogen and nitrate nitrogen through aerobic microbial nitrification bacteria, and then transforming nitrite nitrogen and nitrate nitrogen into nitrogen through anaerobic microbial denitrification bacteria, escaping from sewage- phosphorus removal; high phosphorus content sludge is formed by phosphorus accumulating bacteria releasing phosphorus in anoxic environment and absorbing excessive phosphorus in oxygen-rich environment.- Degrading organic matter thoroughly; On the basis of hydrolysis acidification, utilizing the characteristics of rapid propagation of aerobic microorganisms in oxygen-rich environment and rapid propagation of anaerobic microorganisms in anoxic environment, degrading organic matter in turn and transforming it into sludge(3) Disinfection of sewage to meet discharge standards(4) Regular removal of sludgeThe characteristics of sewage treatment methods in small and medium-sized hospitals are as follows: the volume of the oxygen-poor pool is much smaller than that of the contact oxidation pool. When the sewage circulates, the residence time in the oxygen-poor pool is very short, while the residence time in the contact oxidation pool is very long, so that the sludge produced by biochemical treatment is mainly deposited in the contact oxidation pool.The characteristics of sewage treatment methods in small and medium-sized hospitals are as follows: the oxygen-poor pool is composed of adjusting aeration pool and anoxic pool in series. The two pools are connected structure. By changing the aeration degree of the adjusting aeration pool, the sewage is fully mixed and the water is uniform.4. The sewage treatment method for small and medium-sized hospitals as described in claim 3 is characterized in that the sewage treatment station also includes a sludge concentration pond which is connected with a contact oxidation pond, and the sludge concentration pond is e with a reflux pipe.與調節曝氣池連通，回流管路上配有回水泵，開啟回水泵，將污泥濃縮池的上層污水泵回調節曝氣池，使下層的污泥濃縮，也使接觸氧化池中的污泥持續進入污泥濃縮池The characteristics of sewage treatment methods in small and medium-sized hospitals are as follows: chlorine dioxide is injected into the drainage pipe of secondary sedimentation tank; chlorine dioxide flow rate is accurately measured by metering pump to reduce residual chlorine residue; at the same time, water body is sufficiently mixed from the contact oxidation tank and aerated by blower to reduce dosage.6. The small and medium-sized hospital sewage treatment method described in Fig. 4 is characterized by that the sewage return flow R = 1:1, i.e. the sewage circulation flow: the treated discharge flow = 1:1.At present, the total number of medical units above county level (including industrial and mining enterprises hospitals, military hospitals, private hospitals and Sino-foreign joint venture hospitals, etc.) in our country (except Hong Kong Special Administrative Region, Macao Special Administrative Region and Taiwan region) is about 21,000, of which 1041 are tertiary first-class hospitals, accounting for about 5% of the total number of hospitals, 90% of which are small and medium-sized hospitals below secondary level, relatively speaking, large hospitals. All of them have more standardized wastewater treatment systems, and are e with professional maintenance and management. However, due to the reasons of fund, operation cost and personnel , a large number of small and medium-sized medical institutions are weak in the construction of medical wastewater treatment facilities, and their operation is not completely normal, which is a difficult and important point in current pollution control.The sewage discharged by hospitals consists of two parts, one is domestic wastewater, the pollutants are mainly organic matter, the other is medical wastewater, the pollutants are mainly nitrogen, phosphorus and so on. At present, most of the small and medium-sized medical institutions in our country generally adopt the first-level intensified treatment. The typical process is as follows.The characteristic of the first-level intensification process is that it can effectively control pathogens through disinfection process, but the removal effect of COD and BOD is not good and can not meet the re of environmental protection.In recent years, with the progress of social economy and the improvement of people"s awareness of environmental protection, more and more small and medium-sized medical institutions have built a number of secondary biochemical treatment facilities.  The processes adopted include A/O, SBR, oxidation ditch and contact oxidation.As can be seen from Table 1, three biological treatment methods, A/O, SBR and oxidation ditch, all have good treatment effect.However, for small and medium-sized medical institutions, due to the lack of funds and managers, there may be insufficient funds in the actual implementation process, or there may be inadequate management and excessive discharge.Relatively speaking, contact oxidation method is more suitable for sewage treatment in small and medium-sized medical institutions, but contact oxidation method lacks oxygen-deficient stage, so the ability of denitrification is weak. Nitrogen in effluent is basically converted to nitrate, ammonia nitrogen may reach the standard, and the essence of total nitrogen has not been removed.The purpose is to overcome the shortcomings of the above-mentioned treatment methods and provide a more suitable treatment method for sewage treatment in small and medium-sized hospitals. The treatment process of this method is simple, occupies less land, has low construction investment and operation cost. It can not only meet the sewage treatment standards, but also is easy to operate and manage, and has low re for the of operators.,大家紛紛表示，在今后的日常生活和環保行動中，將從我做起，從小事做起，節約用水，珍惜水資源，同時號召身邊的人一起節約能源，提升環保意識，努力建設和美邢臺！（通訊員 韓亞麗 王康）
