.醫院放射性污水處理

1 醫用放射性同位素污水的來源

醫用放射性同位素污水的主要來源包含病人服用放射性同位素藥物之后產生的排泄物；與放射性同位素物質接觸的醫用藥具；
醫用標記化合物配制和傾倒多余劑量的放射性同位素。

2 醫用放射性同位素污水的水質水量

同位素室排放的污水可分為兩部分，一部分未被放射性同位素污染的污水可按一般生活污水處理排放；
另一部分為被放射性同位素污染的污水，必須經過處理，使其放射性濃度降低到一定標準才可排放。


3 放射性污水處理方法

對于濃度高、半衰期長的放射性污水，一般將其貯存在容器中，使其自然衰變。
對于濃度低、半衰期較短的放射性污水，排入地下貯存衰變池，貯存一定時間使其放射性同位素通過自然衰變，當放射性同位素濃度降低到管理限值時再排放。
貯存、衰變池一般分為兩種型式：間歇式和連續式。
(三)潛水泵：第運行8000~10000小時保養一次(按說明收要求進行),醫院污水處理所用工藝必須確保處理出水達標，主要采用的三種工藝有：加強處理效果的一級處理、二級處理和簡易生化處理
醫院污水處理設備

一.醫院污水的來源
醫院排放廢水的主要部門和設施有：診療室、化驗室、病房、洗衣房、X光洗印、同位素治療診斷室、手術室等；

還包含醫院行政管理和醫務人員排放的生活污水、食堂、宿舍排水。
二醫院污水的水量
醫院及醫療機構的性質和規模不同。則其排放污水的量也有所不同。
醫院內部各個不同的部門和設施排放污水的水量也有各自的特點。
隨著生活水平提高和醫療設施條件改善，一般大、中型醫院的用水量和排水量都有較大的增加。


三醫院污水的水質特征
醫院污水的主要污染物包含病原性微生物、有毒、有害的物理化學污染物和放射性污染物三大類。


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.,污水經提升后進入混凝沉淀池進行混凝沉淀，沉淀池出水進入接觸池進行消毒，接觸池出水達標排放。調節池、混凝沉淀池、接觸池的污泥及柵渣等污水處理站內產生的垃圾集中消毒外運,所采用材質比水輕，能在水中均勻舒展，對氣泡作密集性多層次的切割，大大提高了溶解氧的傳遞補速率，減少風量，節約能耗。由于絲長材質經特殊配方，結構獨特，其在水中對微氣泡有吸附作用，填料載著生物膜在整個生物池中,始終保持立體空間的密度和均勻布置，使水、氣、生物膜充分接觸，提高了有機物去除率,從而避免消毒劑用量過大對環境產生的不良影響。醫院污水經化糞池進入調節池，調節池前部設置自動格柵，調節池內設提升水泵  襄樊 醫院污水處理設備 售后/多少錢

醫院污水處理原則  

    醫院排出的污水必須經過處理和嚴格消毒，一般應符合下列要求：

    一、已消毒處理的污水，每次取樣500毫升進行檢查，連續3次都未檢到腸道致病菌和結核桿菌。

    二、大腸桿菌群數不得超過500個／升。

    三、如果進行漂白粉消毒(即氯化法)，要求接觸時間和接觸池出水中的余氯含量應達到要求，其中綜合醫院污水接觸漂白粉時間不得少于1小時，余氯含量不得低于4～5毫克／升，腸道傳染病醫院污水不得少于1小時，余氯不低于4～5毫克／升，結核病醫院污水不得少于1.5小時，余氯含量不低于6～8毫克／升。

    四、為了提高醫院污水處理效果，在消毒以前必須進行一級處理和二級處理，必要時還要進行三級處理。

    五、污水處理流程不僅要根據水質要求來確定，還要考慮醫院污水的排向要求(指根據排入地下水道、農作物灌溉區、魚貝類養殖場或排入海域的不同作出不同的處理方案)。
