医院污水处理机器

、经济效果

　　(1)、投资节省

　　采用本处理工艺，日排水10T左右的中型医院，工程投资约20万元，日排水5T左右的小医院，工程投资约10万元，相比于其它处理工艺，工程投资节省约20%。

　　(2)、运行费用较低

　　采用本处理工艺运行费用仅为0.2元/吨天，而A/O型或其改进型运行费用约为0.5~0.8元/吨天，费用可节约一半。

　　(3)、操作、维护简便，无需对管理人员进行特殊培训。

　　由于具备以上优点，本发明特别适合中小医疗机构，具有普遍推广意义。

如下步骤处理污水：

　　(1)、医疗污水通过格栅过滤、集水井沉降，固液分离，液相污水进入水解酸化池，利用水解产酸菌的作用,将污水中不溶性有机物水解成可溶性有机物,使大分子有机物质分解成小分子有机物质 ,并去除部分可溶性有机物,提高污水的可生化性，为后序快速降解有机物创造有利条件;

　　(2)、水解酸化后的污水依序进入贫氧池、接触氧化池、二次沉降池循环，使废水处于缺氧、富氧循环变换的环境中，实现如下转变：

　　-脱氮;将有机氮转化为氨氮，通过好氧微生物硝化菌作用将氨氮转化为亚硝态氮、硝态氮，再通过厌氧微生物反硝化菌将亚硝态氮、硝态氮转化为氮气，从污水中逸出，达到脱氮的目的;

　　-除磷;利用聚磷菌在缺氧环境中释磷，而在富氧环境中过量吸磷的特性，形成高含磷量的污泥，达到除磷的目的;

　　-彻底降解有机物：在水解酸化的基础上，利用好氧微生物富氧环境中快速繁殖的特性，厌氧微生物在缺氧环境中快速繁殖的特性，轮番降解有机物，将其转化为污泥;

　　(3)、对污水消毒，使之达到排放标准;

　　(4)、定期清除污泥。

　　所述贫氧池的容积远小于接触氧化池的容积，当污水循环时，在贫氧池的停留时间很短，而在接触氧化池的停留时间很长，使生化处理产生的污泥主要沉淀在接触氧化池中。

　　所述贫氧池由调节曝气池、贫氧池串联组成，二者为连通器结构，通过改变调节曝气池的曝气度，使污水充分混合，水质均匀。

医院污水处理运行结果

从监测结果可以看出，该工程处理后排放的废水已达到GB8978-1996表2I级排放标准，也达到了本项工程的设汁要求。

医院废水处理流程工艺选择原则为：

1)、传染病医院必须采用二级处理，并需进行预消毒处理。

2)、处理出水排入自然水体的县及县以上医院必须采用二级处理。

3)、处理出水排入城市下水道(下游设有二级污水处理厂)的综合医院推荐采用二级处理，对采用一级处理工艺的必须加强处理效果。对于经济不发达地区的小型综合医院，条件不具备时可采用简易生化处理作为过渡处理措施，之后逐步实现二级处理或加强处理效果的一级处理。

Commissioning and operation of hospital sewage treatment

Biological aerated filter (BAF) is started by inoculation. Afterwashing, the aerobic activated sludge is mixed with the raw sewagein a certain proportion and pumped into the biological aeratedfilter for 3 days. Then the water inflow and aeration volume aregradually increased from 10 m3/to 200 m3/d within a month. At thesame time, the water inflow situation is observed every day and thewater inflow volume is adjusted in time. After 200 m3/d waterintake, continuous operation and full load operation, the removalrate of organic matter has reached the design requirements after aweek of stable operation. After the biological aerated filterentered normal operation, the commissioning of chlorine dioxideequipment was started. After a week of debugging, the system wentinto normal operation.

Chutian Metropolitan Daily News (reporter Yu Yuan) yesterday,some netizens reported to Chutian Metropolitan Daily that there wasa well blocked near Yujiahu Road in Guanggu, which caused a lot oftrouble to citizens'travel because of continuous sewage and badsmell.

The netizen said that when he passed Yujiahu Road yesterdaymorning, the well was pumping sewage. When he returned to thisplace at noon, the problem remained unsolved. Through the livevideo provided by the netizen, the reporter of Chutian MetropolitanDaily saw that black sewage constantly emerged from the well andspread to the distant road surface.

At about 2 p.m. yesterday, the reporter arrived at Yujiahu Road.At this time, the well mentioned by the netizen was still pouringout sewage. The reporter noticed that the overflowing sewage hadextended to tens of meters. As soon as he approached, he couldsmell a distinct odor. In addition to the sidewalk where the wellwas located, a large amount of sewage flowed into an open parkinglot nearby, and many citizens had to bypass it. Pass.

Yesterday, the reporter reflected the situation on the spot tothe unit under the well, and the relevant staff said that theywould send someone to repair it immediately.
