醫院污水處理機器

、經濟效果

　　(1)、投資節省

　　采用本處理工藝，日排水10T左右的中型醫院，工程投資約20萬元，日排水5T左右的小醫院，工程投資約10萬元，相比于其它處理工藝，工程投資節省約20%。

　　(2)、運行費用較低

　　采用本處理工藝運行費用僅為0.2元/噸天，而A/O型或其改進型運行費用約為0.5~0.8元/噸天，費用可節約一半。

　　(3)、操作、維護簡便，無需對管理人員進行特殊培訓。

　　由于具備以上優點，本發明特別適合中小醫療機構，具有普遍推廣意義。

如下步驟處理污水：

　　(1)、醫療污水通過格柵過濾、集水井沉降，固液分離，液相污水進入水解酸化池，利用水解產酸菌的作用,將污水中不溶性有機物水解成可溶性有機物, 使大分子有機物質分解成小分子有機物質 ,并去除部分可溶性有機物, 提高污水的可生化性，為后序快速降解有機物創造有利條件;

　　(2)、水解酸化后的污水依序進入貧氧池、接觸氧化池、二次沉降池循環，使廢水處于缺氧、富氧循環變換的環境中，實現如下轉變：

　　-脫氮;將有機氮轉化為氨氮，通過好氧微生物硝化菌作用將氨氮轉化為亞硝態氮、硝態氮，再通過厭氧微生物反硝化菌將亞硝態氮、硝態氮轉化為氮氣，從污水中逸出，達到脫氮的目的;

　　-除磷;利用聚磷菌在缺氧環境中釋磷，而在富氧環境中過量吸磷的特性，形成高含磷量的污泥，達到除磷的目的;

　　-徹底降解有機物：在水解酸化的基礎上，利用好氧微生物富氧環境中快速繁殖的特性，厭氧微生物在缺氧環境中快速繁殖的特性，輪番降解有機物，將其轉化為污泥;

　　(3)、對污水消毒，使之達到排放標準;

　　(4)、定期清除污泥。

　　所述貧氧池的容積遠小于接觸氧化池的容積，當污水循環時，在貧氧池的停留時間很短，而在接觸氧化池的停留時間很長，使生化處理產生的污泥主要沉淀在接觸氧化池中。

　　所述貧氧池由調節曝氣池、貧氧池串聯組成，二者為連通器結構，通過改變調節曝氣池的曝氣度，使污水充分混合，水質均勻。

醫院污水處理運行結果

從監測結果可以看出，該工程處理后排放的廢水已達到GB8978-1996表2I級排放標準，也達到了本項工程的設汁要求。

醫院廢水處理流程工藝選擇原則為：

1)、傳染病醫院必須采用二級處理，并需進行預消毒處理。

2)、處理出水排入自然水體的縣及縣以上醫院必須采用二級處理。

3)、處理出水排入城市下水道(下游設有二級污水處理廠)的綜合醫院推薦采用二級處理，對采用一級處理工藝的必須加強處理效果。對于經濟不發達地區的小型綜合醫院，條件不具備時可采用簡易生化處理作為過渡處理措施，之后逐步實現二級處理或加強處理效果的一級處理。

Commissioning and operation of hospital sewage treatment

Biological aerated filter (BAF) is started by inoculation. After washing, the aerobic activated sludge is mixed with the raw sewage in a certain proportion and pumped into the biological aerated filter for 3 days. Then the water inflow and aeration volume are gradually increased from 10 m3/to 200 m3/d within a month. At the same time, the water inflow situation is observed every day and the water inflow volume is adjusted in time. After 200 m3/d water intake, continuous operation and full load operation, the removal rate of organic matter has reached the design re after a week of stable operation. After the biological aerated filter entered normal operation, the commissioning of chlorine dioxide e was started. After a week of debugging, the system went into normal operation.

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

The netizen said that when he passed Yujiahu Road yesterday morning, the well was pumping sewage. When he returned to this place at noon, the problem remained unsolved. Through the live video provided by the netizen, the reporter of Chutian Metropolitan Daily saw that black sewage constantly emerged from the well and spread 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 pouring out sewage. The reporter noticed that the overflowing sewage had extended to tens of meters. As soon as he approached, he could smell a distinct odor. In addition to the sidewalk where the well was located, a large amount of sewage flowed into an open parking lot nearby, and many citizens had to bypass it. Pass.

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