湘潭醫(yī)院污水處理設(shè)備
小型醫(yī)院地埋式一體化污水處理設(shè)備
1、污泥處理
污泥池中的污泥通過好氧消化后,定期處理。
2、防滲措施
本污水處理站中采用鋼筋混凝土制作的池,為了避免地下水滲入或污水滲出,鋼筋混凝土采用防滲設(shè)計(jì)。
3、除臭措施
由于缺氧池、好氧池、污泥池都需充氧曝氣,因此曝氣后溢出水面的氣體有一定的臭味,如果這些臭氣不加以處理勢(shì)必影響周圍環(huán)境,造成二次污染。我們將調(diào)節(jié)池、缺氧池、好氧池、污泥池頂蓋上引出通風(fēng)口,整套設(shè)備運(yùn)行**,管理方便,其設(shè)備投資相應(yīng)較小。
4、降噪措施
本污水處理站*主要的噪聲來源是鼓風(fēng)機(jī),為此我們采用一系列措施降低噪聲。本污水處理站采用羅茨風(fēng)機(jī)布置在風(fēng)機(jī)房?jī)?nèi),在風(fēng)機(jī)基礎(chǔ)下設(shè)置隔振墊,并在風(fēng)機(jī)進(jìn)風(fēng)口上安裝消聲器,在出風(fēng)口上安裝可曲撓橡膠接頭,以減少振動(dòng)產(chǎn)生的噪聲。
充氧采用水下曝氣機(jī),噪音小,充氧效率高。曝氣機(jī)安裝在水下,可以隨時(shí)提升上來維修,技術(shù)特點(diǎn)如下:
⑴氧溶解率高,微小氣泡所占比列大,充氧效率高且充氧面積寬;
⑵池中無死區(qū),夾帶氣泡的水平水流*沖刷池底的每個(gè)角落;
⑶結(jié)構(gòu)簡(jiǎn)單、緊湊、機(jī)組壽命長(zhǎng),能承受大負(fù)荷的軸承、采用油浴的轉(zhuǎn)軸機(jī)械密封和吸入葉輪腔內(nèi)的空氣防止工作時(shí)與密封件接觸,這些都保證曝氣機(jī)在24小時(shí)連續(xù)工作,長(zhǎng)期*運(yùn)行;
⑷與常規(guī)的鼓風(fēng)曝氣方式相比,無需建設(shè)鼓風(fēng)房,無需氣泵和輸氣管道,安裝方便,維修工作量小,占地面積少;
⑸使用靈活,當(dāng)池內(nèi)設(shè)有多臺(tái)沉水式曝氣機(jī)時(shí),可根據(jù)需要增減曝氣機(jī)的運(yùn)行數(shù)量,容易實(shí)現(xiàn)曝氣量的調(diào)節(jié)和節(jié)能效果;
⑹曝氣機(jī)工作時(shí),兼具有攪拌功能,避免污泥在池低沉淀;當(dāng)進(jìn)氣口關(guān)閉時(shí),也可作為攪拌機(jī)使用。
The sources and components of hospital sewage are complex, including Y pathogenic microorganisms, toxic and harmful physical and chemical pollutants and radioactive contamination. It has the characteristics of space pollution, acute infection and latent infection. Without ** treatment, it will become an important way for the spread of epidemic diseases and seriously pollute the environment. Hospital sewage is contaminated by pathogenic microorganisms such as feces, infectious bacteria and viruses. It is infectious and can cause diseases or injuries. Hospital sewage contains acid, alkali, suspended solids, BOD, COD, animal and vegetable oils and other toxic and harmful substances. Dental **, printing and laboratory processes produce sewage containing heavy metals, disinfectants, organic solvents, some of which are carcinogenic, teratogenic or mutagenic, endangering human health and have a long-term impact on the environment. Isotope** and diagnosis produce radioactive sewage. Radioisotopes produce a-, beta-and gamma-radioactivity during decay, which accumulates in the human body and endangers human health.
