地埋式小型污水處理設備采用(yong)了常規的鼓(gu)風機措施外(如隔(ge)振墊、音器等),還在(zai)鼓(gu)風機房內壁設置(zhi)了新型吸音材料,使設備(bei)運行時的噪音低(di)于50分貝(bei),減輕了對周圍環境的影響。
填(tian)(tian)料(liao):本工藝采用(yong)新型(xing)(xing)立體彈性(xing)填(tian)(tian)料(liao),層密集型(xing)(xing)高效生化填(tian)(tian)料(liao),該(gai)填(tian)(tian)料(liao)具(ju)有(you)比表面積大(da)、使用(yong)壽命長、易掛膜、耐腐蝕(shi)等優特點。同時該(gai)填(tian)(tian)料(liao)具(ju)有(you)定的(de)剛度,能對污水中的(de)氣泡(pao)作多層次(ci)的(de)切割,使溶解效率(lv)增高,再則填(tian)(tian)料(liao)與填(tian)(tian)料(liao)之間不(bu)易結(jie)團(tuan),避免了化池的(de)堵塞。
曝氣(qi)器(qi):本(ben)工藝(yi)采用微(wei)孔曝氣(qi)器(qi),其溶解轉(zhuan)移率比其它曝氣(qi)器(qi)高,大特點(dian)是不(bu)老化(hua)、重量(liang)輕、使(shi)用壽命長,同時具有耐腐(fu)蝕、不(bu)易堵塞等優特點(dian)。
沉(chen)(chen)(chen)淀(dian)池(chi)(chi):污(wu)(wu)水經過(guo)生物(wu)(wu)接觸化池(chi)(chi)處(chu)理(li)(li)后出水自流入二(er)沉(chen)(chen)(chen)池(chi)(chi),以步沉(chen)(chen)(chen)淀(dian)去除脫落的生物(wu)(wu)膜(mo)和部(bu)份有機及無機小顆粒,沉(chen)(chen)(chen)淀(dian)池(chi)(chi)是根據重力(li)作用(yong)的原理(li)(li),當含(han)有懸浮物(wu)(wu)的污(wu)(wu)水從下(xia)往上流動時(shi),由(you)重力(li)作用(yong),將物(wu)(wu)質沉(chen)(chen)(chen)淀(dian)下(xia)來。經過(guo)二(er)沉(chen)(chen)(chen)池(chi)(chi)沉(chen)(chen)(chen)淀(dian)后的出水更清(qing)澈透明。二(er)沉(chen)(chen)(chen)池(chi)(chi)為豎流式沉(chen)(chen)(chen)淀(dian)池(chi)(chi),采用(yong)污(wu)(wu)泥泵定期(qi)提泥氣提污(wu)(wu)泥化池(chi)(chi)內。經過(guo)沉(chen)(chen)(chen)淀(dian)后的處(chu)理(li)(li)水入后續處(chu)理(li)(li)設備。
池(chi):污(wu)水經沉(chen)(chen)淀后,及(ji)大腸(chang)桿指標仍末達到排(pai)放(fang),為(wei)了(le)滅及(ji)大腸(chang)桿,投(tou)加氯片劑(ji)行(xing)處(chu)(chu)理(li)(li),采用(yong)折(zhe)板形(xing)式依靠自身重力,直接排(pai)放(fang)附(fu)近(jin)市政管道(dao)。污(wu)泥(ni)化池(chi):沉(chen)(chen)淀池(chi)所排(pai)放(fang)剩余污(wu)泥(ni)在(zai)池(chi)中(zhong)行(xing)好(hao)(hao)化穩定(ding)(ding)(ding)處(chu)(chu)理(li)(li),以(yi)減少污(wu)泥(ni)的體(ti)積和提高(gao)污(wu)泥(ni)的穩定(ding)(ding)(ding)性。好(hao)(hao)化后的污(wu)泥(ni)量較(jiao)少,定(ding)(ding)(ding)期聯系由(you)環衛部(bu)門抽泥(ni)車清(qing)除外運或行(xing)污(wu)泥(ni)脫水處(chu)(chu)理(li)(li)外運。上(shang)清(qing)液(ye)采用(yong)上(shang)清(qing)液(ye)回流調節池(chi)。
