廢水處理小區是具備一種或多種多樣作用的相對性單獨的地區，包含一般 實際意義上的住戶生活小區、醫院門診、生態公園、度假旅游度假村、在建職教城、高速路的生活高速服務區等，其排水設備一般 沒有城市市政管網覆蓋面積以內，務必設定單獨的廢水處理設備。小區生活污水有別于包含一部分化工廢水的城市廢水，其水體、水流量鐘頭轉變指數很大，空氣污染物濃度值一般 比城市廢水低，廢水可生物化學性好，解決難度系數較小；且因為其環境污染來源于非常簡單，從解決技術性和解決成本費視角考慮到，具備非常的技術性可行性分析和很高的回收利用使用價值。

材料顯示信息，以生活(huo)用(yong)(yong)(yong)水(shui)(shui)為例子，用(yong)(yong)(yong)以烹制、食用(yong)(yong)(yong)的水(shui)(shui)占占5%，而對(dui)占20%～30%不與(yu)身體直接接觸的生活(huo)雜用(yong)(yong)(yong)水(shui)(shui)如沖廁用(yong)(yong)(yong)水(shui)(shui)等，再加(jia)上小區園林綠化灌(guan)溉用(yong)(yong)(yong)水(shui)(shui)、中央(yang)空調冷卻循環水(shui)(shui)、路面沖洗(xi)水(shui)(shui)及其(qi)車子清理(li)等用(yong)(yong)(yong)水(shui)(shui)也可歸(gui)于(yu)生活(huo)雜用(yong)(yong)(yong)水(shui)(shui)的范圍，并(bing)無高水(shui)(shui)體規定，這類用(yong)(yong)(yong)水(shui)(shui)遍布為小區生活(huo)污水(shui)(shui)的回收利用(yong)(yong)(yong)動向出示了很有可能。
