污水由許多類別,相應地減少污水對環境的影響也有許多技術和工藝。按照污水來源,污水可分為四類。
一、工業廢水 來自制造采礦和工業生產活動的污水,包括來自與工業或者商業儲藏、加工的徑流活滲瀝液,以及其它不是生活污水的廢水。
二、生活污水 來自住宅、寫字樓、機關或相類似的污水;衛生污水;下水道污水,包括下水道系統中生活污水中混合的工業廢水。
三、商業污水 來自商業設施而且某些成分超過生活污水的無毒、無害的污水。如餐飲污水。洗衣房污水、動物飼養污水,發廊產生的污水等。
四、表面徑流 來自雨水、雪水、高速公路下水,來自城市和工業地區的水等等,表面徑流沒有滲進土壤,沿街道和陸地進入地下水。

4、 Surface runoff comes from rainwater, snow water, highway water, water from urban and industrial areas, etc. surface runoff does not penetrate into soil and enters groundwater along streets and land.
