Every day, a large amount of wastewater is discharged directly or indirectly into the environment without any treatment, dissolved ions, nutrients (N, P), sulfates, chlorides, residual chlorine, metals heavy, organic compounds, grease, pathogenic microorganisms,... seriously pollute water sources. The first consequence is causing ecological imbalance, some species of organisms become extinct because they do not adapt to polluted water, next is the effect on us humans. Contaminated water causes diseases: dermatology, intestinal ... and moreover diseases that the world has no cure for such as cancer... The article introduces the results of analysis and assessment of the content of indicators total phosphorus, phosphate, total nitrogen, ammonium, chloride, residual chlorine, color, pH, total solids in water of some rivers and lakes in Bac Tu Liem District, Hanoi. Analytical results show that: pH = 6.13 - 6.62
color degree: 11.44 - 27.13mg/l Pt
turbidity: 11.00-30.00 NTU
total solids: 35.13- 80.21mg/l
COD: 81.350 - 151.220mg/l
total Nitrogen: 3.780 – 26.790mg/l
Ammonium: 0.066 -12.525mg/l
total phosphorus: 0.078 - 1,080mg/l
Phosphate: 0.016- 0.665mg/l
Chloride: 10.813 - 13.472mg/l
residual chlorine: 0.300 - 27.300mg/l. At some survey points, COD, ammonium, and turbidity levels exceeded the allowable limits according to QCVN 08-MT: 2015/BTNMT.Hàng ngày, một lượng lớn nước thải được xả trực tiếp hoặc gián tiếp ra ngoài môi trường mà chưa qua xử lý, các ion hòa tan, các chất dinh dưỡng (N, P), sunfat, Clorua, Clo dư, các kim loại nặng, các hợp chất hữu cơ dầu mỡ, các vi sinh vật gây bệnh,… gây ô nhiễm nghiêm trọng nguồn nước.
