[0050] In order to verify the dissolved oxygen (DO) and chemical oxygen demand (COD) in urban surface water detected in this method cr ), ammonia nitrogen (NH 3 -N) and total phosphorus (TP) can accurately reflect the surface water quality of the city, the following analysis test is carried out:

[0051] Scheme 1. Analyze 21 indicators in the table of "Environmental Quality Standards for Surface Water" (GB3838-2002) except water temperature, TN, and fecal coliform bacteria;

[0052] Scheme 2. Analysis of the main excessive factors DO, CODcr, NH in the surface water quality of major cities in my country 3 -N, TP, TN5 indicators;

[0053] Scheme 3. Analysis of DO and COD determined in the invention cr , NH 3 -N and TP;

[0054] The specific analysis process is to collect surface water samples of 11 typical cities in my country (A, B, C in the central region, D, E, F in the western region, H, I in the northeast region, J, K, L in the eastern region), and use Three evaluation...

Abstract

The invention provides an urban surface water quality analysis method. The method comprises the first step of presetting a water quality monitoring strategy and determining a monitoring site of surface water in each city according to the water quality monitoring strategy; the second step of detecting dissolved oxygen, chemical oxygen demand, ammonia and nitrogen and total phosphorus contained in unit volume water at each monitoring site and using four detection results as water quality data of the monitoring site; the third step of summarizing the water quality data of the monitoring site of each city and analyzing the water quality data of each city through a Nemerow index method to obtain a water pollution index of the city. According to the method, it is only needed to monitor the four indexes of dissolved oxygen, chemical oxygen demand, ammonia and nitrogen and total phosphorus in the urban surface water, and then the pollution conditions of the urban surface water can be evaluated. The urban surface water quality analysis method has a unified standard and is high in operability.

Description

technical field [0001] The invention belongs to the field of surface water, in particular to a method for analyzing the quality of urban surface water. Background technique [0002] With the continuous advancement of urbanization and industrialization in my country, the urban population and scale have increased sharply, urban water pollution has continued to intensify, and the urban water environment has continued to deteriorate. The problem of urban water environment has become a new challenge in the process of rapid urban development. Strengthening urban water pollution It is imminent to control and improve the quality of urban water environment. [0003] In the process of urban water environment comprehensive management, water quality evaluation is a basic work. Objective evaluation results depend on a scientific evaluation system. To realize the popularization and application of water quality evaluation methods, water quality evaluation methods should have the characteri...
