Environmental monitoring plan: make a campus water environment monitoring plan.

Formulation of environmental monitoring plan

Pollution source investigation: water pollution source

Sewage discharge summary

Solid waste pollution source (1) domestic waste

According to the investigation, the solid waste of domestic garbage around the proposed project area mainly comes from the domestic garbage generated by residents within the planned scope of the project and around it.

(2) Solid waste: mainly a small amount of domestic waste and a small amount of agricultural waste, which has little impact on the environment.

Air environment: Tokyo Avenue is in the south of this project, and road dust and automobile exhaust are the main air pollution sources. But there are 50~ 100 meters of green buffer zones on both sides of the highway, which can protect the surrounding rings.

The environmental impact is not great.

The source, quantity, fuel type, pollutant name and emission mode of campus air pollutants provide the basis for the selection of atmospheric environmental monitoring projects.

1, layout of surface water environment monitoring section (1)

According to the hydrological, climatic, geological and geomorphological data of the water body of this project. Such as the changes of water level, water quantity, flow velocity and direction, the width and depth of the river, the present situation and utilization of water resources along the water body, the distribution of drinking water sources and key water source protection areas, etc.

Because the width of the water surface is less than or equal to 50 meters, there is a (middle vertical line) and the layout of the vertical line on the section should avoid the pollution zone on the shore. If the water depth is less than 5 meters, set a point (0.5 meters below the water surface).

According to the characteristics of water pollution and the distribution of surface water in the project area, there are 6 monitoring sections in the evaluation area.

(2) Monitoring items

Flow rate, flow rate, water temperature (℃), pH value, petroleum, ammonia nitrogen, total nitrogen, BOD 5, COD Cr, dissolved oxygen, permanganate index, total phosphorus, fecal coliform, copper, lead, zinc and hexavalent chromium.

(2) Sampling time and frequency

The monitoring period is the first stage (dry season), with continuous sampling for three days. (3) Analysis method.

Sampling and monitoring methods are in accordance with Technical Specifications for Surface Water and Sewage Monitoring (HJ/T 9 1-2002) and Practical Analysis Methods for Surface Water Environmental Quality Monitoring. (4) Environmental quality assessment of surface water.

According to the test results, some indexes of 6 sections exceeded the standard, mainly BOD 5, CODcr and TP. In addition, the anionic surfactant at the junction of Beishahe and Baojing Line also exceeded the standard. Judging from the over-standard water quality indicators, the main reasons for the water quality of Dongsha River and Beisha River should come from domestic pollution sources, and the treatment of domestic sewage along the river should be strengthened.

2, atmospheric environmental quality monitoring scheme

(1) air environment analysis and screening of monitoring factors

According to the national environmental air quality standards and the discharge of air pollutants around the campus, the monitoring items are screened; Emission of uncharacteristic pollutants in our school. According to the investigation results of atmospheric pollution sources, TSP, PM 10, SO 2, NO 2 and CO can be selected as atmospheric environmental monitoring items.

(2) Layout of sampling points

According to the discharge standard of pollutants, combined with the requirements of various environmental functional zones on campus, as well as the local topography, geomorphology and meteorological conditions, the sampling points are arranged by combining functional zone distribution method and grid distribution method. The name of each monitoring point, azimuth and linear distance from the campus center can be listed in Table 4, and the specific location of each monitoring point should be indicated on the general plan.

Table 4 Name and relative orientation of measuring points

(3) Determination of monitoring items and analysis methods

The monitoring items determined according to the screening results of atmospheric environmental monitoring factors shall be implemented in accordance with the sampling and analysis methods specified in Methods for Monitoring and Analysis of Air and Waste Gas, Technical Specifications for Environmental Monitoring and Environmental Air Quality Standard. See Table 5 for specific methods.

Table 5 Monitoring Items and Analysis Methods of Ambient Air

(4) data collation

The original data of monitoring results should be correctly written in accordance with the retention rules of effective figures, and the operation of monitoring data should follow the operating rules. In data processing, we should first find out the reasons of suspicious data technically, and then carry out statistical inspection. Data that have been verified as abnormal values should be excluded to make the determination results more realistic. (5) Atmospheric monitoring results and analysis

After the sample is collected, it shall be analyzed as required immediately, and the analysis results shall be processed.

(6) Evaluation of campus air quality

Compare the campus air quality with the corresponding national standards and draw a conclusion; Analyze the present situation of campus air quality. Find out the reasons for the present situation of campus air quality; Predict the quality of campus air environment in the next two years; Suggestions and measures are put forward to improve the quality of campus air environment.

1, layout of acoustic environmental quality monitoring (1)

According to the technical principles and methods of Technical Guidelines for Environmental Impact Assessment-Acoustic Environment, monitoring points are set up. Within the scope of evaluation, the environmental status of four typical points is monitored, of which 1 is the traffic noise monitoring point, and 2, 3 and 4 are the noise monitoring points within one meter outside the boundary of the proposed project. The specific monitoring points are shown in the figure.

(2) Monitoring items and frequency

Monitoring items: Day and night equivalent sound level monitoring frequency: 24-hour continuous monitoring (3) sampling method and analysis standard.

The monitoring method shall be carried out according to the conditions specified in Technical Specification for Environmental Monitoring, and the traffic volume shall be counted synchronously.

(4) Evaluation criteria and tools used

The project area belongs to the residential, cultural and educational institutions, and belongs to the 1 noise functional area. The regional environmental noise is subject to the 1 standard in the Quality Standard for Acoustic Environment (GB3096-2008), that is, 55dB (A) in the daytime and 45dB (A) at night (4a regional standard is implemented on both sides of the main traffic road, that is, 74A in the daytime).

2. Acoustic environmental quality assessment.

According to the statistical results of environmental noise monitoring, in terms of regional noise, the daytime sound environment quality is good, and the equivalent continuous A sound level Leq of each monitoring point exceeds the standard by 50% at night, but the exceeding range is not too large, indicating that the nighttime sound environment quality of the project area is damaged to some extent at present.

4. Environmental impact assessment of solid waste

Solid wastes generated during the construction period include waste soil and rocks generated by foundation leveling, construction wastes and domestic wastes of construction workers. Construction waste generated by construction is disposed in low-lying areas of the base without external disposal. However, it is necessary to set up a suitable site for temporary stacking, and remove it in time for landfill disposal and greening treatment, otherwise it will cause soil erosion.

To sum up, there is less solid waste during the construction period, and the influence scope is mainly in the construction area. With the end of the construction area, the influence of solid waste during the construction period disappears, so as long as

By strengthening construction management and taking corresponding measures, the adverse impact of solid waste on the environment during construction can be slowed down or eliminated.
