5.2 Wastewater discharge monitoring

Monitoring points, monitoring indicators and monitoring frequency of wastewater discharge monitoring are carried out according to Table 3.

Table 3 Minimum monitoring frequency of wastewater monitoring indicators

Boiler or Gas Turbine Scale Fuel Type Monitoring Point Monitoring Index monitor frequency Involving a single 14MW or 20t/h and above the boiler or gas turbine Machine sewage unit Coal Total discharge of wastewater PH, chemical oxygen demand, ammonia nitrogen, suspended solids, total Phosphorus 1, petroleum, fluoride, sulfide, volatile phenol, Soluble total solids (total salt), flow rate Desulfurization wastewater discharge port pH value, total arsenic, total lead, total mercury, total cadmium, flow month Gas enterprise wastewater total discharge pH, chemical oxygen demand, ammonia nitrogen, suspended solids, total Phosphorus 1, total dissolved solids (total salt), flow rate Quarterly Fuel Total discharge of wastewater PH, chemical oxygen demand, ammonia nitrogen, suspended solids, total Phosphorus 1, petroleum, sulfide, dissolved total solids (all Salt), flow Desulfurization wastewater discharge port pH value, total arsenic, total lead, total mercury, total cadmium, flow month all circulating cooling water discharge port pH, chemical oxygen demand, total phosphorus, flow rate quarter all DC cooling water discharge ports Water temperature, flow day Total residual chlorine Winter and summer the prison Measured one Only a single 14MW or 20t/h below the boiler sewage unit all enterprises wastewater total discharge pH, chemical oxygen demand, ammonia nitrogen, suspended solids, flow

Note 1. If the sewage is not discharged into the total discharge, the total phosphorus can not be measured.

Note 2. In addition to desulfurization wastewater, and other industrial wastewater mixed emissions, with reference to the relevant industrial sector monitoring requirements;

, The frequency of monitoring can be performed on a quarterly basis.

5.3 Environmental noise monitoring at the factory boundary

The environmental noise monitoring point setting should be followed in the principle of HJ 819. The main consideration is given in Table 4.

Cloth situation.

Table 4 Noise emissions from the environmental noise distribution at the factory boundary

No. Type of fuel and thermal energy conversion facility Noise emission source Main equipment auxiliary equipment 1 coal-fired boiler generator, steam turbine Induced draft fan, cooling tower, desulfurization tower, feed pump, ash Pump room, crushed coal room, circulating pump room and so on

2 Gas-fueled boilers or gas turbines Gas turbines (internal combustion engines) Cooling towers, compressors, etc.

3 oil-fired boiler or gas turbine steam turbine, generator air compressor, fan, water pump, etc.

Environmental noise at the factory boundary is carried out at least once a day and night, and the monitoring index is equivalent A sound level. Surrounded by sensitive points, should increase the frequency of monitoring.

5.4 Peripheral environmental quality impact monitoring

5.4.1 Environmental impact assessment documents and their approval and other environmental management policies are expressly required and implemented as required.

5.4.2 Where there is no express requirement, the sewage unit of ash (slag) field of coal-fired thermal power plant shall, if it considers it necessary, HJ/T 164 provides groundwater monitoring points. Monitoring indicators for the pH, chemical oxygen demand, sulfide, fluoride, oil Class, total hardness, total mercury, total arsenic, total lead, total cadmium, etc., the frequency of monitoring at least once a year.
