When coal is changed, mercury and its compounds are required to increase the frequency of monitoring. Note 2. the use of liquid ammonia and other ammonia as a reducing agent, remove the flue gas nitrogen oxides, can be selected. Note 3. Boilers or gas turbines for other gas fuels only for purifying natural gas as fuel; Of the boiler or gas turbine. Note 4. briquette, coal-water slurry, coal gangue boiler reference coal-fired boiler; oil shale, petroleum coke, biomass boiler or gas turbine group with reference to oil The boiler or gas turbine. Note 5. A variety of fueled boilers or gas turbines should perform the most stringent monitoring frequency. Note 6. Exhaust gas monitoring should simultaneously monitor flue gas parameters. 5.1.2 Unorganized emissions monitoring points, indicators and frequency Unorganized emissions monitoring points set, monitoring indicators and monitoring frequency according to Table 2 implementation. Table 2 Minimum monitoring frequency of unorganized emissions monitoring indicators Fuel Type Monitoring Point Monitoring Indicator Monitoring Frequency Coal, coal gangue, petroleum coke, oil shale, biomass plant boundary particles 1 quarter Oil and gas storage tank around the factory and non - methane total hydrocarbon quarter All fuel ammonia tank area around the ammonia 2 quarter Note 1. The frequency of monitoring is increased in unclosed yards. Peripheral sensitive, may be appropriate to reduce the frequency of monitoring. Note 2. Applicable to the use of liquid ammonia or ammonia as a reducing agent business. 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.
