Feasibility Study On Hash A-C Type Automatic Monitor Ammonia Applied In Industrial Wastewater Ammonia Emissions Accounting

Ammonia monitor from hash AC, fundamentals of the structure, the type of the polluting enterprises ammonia wastewater discharge,24-hour monitoring results to the manual and online data sources, hash AC ammonia monitor used in quality control and data assurance requirements, analysis the feasibility of the total ammonia emissions accounting.Analysis of trends in emissions of manual and hash A-C ammonia monitor on-line monitoring results of flow and concentration-the results of the intercomparison study methods showed that, The main types of typical industry ammonia wastewater discharge:Concentration-based, flow-based and hybrid. Sewage treatment industry, chemical industry, wine is a concentration-oriented, the emissions changes with the concentration, more stable flow, The amount of sewage trend over time and concentration consistent trends over time. The food processing industry, oil processing industry is a hybrid. The volume of sewage trend over time is neither consistent trends over time and concentration, not consistent trends over time and the amount of water. Non-ferrous metal smelting industry belongs to the water leading the volume change with the change of water flow, the emissions trend changes over time and the amount of water consistent trends over time.To the manual hash AC ammonia monitor online ammonia emissions relative error analysis as a starting point, combined with the correction of control sources of pollution monitoring data by the least square method for on-line ammonia nitrogen emissions. Research using hash A-C automatic monitor ammonia monitoring data, Combined with existing statistical methods of calculation of ammonia emissions from enterprises ammonia annual emissions. In order to establish the amount of sewage discharged calculation method based on the continuous automatic monitoring data. The method includes the use of technology for online monitoring data estimates pollutant emissions and the establishment of the audit approach of continuous automatic monitoring data (flow rate, concentration). Ammonia-line annual emissions of six types of industries handmade original emissions relative error in the range of 0.63to10.1%. Comply with (HJ/T354-2007) specified in the relative error of plus or minus15%. This shows that the hash AC ammonia monitor monitoring data used in enterprise wastewater total ammonia emissions accounting is feasible. Hash AC ammonia monitor used in business accounting of the total ammonia emissions can improve the efficiency of the total accounting, human freed from a lot of manual monitoring calculations, To further improve the sustainability of the accounting of total ammonia nitrogen, precision and accuracy.
