丽水市水阁污水厂碳源投加量数据

在污水脱氮除磷工艺中，碳源的精准投加是保障总氮（TN）高效去除的核心调控手段。作为反硝化菌的关键电子供体，碳源直接驱动硝酸盐还原为氮气（NO₃⁻→N₂），解决低碳氮比污水脱氮瓶颈；同时为聚磷菌提供厌氧释磷能量，强化生物除磷效能。其投加量需严格匹配进水TN负荷：不足时反硝化受阻，出水总氮超标且二沉池易浮泥；过量则徒增出水COD风险与污泥产量，破坏系统平衡。因此，千吨水碳源投加量是平衡脱氮效率、除磷稳定性与运行经济性的决定性工艺参数，本数据能为水厂等相关行业生产中的碳源投加量提供的数据支持与对比；为千吨水碳源投加量提供数据依据。丽水市水阁污水厂碳源投加量数据算法包括以下步骤：
1、数据采集：采集每天丽水市水阁污水厂的水量、进水COD、进水总氮、出水COD、出水总氮、1#生物池进水投加点碳源用量、2#生物池进水投加点碳源用量、1#生物池三级区投加点碳源用量、2#生物池三级区投加点碳源用量的值，持续以年为单位的时间；
2、数据处理：在采集到的数据中筛选出“出水COD”、“出水总氮”满足使用要求的日期，使用要求为：出水COD＜30mg/L，出水总氮＜10mg/L，计算满足使用要求的日期的千吨水碳源投加量，千吨水碳源投加量=（1#生物池进水投加点碳源用量+2#生物池进水投加点碳源用量+1#生物池三级区投加点碳源用量+2#生物池三级区投加点碳源用量）/水量*1000；
3、数据统计：以每次连续一个月的碳源投加量使用情况，统计出全年不同月份的平均水量、平均千吨水碳源投加量区间；
4、数据应用：根据全年不同月份的平均水量区间，结合当年特殊天气对用水的影响程度，为水厂等相关行业提供合理的千吨水碳源投加量建议。

In the sewage denitrification and dephosphorization process, precise carbon source dosage is the core regulatory measure to ensure efficient total nitrogen (TN) removal. As a key electron donor for denitrifying bacteria, carbon sources directly drive the reduction of nitrate to nitrogen gas (NO₃⁻→N₂), addressing the denitrification bottleneck of sewage with low carbon-to-nitrogen (C/N) ratio; meanwhile, they provide anaerobic phosphorus release energy for polyphosphate-accumulating organisms (PAOs), enhancing the efficiency of biological phosphorus removal. Its dosage must strictly match the influent TN load: insufficient dosage will hinder denitrification, leading to excessive effluent total nitrogen and frequent floating sludge in the secondary sedimentation tank; excessive dosage will unnecessarily increase the effluent COD risk and sludge production, disrupting the system balance. Therefore, the carbon source dosage per thousand tons of water is a decisive process parameter that balances denitrification efficiency, phosphorus removal stability and operational economy. This dataset can provide data support and comparison for carbon source dosage in production of water treatment plants and related industries, and offer data basis for determining carbon source dosage per thousand tons of water.

The carbon source dosage dataset of Shuige Sewage Treatment Plant in Lishui City includes the following steps:
1. Data collection: Collect daily data including water volume, influent COD, influent total nitrogen, effluent COD, effluent total nitrogen, carbon source dosage at the influent dosing points of 1# Biological Tank and 2# Biological Tank, and carbon source dosage at the tertiary zone dosing points of 1# Biological Tank and 2# Biological Tank, for a continuous one-year period.
2. Data processing: Screen the collected data to retain dates where effluent COD < 30 mg/L and effluent total nitrogen < 10 mg/L that meet the usage requirements. Calculate the carbon source dosage per thousand tons of water for the retained dates using the formula: Carbon source dosage per thousand tons of water = (carbon source dosage at influent dosing point of 1# Biological Tank + carbon source dosage at influent dosing point of 2# Biological Tank + carbon source dosage at tertiary zone dosing point of 1# Biological Tank + carbon source dosage at tertiary zone dosing point of 2# Biological Tank) / water volume × 1000.
3. Data statistics: Based on the carbon source dosage usage of each consecutive one-month period, calculate the average water volume and average carbon source dosage interval per thousand tons of water for each month across the full year.
4. Data application: According to the average water volume intervals for different months throughout the year, combined with the impact of special weather in the current year on water consumption, provide reasonable suggestions on carbon source dosage per thousand tons of water for water treatment plants and related industries.
