丽水市水阁污水厂次氯酸钠投加量数据

在污水处理末端消毒工艺中，次氯酸钠投加量是控制余氯浓度与消毒效能的核心命脉。其水解生成的次氯酸（HClO）通过强氧化作用灭活病原微生物，并直接决定出水余氯水平。投加量需精准匹配水质波动：不足时导致粪大肠菌群等指标超标，引发卫生风险；过量则造成余氯残留（>0.5mg/L），毒害水生生态并生成致癌卤代有机物（如三氯甲烷）。故次氯酸钠投加量实为平衡消毒安全性、生态毒性及合规风险的关键工艺杠杆，本数据能为水厂等相关行业生产中的次氯酸钠投加量提供的数据支持与对比；为千吨水次氯酸钠投加量提供数据依据。丽水市水阁污水厂次氯酸钠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、出厂水余氯、次氯酸钠用量、浓度的值，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“出厂水余氯”满足使用要求的日期，使用要求为：出厂水余氯＞0.1mg/L，计算满足使用要求的日期的千吨水次氯酸钠投加量，千吨水次氯酸钠投加量=次氯酸钠用量*浓度/水量*1000；
3、数据统计：以每次连续一个月的次氯酸钠投加量使用情况，统计出全年不同月份的平均水量、平均千吨水次氯酸钠投加量区间；
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次氯酸钠投加量建议。

In the final disinfection process of wastewater treatment, the dosage of sodium hypochlorite is the core determinant controlling residual chlorine concentration and disinfection efficacy. The hypochlorous acid (HClO) generated through its hydrolysis inactivates pathogenic microorganisms via strong oxidative action, and directly determines the effluent residual chlorine level. The dosage must be precisely matched to water quality fluctuations: insufficient dosage will lead to exceeding standard limits for indicators such as fecal coliforms, triggering health risks; excessive dosage will result in residual chlorine (>0.5 mg/L), which is toxic to aquatic ecosystems and generates carcinogenic halogenated organic compounds (e.g., chloroform). Therefore, the sodium hypochlorite dosage is a key process lever for balancing disinfection safety, ecological toxicity and compliance risks. This dataset provides data support and comparison for sodium hypochlorite dosage in production at water treatment plants and related industries, as well as data basis for determining sodium hypochlorite dosage per thousand tons of water.

The data algorithm for sodium hypochlorite dosage at Shuige Wastewater Treatment Plant in Lishui City includes the following steps:
1. Data Collection: Collect daily values of water volume, effluent residual chlorine, sodium hypochlorite dosage and concentration at Shuige Wastewater Treatment Plant in Lishui City over a continuous 12-month period.
2. Data Processing: Screen the collected data to retain dates where the "effluent residual chlorine" meets the usage requirement, i.e., effluent residual chlorine > 0.1 mg/L. Calculate the sodium hypochlorite dosage per thousand tons of water for the retained dates using the formula: Sodium hypochlorite dosage per thousand tons of water = (Sodium hypochlorite dosage × Concentration) / Water volume × 1000.
3. Data Statistics: Using the sodium hypochlorite dosage data of each consecutive one-month period, calculate the average water volume and the average sodium hypochlorite dosage range per thousand tons of water for each month across the whole year.
4. Data Application: Based on the average monthly water volume ranges throughout the year, combined with the impact of special local weather events on water consumption in the current year, provide reasonable recommendations for sodium hypochlorite dosage per thousand tons of water for water treatment plants and related industries.
