- 摘要:
- 住宅区化粪池排放的H2S是引起社区恶臭污染和投诉的重要原因。选取某住宅区,对化粪池排放气体的流量、H2S浓度、污水水质与流速等指标进行了连续监测,并分析了H2S排放量和相关影响因素。结果表明,该住宅区每月测得的化粪池H2S排放浓度范围为(69.9±25.4) mg/m3,并呈现出夏季高、冬季低的特点。污水pH、氧化还原电位(ORP)和硫酸盐与每月监测的H2S排放浓度呈显著负相关,而气温、湿度、水温、COD和硫化物浓度与H2S排放浓度呈显著正相关。测定了6月某天化粪池H2S排放浓度随时间的变化,发现在居民用餐和洗漱时间段内H2S排放浓度出现明显峰值,污水流速与H2S排放浓度的Pearson相关系数R值为0.32,呈显著相关关系。该住宅区化粪池全年人均H2S排放量为2.34×10-3 kg,据此估算出北京市住宅区化粪池H2S的年排放总量为51.3 t。
- Abstract:
- H2S emission from septic tanks in residential areas is an important cause of odor pollution and complaints in communities. In this study, a residential area was selected and the septic tanks emissions flow rate, H2S concentration, influent quality and flow rate were continuously monitored, and H2S emissions and related influencing factors were analyzed. The results showed that the monthly measured septic tanks H2S emission concentrations in this residential area were (69.9 ± 25.4) mg/m3 and showed a pattern of high in summer and low in winter. Influent pH, oxidation reduction potential (ORP), and sulfate were significantly negatively correlated with monthly monitored H2S emission concentrations, while air temperature, humidity, water temperature, COD, and sulfide concentrations were significantly positively correlated with H2S emission concentrations. The variation of septic tanks H2S emission concentration with time was measured on a day in June, and it was found that there was a significant peak of H2S emission concentration during the time of meal and wash for residents, and the Pearson correlation coefficient R value of 0.32 between sewage flow rate and H2S emission concentration was significantly correlated. The annual per capita H2S emission from septic tanks in this residential area was 2.34×10-3 kg, and the total annual emission of H2S from septic tanks in residential areas in Beijing City was estimated to be 51.3 t.
