不同純生物菌劑對(duì)黑臭水體底泥的處理效果
- Title:
- Treatment Efficiency of Black and Odorous Water Body Sediment with Different Biological Agents
- Keywords:
- black and odorous water body; biodegradation; sediment stabilization; ectopic treatment; microbial community
- 摘要:
- 目前黑臭水體底泥通常采用化學(xué)或生物方法進(jìn)行異位治理，生物法由于簡(jiǎn)單易操作、處理成本較低而被廣泛應(yīng)用，并能夠?yàn)楹罄m(xù)的底泥資源化利用提供條件。為探究更適宜的生物處理方法，明確生物處理過(guò)程中的微生物群落變化規(guī)律，分別采用不同種類的純生物菌劑（硝化細(xì)菌、反硝化細(xì)菌、光合細(xì)菌和芽孢桿菌）對(duì)黑臭水體底泥進(jìn)行異位處理，通過(guò)投加不同劑量的純菌劑，比較反應(yīng)前后底泥中的總氮、總磷、有機(jī)質(zhì)及含水率的變化。結(jié)果表明，在常溫（20±5） ℃下經(jīng)過(guò)30 d的處理，底泥中含水率、總氮和有機(jī)質(zhì)含量都有不同程度的降低。其中，投加量為35 mg/L的反硝化細(xì)菌試驗(yàn)組處理效果最好，總氮和有機(jī)質(zhì)去除率分別達(dá)到59.90%和20.93%。三維熒光光譜分析表明，投加純生物菌劑處理后，底泥中的大分子有機(jī)物濃度降低，小分子物質(zhì)濃度有不同程度的升高，說(shuō)明生物菌劑能夠提高底泥中微生物的活性，不僅促進(jìn)了有機(jī)物的降解，還為反硝化反應(yīng)提供了碳源，促進(jìn)了底泥中總氮的去除。此外，高通量測(cè)序也表明，投加菌劑的試驗(yàn)組樣本中，都出現(xiàn)了一定豐度的Thiobacillus、Sulfurovum、Sulfuricurvum和Sulfurimonas，且在芽孢桿菌試驗(yàn)組和光合細(xì)菌試驗(yàn)組中比例較高，四個(gè)菌屬總比例分別達(dá)到13.24%和14.80%。這四個(gè)菌屬能夠參與硫代謝，對(duì)于底泥中有機(jī)質(zhì)（如蛋白等）的降解起到重要作用。
- Abstract:
- At present, chemical or biological methods are usually employed for ectopic treatment of black and odorous water sediment. Biological method is widely applied because of its simplicity and low treatment cost, and it is beneficial to the subsequent utilization of sediment. In order to investigate a suitable biological treatment process and demonstrate the variations of microbial community during the biological treatment process, four types of biological agents (nitrifying bacteria, denitrifying bacteria, photosynthetic bacteria, and bacillus) were used for ectopic treatment of black and odorous water sediment. Different dosages of biological agents were added, and variations of total nitrogen (TN), total phosphorus, organic matter and water content in the sediment before and after the reaction were compared. After treatment of 30 days at room temperature (20±5) ℃, water content, total nitrogen, and organic matter in the sediment all decreased to different degrees. Among them, the denitrifying bacteria group with dosage of 35 mg/L had the best treatment efficiency: removal efficiencies of total nitrogen and organic matter reached 59.90% and 20.93%, respectively. Three-dimensional fluorescence spectrum analysis showed that the concentration of macromolecular organic matter in the sediment decreased and the concentration of small molecular matter increased in different degree after adding pure biological agent. This indicated that the biological agents improved the activity of microorganisms in the sediment, not only promoting the degradation of organic matter, but also providing carbon source for denitrification and promoting the removal of total nitrogen in the sediment. Furthermore, highthroughput sequencing also showed that Thiobacillus, Sulfurovum, Sulfuricurvum and Sulfurimonas were observed in all experimental groups with addition of biological agents, and the higher proportions in experimental groups with addition of bacillus and photosynthetic bacteria (total proportions of the four genera reaching 13.24% and 14.80%, respectively) were detected. These four genera were related to sulfur metabolism and might play an important role in the degradation of organics, such as proteins, in the sediment.
