锌对EBPR系统除磷性能的影响及其机制

Gongye shui chuli, 2020
强化生物除磷（EBPR）系统具有优良的除磷性能且在水处理领域应用较广。Zn2+是水体中广泛存在的金属离子，其对EBPR系统除磷性能的影响及其机制尚不清楚。为此，构建EBPR系统研究了Zn2+对该系统除磷性能的影响。研究发现，3~100 mg/L的Zn2+对EBPR系统除磷抑制率为2.06%~98.05%。进一步研究Zn2+对代谢中间产物及关键酶活性的影响，发现较高浓度Zn2+（≥10 mg/L）可抑制聚磷微生物体内聚羟基烷酸酯与糖原的正常代谢（p < 0.05），除磷关键酶活性也受到抑制（p ...

Monitoring pH and electric conductivity in an EBPR sequencing batch reactor

Water Science and Technology, 2004
This paper presents laboratory-scale experimentation carried out to study enhanced biological phosphorus removal. Two anaerobic aerobic (A/O) sequencing batch reactors (SBR) have been operated during more than one year to investigate the information provided by monitoring pH and electric conductivity under stationary and transient conditions ...

Layered Extraction and Adsorption Performance of Extracellular Polymeric Substances from Activated Sludge in the Enhanced Biological Phosphorus Removal Process

Molecules, 2019
A large amount of phosphorus was found in the extracellular polymeric substances (EPS) of activated sludge used in enhanced biological phosphorus removal (EBPR), so the role of EPS and extracellular phosphorus in EBPR should not be neglected.

Effect of granular matrix on functional flora in EBPR system

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Enhanced biological phosphorus removal (EBPR) is a very mature phosphorus removal technology, but there is still a problem of unstable treatment effect in the operation of actual wastewater treatment plants, so the study on the effect of phosphorus removal performance still needs to be further studied. Because there are a lot of

Coming to Terms: The Mechanisms of Overplus and Luxury Phosphorus Uptake for Polyphosphate Storage in Microalgae and Yeast

Biotechnology and Bioengineering, Volume 122, Issue 12, Page 3486-3495, December 2025.
Plouviez et al. give a perspective on the terminology used for describing the mechanisms of polyphosphate accumulation in microalgae and yeast. Their differentiation of mechanisms is based on environmental P availability, polyP chemistry, genetics, or cellular function as described in recent literature.

Phosphorus Plant Availability of Biochars Derived From Contrasting Sewage Sludges to Ryegrass

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 6, Page 1027-1035, December 2025.
ABSTRACT Background Although phosphorus (P) is an essential element for human life, it is currently sourced unsustainably primarily from non‐renewable phosphate rock sources. Sewage sludge pyrolysis is a method that concentrates nutrients in sludge, a large renewable P source, to produce a sustainable phosphorus fertilizer.

Metabolic Differentiation of Co-occurring Accumulibacter Clades Revealed through Genome-Resolved Metatranscriptomics

mSystems, 2021
Natural microbial communities consist of closely related taxa that may exhibit phenotypic differences and inhabit distinct niches. However, connecting genetic diversity to ecological properties remains a challenge in microbial ecology due to the lack of ...
