Gongye shui chuli, 2022 采用厌氧交替好氧（A/O）模式下运行的SBR反应器，考察低耗（DO=1.0 mg/L）条件下不同进水m（COD）/m（P）（记作C/P）对主流强化生物除磷（Enhanced biological phosphorus removal，EBPR）系统脱氮除磷效果及其相应的厌氧磷回收性能的影响。结果表明，当进水P浓度保持不变，C/P逐步降低（C/P=400/8、350/8、300/8）时，系统厌氧末期释磷量随进水碳源浓度的降低而逐步减小，相应的侧流磷回收率从61.5%降至45.3 ...

Functional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Dimensional Assembly Engineering of Ce‐MOF Interfaces for Selective Recognition of Phytic Acid
Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Selective molecular recognition is central to chemical sensing yet discriminating structurally similar molecules at complex interfaces remains challenging. Traditional strategies based on tuning size, charge, or binding‐site chemistry often suffer from limited flexibility.

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Efficient and durable bifunctional electrocatalysts are vital for scalable water electrolysis. Here, we realize cobalt‐vacancy (Covac) engineering in CoFeP supported on N,P‐codoped carbon nanocages (Co1‐vacFeP/NPC) through a simple route comprising a CoFe Prussian blue analog precursor, phosphidation–pyrolysis, tannic‐acid etching, and a ...

Gongye shui chuli, 2023 采用厌氧-好氧间歇运行模式，在SBR反应器中分别以丙酸钠、乙酸钠、葡萄糖、蔗糖为单一碳源对生物除磷颗粒污泥进行培养驯化，并考察不同碳源下除磷颗粒污泥对水中磷的去除效果，同时结合高通量测序，探究不同碳源驯化的生物除磷颗粒污泥中微生物种群结构的变化情况。结果证明：碳源为丙酸钠时，系统对磷的去除效果最佳。高通量测序结果表明：碳源对除磷颗粒污泥的微生物种群结构影响显著，以丙酸钠为碳源的颗粒污泥中聚磷菌（PAOs）占比最高；以乙酸钠为碳源的颗粒污泥聚糖菌（GAOs）占比最高；以蔗糖为碳源的颗粒污泥PAOs含量最低，

Gongye shui chuli, 2019 针对石灰除磷工艺产生的污泥量大、污泥处置费用高的现状，介绍了一种以酸洗磷化废水中的主要污染物组分铁盐为除磷试剂的新型除磷工艺，该除磷工艺在未投加除磷药剂的情况下达到了除磷的目的，实现了污染物的内源消化。与石灰除磷工艺相比，新型除磷工艺产生的污泥量减少了30%，有效地减少了企业的污泥处置费用。

四川大学学报. 自然科学版, 2002 小型月牙藻、普通小球藻、斜生栅藻在高磷浓度下的去除磷的能力小于其在较低磷浓度下的除磷能力,而沙角衣藻在不同磷浓度下的除磷的效果则与其它3种藻相反;而从去除磷率来看,其能力大小依次为:沙角衣藻、斜生栅藻、小型月牙藻和普通小球藻.藻类去除磷能力的大小是由单个细胞除磷量和藻体生物量共同决定的.

Gongye shui chuli, 2006 以生活污水二级生物处理后的出水为研究对象，考察了聚合硫酸铁(PFS)及聚合氯化铝(PAC)对初始质量浓度在1～6.5mg/L范围内的总磷的混凝去除效果及影响因素。小试结果表明，PFS与PAC除磷的最佳pH范围分别为7.5～8和8～9；当总磷初始质量浓度较低时，宜采用铁盐除磷。PAC除磷效果受pH影响较大，对初始质量浓度较高的总磷，在碱性条件下宜采用PAC混凝除磷。示范工程应用结果表明，当生物处理后出水总磷质量浓度在1.09～2.4mg/L范围内时，投加聚合硫酸铁质量浓度为10mg/L ...
