In order to understand the influence of flocculation on sludge dewatering performance in recent ten years ・ Taking SCI periodicals collected by the Web of Science from 2011 to 2022 as data sources, using the visual analysis tool CiteSpace to draw a map for analysis・ The results showed that the number of articles published and cited in this field had increased year by year in recent ten years, and China was in the leading position. China Academy of Sciences, Tongji University were among the top publishing organizations ・ The research in this field was mainly published in high-level journals such as Bioresource Technology and Water Research ・ The research focused on the influence of flocculation on the dewatering performance of activated sludge,让s mechanism and practical application・ The combined treatment technology with multiple sludge dewatering methods will be a hot research direction in the future・ This paper summarized the research status and hot topics of flocculation to improve sludge dewatering performance, and provided ideas for future research.

Yidonglinchang Gold Polymetallic Deposit occurs in intermediate acid volcanic-subvolcanic rocks of the Ningyuancun Formation.The ore types are mainly carbonate quartz veins and silicified breccia, and the ore-forming geological body is diorite porphyrite and dacite porphyrite.The metallic minerals in the ore are electrum, argentite, native silver, pyrite, chalcopyrite, sphalerite, galena, and so on.The minerals containing gold and silver are mainly electrum, argentite, and native silver.The gangue minerals mainly include quartz, calcite, plagioclase, sericite, and minor content of gypsum.Major ore textures are euhedral-subhedral-anhedral texture, cataclastic texture, metasomatic texture, and inclusion texture.Major ore structures are colloform structure, cavernous structure, comb structure, crystal cluster structure, sparsely disseminated structure, dense massive structure, breccia structure, stockwork structure, and blade structure.The wall rock alteration includes silicification, carbonation, sericitization, clayization, chloritization, and epidotization.With the ore body as the center, a typical epithermal alteration belt is developed from the inside out: silicification zone, beresitization zone, argillation zone, and propylitization zone, generally taking the form of rings.Based on typical deposit analysis, the study takes the volcano-subvolcanic rocks in the Ningyuancun Formation, strong silicification, carbonation, and quartz veins, NEE and near-EW faults, Au, Ag, As, and Sb combination anomalies, low polarization high resistivity, and negative magnetic anomaly as important prospecting indicators in Yidonglinchang Gold Polymetallic Deposit.
