Background
The river mouth suspended fine-particle silt is easy to flocculate to form flocs (flocs) or aggregates (aggregates) with different shapes and particle sizes spanning several orders of magnitude (10 < -6 > -10 < -3 > m and possibly larger sea snow). Individual flocks can be viewed as independent micro-ecosystems with abundant moisture and porosity, consisting of inorganic (e.g., clay minerals) and organic (e.g., microorganisms, exopolymers, bacteria) multi-source particles. Under the action of several factors of local physics, chemistry and biology, the flocs are always in the high-frequency change state of coalescence and fragmentation, and their material composition, grain size, effective density and form structure are also continuously regulated. The essential characteristics of multi-process participation and multi-factor influence bring great challenges to flocculation in-situ observation and interdisciplinary research; nevertheless, flocculation is always the basic process which cannot be avoided in the research of fine-particle silt, and the flocculation has very important significance in the basic problem layers of silt transportation and sedimentation, element and nutrient salt circulation, pollutant migration and diffusion and the like at the river mouth.
The undisturbed in-situ observation of the flocs is always a technical bottleneck for the flocculation research of the viscous silt. Currently, there are three main observation modes: a laser diffraction system, a photographing/imaging system, and an acoustic signal conversion method. However, the results of field observation are influenced by various factors, and it is difficult to mechanistically discuss the basic process of flocculation. Therefore, the experimental device for flocculation of the fine-particle viscous silt is designed and manufactured, the influence of various single physical, chemical and biological factors or the composite action of the factors on flocculation is considered under the action of ideal isotropic turbulence, the basic process and mechanism of flocculation can be deeply disclosed, and beneficial guidance is provided for field observation and population balance simulation of flocculation.
