This study innovatively integrates machine vision with image texture analysis to systematically investigate the regulatory mechanisms of coagulant dosage and raw water turbidity on floc size distribution and textural features. A non-invasive high-speed imaging system was employed to capture the entire flocculation dynamics, coupled with Python-OpenCV algorithms for quantitative characterization of floc parameters. Results demonstrate that under constant turbidity: (1) Insufficient coagulant dosage leads to inadequate colloidal destabilization, manifested by reduced floc quantity and significant decreases in image gray mean, entropy, and correlation values; (2) Optimal dosage produces concentrated floc size distribution with low coefficient of variation (CV); (3) Overdosing induces floc erosion and fragmentation, forming bi-/tri-modal distributions with substantially increased CV. Furthermore, high-turbidity raw water exacerbates floc fragmentation, resulting in dispersed size distribution (elevated CV) and enhanced light scattering (improved texture contrast). This work first elucidates the synergistic evolution between image textural features and floc size distribution, confirming their potential as sensitive indicators for real-time coagulant optimization, thereby providing theoretical foundations for intelligent control of coagulation processes.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"199 ","pages":"Article 107298"},"PeriodicalIF":6.9,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This system aims to produce electricity, hydrogen, methane, and methanol while addressing challenges in sustainable energy generation and greenhouse gas emissions reduction. A thermodynamic model evaluates the system’s energy efficiency and performance under varying operating conditions. The PEME unit efficiently produces hydrogen, which is utilized in the synthesis of methane (SNG) and methanol. The SOFC and DMFC units generate electrical power while utilizing methane and methanol as fuels, respectively. Key parameters such as current density, inlet temperature, and methanol concentration are optimized to maximize efficiency and minimize energy losses. Results indicate that the combined system achieves peak energy efficiencies of 41.27 % for SOFC and 20.41 % for DMFC under ideal operating conditions. The integration of renewable wind and biomass resources significantly reduces reliance on fossil fuels, contributing to a substantial decrease in CO₂ emissions. Economic analysis reveals that the system is cost-effective, with total product unit costs ranging between 27.16 $/GJ and 28.41 $/GJ depending on operating parameters.

This paper presents an experimental investigation on the evaluation of strength performance of high-water-content dredged clay treated with ground granulated blast-furnace slag (GGBS) for use as backfilling materials. A series of laboratory tests, including unconfined compressive strength (UCS) tests, direct shear (DS) tests, and scanning electron microscopy (SEM) analysis, were conducted to systematically evaluate the effects of GGBS dosage and curing time on the strength behavior of GGBS-treated dredged clay samples at varying water contents. The UCS test results indicate that all samples exhibited strain-softening behavior, with the unconfined compressive strength initially increasing and then decreasing as the GGBS content increased, peaking at an optimal dosage of 30 %. Additionally, the unconfined compressive strength consistently increased with curing time. A quantitative equation was developed to estimate the unconfined compressive strength of GGBS-stabilized dredged clay, at different curing times and water contents when the GGBS dosage is below 30 %. The DS test results demonstrate that, under a given vertical stress, the shear strength of the samples increases with both GGBS content within 30 % and curing time within 28d. The shear strength parameters, including cohesion and internal friction angle, also increased as the GGBS dosage ranged from 10 % to 30 % and the curing time extended from 3 h to 28d. Two quantitative equations were formulated to respectively estimate the cohesion and internal friction angle of GGBS-stabilized dredged clay samples at various GGBS contents from 10 % to 30 % and curing times 3 h to 28d.

Therefore, by calculating the oil spill area under different water depth (static water), leakage aperture, sea surface wind speed and 0# diesel pipeline flow rate within 0.5–7 s, a total of 686 sets of oil spill area data were generated. Four algorithms, namely BP neural network, genetic algorithm-optimized BP neural network, particle swarm optimization BP neural network and convolutional neural network, were employed to predict the oil spill area, and a prediction model for the oil spill area of submarine pipelines was established. The influencing factors such as water depth, leakage aperture, sea surface wind speed and pipeline flow velocity were used as model inputs, and the output was the prediction result. By comparing the training and validation results of BP,PSO-BP,GA-BP and CNN, it was found that the PSO-improved BP neural network prediction model had a higher prediction accuracy for the oil spill area of submarine pipelines. Compared with the ordinary BP neural network, the RMSE of the test set was reduced by 54 %, and the MAE was reduced by 50.22 %, which basically met the practical application standards.
