Addressing the complexity and uncertainty of township wastewater treatment, this paper systematically reviews innovative applications of artificial intelligence in pollutant removal, real-time monitoring, and process optimization. Considering the challenges of large fluctuations in flow and water quality, high nitrogen and phosphorus loads, and pronounced seasonal variability in township wastewater, we propose a technical route centered on supervised and unsupervised learning: regression and classification models for predicting and classifying key indicators such as COD, ammonia nitrogen, total nitrogen, and total phosphorus; clustering, anomaly detection, and dimensionality reduction for condition identification, shock load early warning, and visualization; and feature engineering enhanced by regularization and ensemble methods to improve generalization under small-sample and imbalanced settings. For field deployment, data governance and interpretability are critical enablers: a standardized pipeline of acquisition, cleaning, transformation, feature selection, and dimensionality reduction builds a high-quality data foundation; K-means, DBSCAN, PCA, and related methods underpin real-time monitoring, maintenance closed loops, and operator interpretability; explainable AI with SHAP and partial dependence plots complements white-box models and rule bases to meet regulatory traceability. Meanwhile, this paper proposes a governance framework from an ethical and forward-looking perspective: ensuring sustainable applications through model transparency, accountability mechanisms, and full life-cycle environmental footprint assessment; and bridging urban-rural disparities through data fairness and privacy-preserving governance. Looking to the medium and long term, we advocate for hybrid modeling that deeply integrates data-driven and mechanistic models to enhance the
