AB  - The direct discharge of wastewater can cause severe damage to the water 
      environment of the surface water. However, the influence of dissolved organic 
      matter (DOM) present in wastewater on the allocation of DOM, nitrogen (N), and 
      phosphorus (P) in rivers remains largely unexplored. Addressing the urgent need 
      to monitor areas affected by direct wastewater discharge in a long-term and 
      systematic manner is crucial. In this paper, the DOM of overlying water and 
      sediment in the WWTPs-river-integrated area was characterized by 
      ultraviolet-visible absorption spectroscopy (UV-vis), three-dimensional 
      excitation-emission matrix combined with parallel factor (PARAFAC) method. The 
      effects of WWTPs on receiving waters were investigated, and the potential link 
      between DOM and N, P pollution was explored. The pollution risk was fitted and 
      predicted using a spectral index. The results indicate that the improved water 
      quality index (IWQI) is more suitable for the WWTPs-river integration zone. The 
      DOM fraction in this region is dominated by humic-like matter, which is mainly 
      influenced by WWTPs drainage as well as microbial activities. The DOM fractions 
      in sediment and overlying water were extremely similar, but fluorescence 
      intensity possessed more significant spatial differences. The increase in 
      humic-like matter facilitates the production and preservation of P and also 
      inhibits nitrification, thus affecting the N cycle. There is a significant 
      correlation between DOM fraction, fluorescence index, and N, P. Fluorescence 
      index (FI) fitting of overlying water DOM predicted IWQI and trophic level index, 
      and a(254) fitting of sediment DOM predicted nitrogen and phosphorus pollution 
      risk (FF) with good results. These results contribute to a better understanding 
      of the impact of WWTPs on receiving waters and the potential link between DOM and 
      N and P pollution and provide new ideas for monitoring the water environment in 
      highly polluted areas.
