To valorise winery treated wastewater and to produce suitable water for the irrigation of vineyards, or other factory operations, the WETWINE project set up a combination of a hydrolytic up-flow sludge blanket (HUSB) reactor and constructed wetlands (CW). The WETWINE plant is located in Tomiño (Pontevedra, Spain) and is being validated at the demo-scale at Santiago Ruiz Winery (NW Spain). The plant consisted of a HUSB reactor for removing suspended solids and hydrolyse organic matter, followed by two vertical subsurface flow constructed wetland (VF) operating in parallel and to provide further treatment, a horizontal subsurface flow constructed wetland (HF) operating in series. After two years of continuous monitoring and regardless in the variation of flow and load, the hybrid system achieved average removal efficiencies of over 93% for total suspended solids and chemical oxygen demand, receiving an overall surface loading of up to 115 g COD/m²·d. Total nitrogen removal reached 62% with an average concertation of 21 mg N/ L. The WETWINE plant was also able to increased the pH in the effluent from 5.5 at the influent to 7.2.

为了使酿酒厂处理过的废水增值，并为葡萄园灌溉或其他工厂运营生产合适的水，WETWINE 项目建立了一个水解上流式污泥床 (HUSB) 反应器和人工湿地 (CW) 的组合。WETWINE 工厂位于托米尼奥（西班牙蓬特韦德拉），正在圣地亚哥鲁伊斯酒厂（西班牙西北部）进行规模验证。该工厂包括一个 HUSB 反应器，用于去除悬浮固体和水解有机物，然后是两个平行运行的垂直地下流人工湿地 (VF) 并提供进一步处理，一个水平地下流人工湿地 (HF) 串联运行。经过两年的持续监测，无论流量和负荷如何变化，² ·d。总氮去除率达到 62%，平均浓度为 21 mg N/L。WETWINE 工厂还能够将出水的 pH 值从进水处的 5.5 提高到 7.2。
