Irrigation with Treated Sewage Effluentswerage systems in the nineteenth century, sewage (domestic wastewater) was used at “sewage farms”, and by 1900 there were numerous sewage farms in Europe and in the United States (Reed and Crites 1984; Sterritt and Lester 1988). Although these sewage farms were used primarily for waste disposal, inc作者: kidney 時(shí)間: 2025-3-24 09:00

However, this practice has limitations for the disposal of subsurface drainage, which contains not only accretions of dissolved salts but a作者: 積習(xí)難改 時(shí)間: 2025-3-24 11:43
