The invention discloses an urban
river water environment treatment method. Water in a riverway is isolated by using a water-stop wall and a soil-retaining
pile along a riverbank
retaining wall in theriverway to form a near-
shore zone, and the near-
shore zone has all functions of intercepting main pipes and collecting pollutants entering the riverway; the near-
shore zone is divided into an ecological
shallow water area and a local
deep water area. River
sludge and biological filler are filled in the ecological
shallow water area, and aquatic plants are planted on the biological filler layer, so that all functions of purifying
water quality, beautifying landscape and the like of the ecological
floating island can be realized; the local
deep water area is arranged at a river inlet, filled with river
silt and covered with a biological filler, and the water bottom elevation is lower than that of the river inlet;
sewage lifting pumps are arranged in the near-
shore zone at fixed points, andvarious kinds of
sewage in the near-
shore zone are collected in a centralized mode and discharged into a
municipal sewage system or enter an independent
water treatment device. The method is convenient to construct, low in
engineering investment, short in construction period and low in operation and maintenance cost, can effectively collect and treat pollutants entering the river, and has popularization and application prospects in the aspect of
river water environment treatment.
