摘要： A method for predicting operation effectiveness of a decentralized sewage treatment facility by using a support vector machine, comprising: simultaneously collecting an influent conductivity and an effluent conductivity, and recording operation effectiveness of the decentralized sewage treatment facility; training a training set by using the support vector machine, with the influent conductivity and effluent conductivity as input and the operation effectiveness of decentralized sewage treatment facilities as output, so as to construct a prediction model for the operation effectiveness of decentralized sewage treatment facilities; and collecting the influent conductivity and effluent conductivity of the treatment facilities to be predicted, and inputting them into the prediction model to obtain a predictive result. The method is not only highly accurate, but fast and inexpensive.

摘要： A biochar is produced by co-pyrolysing an aquatic plant enriched with heavy metals with a clay mineral, and the aquatic plants themselves have high enrichment and adsorb heavy metals in contaminated water; heavy metals are in situ adsorbed, and are coated or enriched in the biochar, therefore extending the migration time of heavy metals, which are also very stable; attapulgite and montmorillonite as clay minerals are loaded in the biochar during the preparing process; heavy metals contained in the biochar play a catalytic role, and synergy with activated attapulgite, therefore increasing the reliability of the biochar, and effectively reducing the ecological effectiveness and potential risk of heavy metals in the biochar.

摘要： A horizontal flow water treatment method and wetland biofilter system with improved flow control via a tubular apparatus and further comprising a chamber with impermeable outer walls spaced away from permeable interior walls of a media filtration bed such that a catch basin is formed between the outer walls and the interior walls. The catch basin creates an open area around the perimeter of the interior walls for influent water to fill within the open area on all sides before penetrating the filtration media, providing a large surface area for influent water to interact with the media filtration bed. The influent water enters the catch basin in a horizontal flow path to provide for pre-settling of particulates before making contact with the filtration media. The biofilter design increases the available surface area of the media filtration bed by up to four times for a given volume of water, and thereby minimizes the loading or infiltration rate on the media filtration bed.

摘要： A bioretention pond includes a pond body and an overflow weir. The pond body includes a pond wall and a layered substrate. The layered substrate includes from bottom to top: a gravel layer, a transition layer, a pyrite layer, a plant layer, a pebble water layer, an organic layer, and a water storage layer. The overflow weir is disposed on the pebble water layer with a space left above the center of the pebble layer. The organic layer is disposed in the space and covers the pebble layer. The water storage layer is disposed onto the organic layer. The pond body further includes a perforated pipe disposed in the gravel layer; and the perforated pipe includes an outlet end disposed at the top part of the pyrite layer.

摘要： A system (20, 70) for water treatment includes a plurality of containers (22, 24, 26, 80) which are configured to be stacked one on another for shipment and to deployed in a row at different, respective heights at a water treatment site. Each container includes an inlet (37, 86) at a first side of the container and an outlet (88) at a second side of the container, opposite the first side. The containers are filled with substrates (36, 38, 40) configured for planting of aquatic plants (60) therein and including at least different first and second substrates for filling the first and second containers, respectively. Piping includes at least an inlet pipe (34) for connection to the inlet of a first container, a transfer pipe (64, 66) for connection between the outlet of the first container and the inlet of a second container, and an outlet pipe (41) for connection to the outlet of the second container.

摘要： The invention discloses a method for harmless treatment of cyanophytes and suspended solids accumulated in lakeside wetlands, comprising the following steps: first, adding a flocculant to a water body to be treated, so as to allow the flocculation of cyanophytes to accumulate in the surface layer of the water body, and settling the formed cyanophycean floc to the surface layer of sediments; second, adding a floc stabilizer to perform accumulation and compaction of the cyanophycean floc and stabilized treatment of the floc in the surface layer; finally, conducting further reoxygenation treatment on the bottom water body. The method of the invention can realize efficient and ecologically safe flocculation of accumulated cyanophytes at low cost and control odor compounds such as sulfides decomposed from flocculated cyanophytes, so as to provide a new method for harmless treatment of excess cyanophycean accumulation in eutrophic lakes.
