Abstract: The present invention relates to a recycle water treatment system for car wash comprising principally a flocculating sedimentation tank, a flotation tank, a tank of aerobic biofilter, a secondary sedimentation tank and a storage tank that are connected in sequence, wherein a flocculent feeder is equipped at the top of the flocculating sedimentation tank; a flotation aerator is equipped at the bottom and a float scraper is equipped at the top of the flotation tank; and an aerobic filter is equipped at the middle and an aerator is equipped at the bottom of the tank of aerobic biofilter, the inlet pipe of the flocculating sedimentation tank being the inlet pipe of the system of the invention, and the outlet pipe of the storage tank being the outlet pipe of the system of the invention. Such a system is particularly applicable for small- and medium-sized car washes, because it's effective in practical operation and convenient in installation and maintenance due to compactness.

Abstract: This invention relates to a treatment system of low concentration sanitary sewage, mainly comprising a primary filtering device, a cyclone separator assembly and an aerobic biochemical treatment fluidized bed. The primary filtering device, cyclone separator assembly and aerobic biochemical fluidized are connected orderly. The primary filtering device is composed of several filtering modules, the cyclone separator assembly is composed of several cyclone separators, and the aerobic biological treatment fluidized bed is composed of several aerobic biochemical treatment modules. Such a system is suitable for small-scale and low-concentration sanitary sewage treatment, which has the advantages of good treatment effect, compact structure, flexible installation and small land used.

Abstract: This invention concerns a low concentration sewage treatment system combined with landscape, comprising a primary filter unit, a rotation flow separator combination and a primary aerobic aeration tank, wherein the back of said primary aerobic aeration tank is connected with a wetland bio-landscape facility of residential plot, the said wetland bio-landscape is equipped with aeration plants. This system adopts wetland, a kind of bio-landscape in a residential district, as a meaning of sewage purification to reduce capital investment and land occupation and to beautify the environment.

Abstract: The present invention relates to a treatment system of high concentration organic sewage treatment. The system mainly comprises a chemical settling device, an anoxic biochemical treatment fluidized bed, an anaerobic biochemical treatment fluidized bed and an aerobic biochemical treatment fluidized bed. The said primary filter device, chemical settling device, anoxic biochemical treatment fluidized bed, anaerobic biochemical treatment fluidized bed and aerobic biochemical treatment fluidized bed are connected in sequence. The said primary filter device is composed of several filter modules. The said chemical settling device is composed of several chemical settling units. The said anoxic biochemical treatment fluidized bed unit is equipped with several anoxic biochemical treatment modules.
