Specific embodiment
Technical scheme is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
As illustrated in fig. 1 and 2, present invention offer is a kind of cuts dirty and biological floating bed integral system, including section dirty system 1 and a life
State floating bed system 2, cuts dirty system 1 and is located at sewage draining exit, and biological floating bed system 2 is located at the downstream for cutting dirty system 1, leads between the two
Cross aeration tube to be connected.
Referring to Fig. 1, cutting dirty system 1 includes cutting dirty plate 11, the aerator 12 being arranged on above section dirty plate 11 and being arranged on cutting
The aeration tube 14 of 11 lower end of dirty plate, wherein, several section of dirty plate 11 is sequentially connected, and each cut dirty plate 11 can be along being adjacent
The connecting shaft for cutting dirty plate 11 is turned folding, and to be cut and be provided with water-level gauge on dirty plate 11, and water-level gauge can voluntarily identify water level, and according to inspection
Controlling to cut expansion and the folded state of dirty plate 11, when rainy season, water level was too high, cut a dirty plate 11 voluntarily can fold the water level for measuring
Excretion flood, so arranges and section dirty plate 11 can be protected without damage, improve the service life for cutting dirty plate 11.Each is cut on dirty plate 11
Side is provided with a solar panels 13, and several solar panels 13 are in shift to install up and down, it is to avoid be folded over a dirty plate 11 is cut
Mutual collision in journey between each solar panels 13, is generated electricity by solar panels 13, can be made to be arranged on and be cut above dirty plate 11
Aerator 12 is simultaneously for cutting 2 aeration of dirty system 1 and biological floating bed system.In addition, after cutting the dirty folding of plate 11, using aerator 12
Backwash is carried out, and prevents section dirty plate 11 from plug is gambled because of permanent use.
Each cuts dirty plate 11 includes filter layer and biological membranous layer, and filter layer is gabion filtrate, and gabion filtrate is using tiny
Stone is constituted, and in sewage, larger organic particulate matter is retained by filter layer, while the filter layer that gabion filtrate is constituted has greatly
Specific surface area, it is possible to provide microorganism adheres to form biological membranous layer, the bulky grain Organic substance in preliminary purification water body, biological membranous layer
On microorganism can accelerate the decomposition of Organic substance, be that subsequent treatment is reduced and processes load, preliminary purification water quality, little for resolving into
Grain material flows into follow-up biological floating bed system 2 and is further purified.
Referring to Fig. 2, biological floating bed system 2 is layer stereo structure, builds the more biological of many integration using micro-pore aeration
Cleaning system, wherein, orlop is aeration tube stratum reticulare 21, and aeration tube stratum reticulare 21 is connected with the aeration tube 14 for cutting dirty system；Aeration
Artificial aquatic weed layer 22 is laid above pipe network layer 21, artificial aquatic weed has great specific surface area, improves the attachment of microorganism, energy
Further Organic substance is decomposed；Above artificial aquatic weed layer 22 be submerged plant layer 23, submerged plant layer 23 can plant Herba vallisneriae Spiralis,
And/or black algae, according to《Herba vallisneriae Spiralis and black algae are analyzed to the removal for simulating CODMn and TN and NO3-N in West Lake Water Body》(Li Ze, height are little
Brightness, He Feng etc. write) to record, Herba vallisneriae Spiralis and black algae have good effect to water body purification；The superiors are floating plant layer 24, can be planted
Plant the plants such as Herba Typhae, phragmites communiss, cyperus malaccensis or Bermuda grass.It is submerged plant layer 23 in the middle of ensureing not because upper strata floating plant layer 24 hides
