Referring to Fig. 1 to Fig. 8, the utility model embodiment provides waste water treatment system in a kind of benzene chloride production, including First former pond 50, the second former pond 60, sedimentation basin 70, pressure filter 80, the first former pond 50 is the pond body of open top, in pond It is covered with removable top cover at the top of body, means for feeding acid 51 is set above the water inlet at the top of pond body, acidic materials are added To the first former pond 50, pH value adjusting is carried out, pipeline, one end of pipeline and first are set in the top of the first former pond 50 The outlet of former pond 50 connects, and the other end is connect with sedimentation basin 70, and aerator 52, the exposure are arranged in the first former pond 50 Device of air 52 is set to the bottom of the first former pond 50, and is located at center, and aerator 52 is round coil, in circular discs Stomata 53 is opened up on the side wall of pipe, is entered inside the first former pond 50 with the compressed air being fed in round coil, the gas The direction that opens up in hole 53 oliquely downward tilts, and the bottom of first former pond 50 is intermediate convex bottom of pond high, edge is low, also Sewage pipe 54 is set at the edge of convex bottom of pond, second former pond 60 has identical structure, precipitating with the first former pond 50 Pond 70 is open-topped pond body, the setting first partition 71, second partition 72, third partition 73 inside sedimentation basin 70, first Partition 71 is arranged close to a side wall of sedimentation basin 70, and pond body is divided into sediment space 77 and processing space, sediment space 77 volume is greater than the volume of processing space, and the second partition 72 and third partition 73 are set to inside processing space, will Processing space segmentation is independent a Room 74, two Room 75, three Room 76, and a Room 74, two Room 75, three Room 76 are successively adjacent sets It sets, the pipeline of the first former pond 50 discharge raw water is connected to a Room 74, and the bottom of a Room 74, two Room 75 and three Room 76 is taper Bottom, the conical lower portions of two Room 75 is enclosed construction, and the conical lower portion of a Room 74 opens up communication port, the conical lower portion of three Room 76 Also communication port is opened up, communicating passage 761 is set in the communication port of 74 bottom of a Room and between the communication port of three Room, 76 bottom, with One Room 74 is connected to three Room 76, first through hole 731 is opened up on the third partition 73 also between three Room 76 and two Room 75, it will Three Room 76 are connected to two Room 75, open up the second through-hole 711 on first partition also between two Room 75 and sediment space 77, with Two Room 75 are connected to sediment space 77, the height of the first through hole 731 is lower than the height of the second through-hole 711, described heavy Outlet is opened up on the side wall in shallow lake space 77, to connect with pressure filter 80, by the water being disposed filtration treatment again, filters pressing The discharge water of device 80 is connect by pipeline with the overflow launder for being set to 70 right side of sedimentation basin, to pass through overflow launder for the water after filters pressing Discharge is also arranged acid-base accommodation device in the top of sediment space 77, alkaline matter is added to sediment space 77, to adjust Water-saving is alkaline.

Sedimentation basin 70 is divided into sediment space 77 and processing space, and processing space is divided into three rooms again, and a Room 74 is used It is adjusted according to the pH value of water quality, so that water quality meets the requirement of postorder desalination process, aerator is set inside three Room 76 52, water is further aerated, and the setting of communicating passage 761, keeps the acid-base accommodation material mixing that a Room 74 is added more equal Even, a Room 74, two Room 75 and three Room 76 are connected to the channel for forming tortuous detour, so that the acid-base accommodation material mixing in water is more Uniformly, and two Room 75 are connect eventually as cushion space with sediment space 77, and the water mixing for flowing into sediment space 77 is equal Even, consistency is good.

The tubulation that round coil compares with linear, no bending dead angle, gas vent 53 are not easy to plug, and convex bottom of pond is set It sets, be conducive to the impurity in raw water or be deposited in water flow and the lower nature of weight effect to edge flowing, flow to sewage pipe 54, it is convenient Cleaning, without artificial individually that impurity is mobile to edge, aerator 52 is also disposed on center in addition, as gas is upward It emerges and raw water is driven to float upwards, the impurity in raw water has also further been pushed to deposit to from center to edge is mobile.Wherein, gas Hole 53 opens up direction oliquely downward inclined design, it may have special effect, compressed gas along opening up diagonally downward Stomata 53 is discharged, and into inside pond body, the water inside pond body to floating is seethed, and gas can also be used as the power seethed Source so that the contamination precipitation settled downwards is also blown to suspension, then settles, Er Qieqi so that raw water is seethed from bottom to top Body also blows to convex bottom of pond, so that the precipitating being deposited among bottom of pond is not blown to suspension yet, then settles to edge, into one Step, avoids the deposition in pool bottom middle position, also helps collect to edge and precipitate.

Further, setting drains pipeline below the taper of two Room, 75 bottom of sedimentation basin 70, for sediment to be discharged, puts Although valve is arranged on road, the bottom of the communicating passage 761 between a Room 74 and three Room 76 is bending bottom 762, bends bottom 762 minimum point is arranged close to three Room 76, and setting drains pipeline below the minimum point of bending bottom 762, for precipitating to be discharged Object.Bending bottom 762 can elongate the length of flow that liquid flows to three Room 76 from a Room 74, using precipitate, and with The direction of water flow, forms impact nest close to 762 minimum point of bending bottom of three Room 76 setting, forms choked flow limitation to sediment, And then be conducive to precipitating here sedimentation collect, from drain pipeline discharge.

Module or unit in the utility model embodiment device can be merged according to actual needs, divide and be deleted Subtract.

Above disclosures are merely preferred embodiments of the utility model, the utility model cannot be limited with this certainly Interest field, those skilled in the art can understand all or part of the processes for realizing the above embodiment, and according to this reality The equivalent variations made by novel claim, still falls within the scope of the utility model.
