In the technical scheme of above-mentioned sewage works, technical scheme can also be more specifically: described one-level setting device, described secondary setting device, described coagulation reaction device, described tilted plate separator, described detection groove and described pressure filter are equipped with water return pipeline, be equipped with the backwater pneumavalve on the pipeline of every described water return pipeline, described backwater pneumavalve is connected with described pneumatic controller by air pipe; Every described water return pipeline all is communicated with described former pond by underground ditch.
Further, described former pond is provided with oil trap and water reservoir.
Owing to having adopted technique scheme, compared with prior art, the beneficial effect that has is in the present invention:
1, because sewage works is to design according to lead ion sedimentation in sewage and other impurity sedimentation feature, in sewage plumbous mud and other impurity and moisture from effective, the water quality after processing meets the relevant emission standards of country and local environmental regulations.
2. the trees that are back to production and pouring lawn and on-site capable of circulation of the water after processing, saved water consumption, reduced cost.
The plumbous mud cake of 3, discharging in sewage disposal can send smeltery, saves production cost.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
Sewage works as shown in Figure 1 includes two former ponds, former pond 8 and former pond 16, and its pond, Central Plains 16 is standby as emergency lagoon; Divide equally and be separated with oil trap and water reservoir in each former pond, the liquid level meter of measuring liquid level all is equipped with in each former pond.Waste disposal plant has one-level setting device 6 and secondary setting device 5 and the coagulation reaction device 4 that is communicated with by water lines successively, and the water-in of one-level setting device 6 is communicated with the water outlet in former pond 8 and former pond 16 respectively; All by pipeline, drug metering pump 18 and balling iron 17 are housed between one-level setting device 6 and secondary setting device 5 and between secondary setting device 5 and coagulation reaction device 4, drug metering pump 18 is connected and all by air pipe, with pneumatic controller, is connected with balling iron.The water outlet of coagulation reaction device 4 is communicated with the water-in 3-1 of tilted plate separator 3; Five mud discharging mouth 3-3 are equipped with in tilted plate separator 3 bottoms, and five mud discharging mouth 3-3 are communicated with the mud inlet of plumbous mud sump 11, and the mud mouth of plumbous mud sump 11 is communicated with pressure filter 9 by power-driven pump 10; The water outlet 3-2 of tilted plate separator 3 is communicated with the water-in in middle pond 1 by detecting groove 2, the water outlet 3-2 of tilted plate separator 3 and detect between groove 2, by pipeline, drug metering pump 2-1 and balling iron 2-2 are housed, drug metering pump 2-1 and balling iron 2-2 all are connected with described pneumatic controller by air pipe.One-level setting device 6, secondary setting device 5, coagulation reaction device 4, tilted plate separator 3, detect groove 2 and pressure filter 9 water return pipeline all is housed, the backwater pneumavalve all is installed on the pipeline of every water return pipeline, the backwater pneumavalve is connected with pneumatic controller by air pipe; Every water return pipeline all is communicated with former pond 8 and former pond 16 respectively by underground ditch 13.
In work, the sewage that produces in store battery production is introduced into the oil trap in former pond 8, removes oil slick; Sewage enters water reservoir from the passage gravity flow, stop in water reservoir 8 after 6～7 days and enter one-level setting device 6 by sewage pump 7, in one-level setting device 6, by drug metering pump 18 and the balling iron 17 that is communicated with one-level setting device 6, the pH value of sewage is transferred to 4.9～5.1, and qualified sewage overflow enters the secondary setting device; Defective when the pH value of sewage, the backwater pneumavalve is opened, and sewage is got back to former pond 8 by water return pipeline through underground ditch 13.Enter drug metering pump 18 and the balling iron 17 of sewage by with secondary setting device 6, being connected of secondary setting device, the pH value of sewage is transferred to 9.9～10.1, qualified sewage overflow enters secondary setting device 5; Defective when the pH value of sewage, the backwater pneumavalve is opened, and sewage is got back in former pond 8 through underground ditch 13 by water return pipeline.Sewage self-flowing in pH value 9.9～10.1 scopes enters coagulation reaction device 4, and in coagulation reaction device 4, sewage and coagulating agent and coagulant aids are mixed in tilted plate separator 3 and react; The impurity coagulation that is difficult to sedimentation tiny in sewage is formed flocs unit; Plumbous mud enters the sludge bucket of tilted plate separator 3 under action of gravity; Power-driven pump 10 is sent into plumbous mud in pressure filter 9, and the compacting by pressure filter 9 draws plumbous mud cake and sewage; Sewage send by water return pipeline and gets back to former pond 8 through underground ditch 13, and plumbous mud cake is sent into smeltery.Enter the clear water zone of tilted plate separator 3 and from the zig-zag overflow weir, overflow to enter by the clear water after clarifying contaminated liquids and detect groove 2, detect the pH value of clear water, add a certain amount of sulfuric acid in clear water, the pH value of clear water is transferred to 6～9; Defective when the pH value of clear water, the backwater pneumavalve is opened, and clear water is got back to former pond 8 by water return pipeline through underground ditch 13.Detecting the clear water of pH value in 6～9 scopes in groove gets final product by entering middle pond 1 after filtering.Because sewage works is that the feature of water ph value designs while according to lead ion sedimentation in sewage and other impurity sedimentation, maximizing, to the good separating effect of plumbous mud in sewage and other impurity and water, the water quality after processing meets the relevant emission standards of country and local environmental regulations.
