The utility model is the treating plant that is specifically applied to Chemistry Laboratory in Middle School, simple in structure, cost is low, the organic and inorganic waste collection that is produced in the middle school chemical experiment can be got up and carry out purifying treatment, remove the material that in the waste liquid environment is polluted, waste liquid after the purification can reach state sewage emission standard, has solved not treated and the problem that discharging pollutes environment of existing chemical experiment waste liquid.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of solid-liquid separating machine among the utility model embodiment.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: be provided with the waste liquid tank made from corrosion resistant material 1, visual window (or make waste liquid tank with transparent material) need be installed, on waste liquid tank 1 so that see organic phase and inorganic situation mutually in the chemical waste fluid clearly.Waste liquid tank 1 joins with neutralization reaction groove 4, separating organic matters device 5 respectively by regulated valve 2, by-pass valve control 3, acidometer should be set so that waste liquid is transferred to neutrality in the neutralization reaction groove 4.The inlet of the lower end of neutralization reaction groove 4 and recycle pump 7 joins, the upper end joins by the circulation valve 6 and the outlet of recycle pump 7, the outlet of recycle pump 7 is also joined with solid-liquid separating machine 9 by separating valve 8, the filtrate receiver 10 that joins with solid-liquid separating machine 9 joins by the inlet of Clean water valve 11 with recycle pump 7, and separating organic matters device 5 joins by by-pass valve control 12 and filtrate receiver 10.For filtrate is further purified, the outlet of recycle pump 7 is joined with cleaner 14 by purifying valve 13, also can be serially connected with cleaner 15,16 with cleaner 14.
Solid-liquid separating machine 9 can be centrifugal or the extruding type solid-liquid separating machine, but for structure simpler, available vacuum separation machine as shown in Figure 2, housing 17 is promptly arranged, in housing 17, be horizontally arranged with screen plate 18, screen plate 18 will be separated into solid-liquid separation tank 19, filtrate receiver 10 up and down in the housing 17, be connected to filtrate with filtrate receiver 10 and portal 20 and valve tube 21, and valve tube 21 joins with vacuum pump 22.Vacuum pump 22 can be general vacuum pump or water ring vacuum pump, if use water ring vacuum pump, water ring vacuum pump 22 can be placed in the interlayer 23 below the filtrate receiver 10, and be water ring vacuum pump usefulness tank 24 below the interlayer 23, reverse checkvalve 25 is connected in valve tube 21 pipelines.
