Description of drawings:
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the sectional structure chart of the said water-and-oil separator of the utility model.
Fig. 2 is the plan structure figure of the said water-and-oil separator of the utility model.
Embodiment:
For technique means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As depicted in figs. 1 and 2, the described water-and-oil separator of the utility model, this device main body comprises a separation cell 1, is provided with the water inlet pipe 2 that is used for injecting oily(waste)water at the separation cell head end; In separation cell, be provided with foreign material discrete blocks 3 near 2 mouthfuls of the water inlet pipes, this is stated foreign material discrete blocks 3 and is used for the large granular impurity in the separating and filtering oily(waste)water; In separation cell, be mounted with cavitation air flotation aerator 4, this is stated cavitation air flotation aerator 4 and is attached on through a large amount of micro bubbles that in oily(waste)water, produce and oil droplet is floated to liquid level around the olesome rapidly.
