Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
As shown, a kind of dyeing waste water pretreatment unit of the present invention, including reaction tank 1 and chemical feed pipe 2, it is described
Water inlet pipe 3 is equipped with above reaction tank 1, lower section is equipped with outlet pipe 4, and 4 head of outlet pipe is equipped with gravity turnover panel floor drain 5, water outlet
In being horizontally disposed in the middle part of pipe 4, it is parallel with the road 2-4 branch pipe 6 in the middle part of outlet pipe 4, movable strainer 7 is equipped in the branch pipe 6, it is described
2 connected reaction pond of chemical feed pipe, 1 side-lower, flocculant medicament 8 is equipped with inside chemical feed pipe 2, and 1 side of reaction tank is equipped with probe 9.
A kind of dyeing waste water pretreatment unit of the present invention, structure is simple, easy to use, and dyeing waste water is from water inlet pipe
3 enter reaction tanks 1, and the spring plate-turning of gravity turnover panel floor drain 5 is to close at this time, water slowly height, probe monitors to water
After reaching a certain height, chemical feed pipe 2 flows out flocculant medicament 8 and waste water reaction, the discharge of medicament 8 are fixed, reaction tanks
The spring plate-turning of gravity turnover panel floor drain can just open draining when interior sewage water reaches more than half, put gravity after a part of water
It reducing, gravity turnover panel floor drain is closed, and continue water storage and reacted with flocculant, is discharged water until next time, physical method of the present invention and chemistry
