Technical field
The utility model relates to technical field of sewage, specifically a kind of sewage treatment eddy flow mixes medicine system.
Background technique
Currently, the sewage in sewage collecting tank enters under the action of sewage pump in the treatment process of sewage treatment facility
Sewage conveying tube, then adding sodium hydroxide for the pH value adjustment of sewage by the first chemical feed pipe is 6-7, and passes through the second dosing
Pipe adds aluminium polychloride and polyacrylamide for the solid content flocculation sedimentation in sewage, which is collected to dirt
Behind water sedimentation pond (Fig. 1), sludge is periodically pressed by mud cake by plate type pressure filter, to achieve the purpose that purification of water quality.At present
It is first to dissolve medicament in medicine-adding bin, is then added and is adjusted in pump to the pipeline between sedimentation basin by dosing pump, and medicament
Be added pipeline after because with sewage can not uniform hybrid reaction, cause flocculation sedimentation effect poor, and cause medicament largely unrestrained
Take, the consequences such as sewage effluent quality difference.
Utility model content
The purpose of this utility model is to overcome the defects of existing sewage treatment medicine system, provide a kind of sewage treatment
Medicine system is mixed with eddy flow, mixes medicament in-line uniformly with sewage, to reduce reagent cost, realizes sewage
The qualified discharge of water quality.
The purpose of this utility model is achieved through the following technical solutions: a kind of sewage treatment eddy flow mixing dosing system
It unites, including sewage conveying tube, is successively arranged the first chemical feed pipe and the second chemical feed pipe on sewage conveying tube；Wherein, the first chemical feed pipe
With second chemical feed pipe one end with sewage conveying tube is at an acute angle is connected to, sewage conveying tube one end connects sewage pump, sewage pump and sewage
Collecting tank is connected, and the sewage conveying tube other end is connected with sedimentation basin；Sewage transport between second chemical feed pipe and sedimentation basin
Pipe is equipped with rotational flow mixing device, which includes the mixing tube that caliber is greater than sewage conveying tube caliber, mixing tube
Inner wall is equipped with deflector.
As the preferred of technical solutions of the utility model, above-mentioned first chemical feed pipe and the second chemical feed pipe and sewage conveying tube it
Between be in 45 ° of angles.
The caliber of above-mentioned mixing tube is 1.25 times of sewage conveying tube caliber.
Above-mentioned deflector and the angle of mixing tube cross section are 30 °.
Above-mentioned rotational flow mixing device and the second chemical feed pipe are at a distance of 100m.
Compared with existing sewage treatment medicine system, the beneficial effects of the utility model are:
1, the utility model increases rotational flow mixing device on the sewage conveying tube after the second chemical feed pipe, dirty by changing
The flow regime of water makes medicament and sewage be sufficiently mixed reaction, to improve the flocculation sedimentation effect of solid content in sewage, reduces
Reagent cost realizes the qualified discharge of sewage quality.
2, be arranged it is at an acute angle between two chemical feed pipes and sewage conveying tube be connected to, medicament flow velocity can be reduced, increase medicament with
The incorporation time of sewage, and preferably 45° angle is connected to, and can make medicament and dirt under the premise of ensuring not influence medicament flow
Water is sufficiently mixed.
3, the caliber that mixing tube is arranged is 1.25 times of sewage conveying tube caliber, is ensuring the constant situation of the discharge of sewage
Under, its flow velocity can be reduced, residence time of the medicament in mixing tube is extended.
4, setting deflector and the angle of mixing tube cross section are 30 °, can increase mixing tube inner hollow area, are reduced
Drainage flow resistance.
5, due in rotational flow mixing device dosing will lead to the unstable (rotation of the dosing pump discharge pressure that connect with chemical feed pipe
Water flow rotary in mixing arrangement is flowed, negative pressuren zone is had), lead to dosing tube vibration；In addition, the dosing in mixing arrangement, can generate
Cavitation corrodes mixing arrangement, therefore, at a certain distance from rotational flow mixing device is set to after the second chemical feed pipe by the utility model,
At preferably 100m.
