Problems solved by technology

However, in the process of sewage treatment, it is often necessary to add powdered treatment chemicals, and the sewage and chemicals can be fully contacted and fused to play a role. Due to the continuous injection and discharge of sewage during the process of adding chemicals, some sewage and chemicals are discharged before they have time to react, resulting in sewage treatment. The effect cannot reach the expected target, and it causes waste of chemicals, and also increases the cost of sewage treatment

Embodiment 1

[0022] Such as Figure 1-2 As shown, a sewage treatment dosing agitator includes a water supply pump 1 and a dosing box 2. The outlet of the water supply pump 1 is provided with a reaction cylinder 3 communicating with the dosing box 2. The sewage enters the reaction tank through the water supply pump 1. In the cylinder 3, the medicine dosing box 2 contains medicine, and the medicine and sewage react in the reaction cylinder 3 to remove suspended solids, heavy metals and sulfides in the sewage.

[0023] The reaction cylinder 3 is set as a back-type pipeline to prolong the reaction time of the medicine and the sewage. A group of parallel sides of the back-type pipeline are respectively provided with a flow divider 4 and a water outlet 5, and the sewage and the medicine first pass through the shunt. The device 4 divides the flow into two streams, and the two streams circulate in the return pipeline respectively, and finally the two streams converge and flow out at the water outl...

Embodiment 2

[0028] Such as Figure 2-3 As shown, the same parts of this embodiment and Embodiment 1 will not be repeated, and the difference is:

[0029] A single agitator 6 is respectively arranged inside another group of parallel sides of the return-type pipeline, and after the fine stream is mixed once, it flows to the closed end 62 through the open end 61 of the single agitator 6, and the closed end 62 is close to In the bent section of the return-type pipeline, the thin stream flowing out of the water outlet hole 63 is sprayed onto the inner wall of the return-type pipeline again to realize the mixing of sewage and medicine. Finally, the two streams and the water outlet 5 are convectively sprayed. Re-mixing of sewage and medicine is realized, and by increasing the number of agitators 6, multiple mixing of sewage and medicine is realized, the uniformity of mixing is improved, and the cost of medicine is saved.

[0030] In some other embodiments, the reaction cylinders 3 are arranged ...

Abstract

The invention relates to a sewage treatment dosing mixer, which belongs to the technical field of sewage treatment equipment and includes a water supply pump and a medicine dosing box. To carry out the reaction, the reaction cylinder is set at least one stage, the reaction cylinder is set as a return-type pipeline, and a group of parallel sides of the return-type pipeline are respectively provided with a flow divider and a water outlet, and the return-type pipe Paired agitators are installed at the diverter and water outlet inside the road. The invention has the characteristics of improving the mixing uniformity of sewage and medicine, saving medicine cost, compact structure, less space occupation and high economic benefit.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a sewage treatment dosing mixer. Background technique [0002] According to the "2015-2020 China Sewage Treatment Industry Market Prospect and Investment Strategic Planning Analysis Report Prospect", 70% of China's 1.3 billion population drink groundwater, and more than 400 of the more than 660 cities use groundwater as their drinking water source . At the same time, the report pointed out that 90% of the urban groundwater in the country has been polluted. Therefore, the purification treatment of polluted effluent water from domestic and production has attracted great attention from various fields. [0003] In recent years, the industrial capacity of the sewage treatment industry has undergone qualitative changes. This qualitative change mainly involves two aspects. One is the rapid increase in the number of sewage treatment plants, and the other ...
