Background

Phosphorus is an important non-metallic mineral resource, is one of the most important elements for life activities, and is a non-renewable limited resource. However, as agricultural production increases, the demand for phosphorus also increases year by year. Therefore, recycling the used phosphorus is one of the methods to solve the crisis of phosphorus resources.

In the urban sewage treatment process, a large amount of sludge rich in phosphorus is generated in the sewage biological treatment process. The phosphorus is released from the municipal sludge by an effective method and is recovered in a certain form, so that the condition of phosphorus resource scarcity can be properly relieved, and the reduction of the sludge is facilitated.

At present, most of phosphorus extraction technologies are sludge acid-base treatment, heating and ultrasonic treatment to hydrolyze the sludge or ozone oxidation of the sludge, so that phosphorus in the sludge is released into water, and then the phosphorus in clear liquid is recovered through precipitation, adsorption and crystallization; the key to oxidizing the sludge by ozone is whether the sludge can be sufficiently oxidized, however, no suitable equipment exists at present.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

Examples

As shown in fig. 1-2, the utility model provides a pipeline aeration device for removing phosphorus from organic sludge, which comprises an ozone generator 1, wherein the ozone generator 1 is connected to an air inlet of an air transmission pump 2 through a pipeline, and an air outlet of the air transmission pump 2 is connected to an air distribution chamber 6 through an air transmission pipe 3; the air distribution chamber 6 is arranged at the bottom of the left end of the aeration pipe 5, and a microporous aeration plate 7 is arranged between the air distribution chamber 6 and the aeration pipe 5; the left end of the aeration pipe 5 is provided with a feed inlet 11, and the right end of the aeration pipe 5 is provided with a discharge outlet 12

In order to prevent the ozone from flowing back, a one-way valve 4 is arranged in the gas transmission pipe 3.

For improving the oxidation effect of ozone to mud, the ozone of being convenient for simultaneously can in time discharge the gas that produces in carrying out the oxidation treatment process to mud, is equipped with collection chamber 8 at the middle part upside of aeration pipe 5, the top of collection chamber 8 is equipped with disappointing valve 9, and this department's disappointing valve 9 is the ball valve.

It is noted that in order to allow the ozone to sufficiently oxidize the sludge, a gas baffle 13 is provided in the aeration pipe 5 adjacent to the right side of the gas collection chamber 8. It should be noted that the lowest position of the discharge port 12 is not lower than the lowest position of the gas barrier 13, so as to fully exert the function of the gas barrier 13.
