Embodiment 1
[0015] Embodiment 1 of the present invention: the device that adds coagulant in sewage, inserts medicine spray pipeline (2) in the sewage pipeline (1) that will carry out coagulation treatment, in order to spray medicine effect more evenly, spray medicine pipeline (2) ) is sealed at the bottom, and the spray ports (4) are evenly distributed on the side of the spray pipe (2). According to the diameter of the sewage pipe (1), 2 to 8 spray holes are made port (4), connect two additional pipelines (3) for adding composite elements above the spraying pipeline (2). The coagulant can choose iron salt or aluminum salt, and the compound elements use commonly used substances such as active silicic acid and rare earth.
[0016] After testing, the distance between the connection port of the additional pipeline (3) and the spraying pipeline (2) and the spraying port (4) can be set between 5 and 50 centimeters, so that the mixing time of the medicament will not be too long and affect the E...
Embodiment 2
[0018] Embodiment 2 of the present invention: a device for adding a coagulant to the sewage, inserting the spraying pipeline (2) in the sewage pipeline (1) to be coagulated, in order to make the spraying effect more uniform, the spraying pipeline (2) ), and the spray ports (4) are evenly distributed on the side of the spray pipe (2), and according to the diameter of the sewage pipe (1), 3 to 7 spray holes are made on the side of the spray pipe (2). port (4), connect an additional pipeline (3) for adding composite elements above the spraying pipeline (2). The coagulant can choose iron salt or aluminum salt, and the composite elements use active silicic acid and rare earth.
[0019] The distance between the connection port of the additional pipeline (3) and the spraying pipeline (2) and the spraying port (4) can be set between 10 to 40 centimeters, so that the mixing time of the medicament can be controlled within 2 to 6 seconds, so that The medicament can be mixed evenly and m...
