The upper part of the sedimentation tank 3 is provided with a floater filtering device 7 fixed with a baffle plate 5, the floater filtering device 7 comprises a water tank 16 with a U-shaped section, a water leakage plate 17 which can be taken out is arranged in the water tank 16, the water leakage plate 17 is a screen plate, and two ends of the water leakage plate 17 are downwards sunken to form a cavity 18 for floaters. After accumulating more impurity on the water leakage plate 17, can be to the impurity on the water leakage plate 17 manual cleaning earlier in holding chamber 18, clear out impurity from holding chamber 18 again, impurity clearance is more convenient, and it is comparatively convenient to maintain promptly.
The water leakage plate 17 is erected in the water tank 16, and can be taken out for cleaning when the water leakage plate 17 is blocked, so that the maintenance is convenient.
The bottom of the water tank 16 is provided with a water guide pipe 19. The height of the water guide pipe 19 from the bottom of the sedimentation tank 3 is one half to one third of the height of the water discharge pipe 10 from the bottom of the sedimentation tank 3, for example, when the water discharge pipe 10 is three meters high from the bottom of the sedimentation tank 3, the water guide pipe 19 is one to one point and five meters from the bottom of the sedimentation tank 3. The height setting of drain pipe 10 is that the water that makes mixing stirring pond 2 gets into from the well lower part of sedimentation tank 3 interior water, avoids directly discharging between drain pipe 10, leaves sufficient settling time, realizes higher solid-liquid separation, simultaneously, avoids rivers to strike the mud layer of sedimentation tank 3 bottom, avoids the mud layer to lift up.
The outside of cell body 1 is equipped with medical kit 20, and medical kit 20 passes through electric type and goes out medicine valve 21 and connect inlet tube 6, goes out the junction of medicine valve 21 and medical kit 20 and is located the bottom of medical kit 20, goes out the junction of medicine valve 21 and inlet tube 6 and is located between water pump 14 and cell body 1. The medicine tank 20 may be fixed to the outside of the tank body 1, and the height of the medicine tank 20 needs to exceed the water inlet pipe 6. The medicine box 20 is filled with a medicine liquid which is commonly used in the field of hard water softening, such as sodium carbonate solution, and the sodium carbonate reacts with calcium magnesium plasma to generate substances which are not easily dissolved in water, and a flocculating agent such as PAC or PAM can be added into the medicine liquid.

The water hardness sensor 22 detects the hardness of sewage, when the hardness reaches a certain degree, a signal is output to the controller 23, and the controller 23 opens the medicine outlet valve 21 to discharge the medicine liquid in the medicine box 20 and enter the mixing and stirring tank 2 through the water inlet pipe 6. The liquid medicine reacts with ions in the sewage and flocculates, so that the water quality of the sewage is softened, the signal on the water quality hardness sensor 22 disappears, the controller 23 closes the medicine outlet valve 21, and the medicine box 20 stops discharging medicine. The medicine outlet valve 21 is repeatedly opened and closed, so that the hardness of sewage in the mixing and stirring tank is moderately maintained at a certain level, meanwhile, the medicine liquid is not excessively used, and the use cost is reduced.

Compared with embodiment 1, embodiment 2 has simpler structure, does not need staff to operate the controller, and has lower staff quality requirements. The disadvantage is that the content of the easy scaling ions such as calcium and magnesium contained in the sewage input through the water inlet pipe 6 in different periods is different, and the output speed requirement of the liquid medicine is different, but the embodiment 2 is difficult to realize the matching of the output speed of the liquid medicine and the content of the easy scaling ions in the sewage, and the waste caused by the excessive use of the liquid medicine or the insufficient softening degree of the sewage caused by the insufficient use of the liquid medicine is easily caused by depending on the experience matching of workers.
Example 3. Unlike example 1, the anaerobic system has no controller 23, medicine tank 20 and medicine outlet valve 21 in the scale removing structure. The chemical solution is periodically added to the mixing tank 2 manually.
Example 4. On the basis of embodiment 1, a pool is arranged below the water outlet end of the water drain pipe 10, the pool is connected to the anaerobic system through a pipeline and a pump, and after sewage from the water drain pipe 10 enters another pool, interferon or a scale inhibitor is added at regular time, so that the sewage entering the anaerobic system is further difficult to scale.
