When the rainwater passes through the pre-abandoned flow filtering equipment, the rainwater is mainly discharged from the low-level open sewage treatment tap water according to the practical effect of acting force. After the rainfall is enlarged, the working pressure of the partition board is enlarged, the floating ball at the upper end of the discharge pipe closes the discharge pipe under the action of the working pressure of water flow, the liquid level meter in the barrel rises, and the rainwater flows into the water outlet after being filtered by the horizontal filter to be solved. After rain stops, along with the reduction of the rainwater stored by mechanical equipment, the floating ball is fully automatically calibrated under the actual effect of the spring force, and the waste generated by filtering in the barrel is brought out to finish the functions of front-stage rainwater flow discarding, filtering, full-automatic sewage treatment and the like.

The filter materials in the sand cylinder are divided into two types, one type is mainly made of traditional quartz sand, and impurities such as suspended matters, colloid, sediment and the like in water can be removed. There are disadvantages: for example, quartz sand is easy to harden, the available filtering area and performance of the surface of the quartz sand can be reduced, and the quartz sand needs to be replaced once in 2-3 years; a novel AFM active filter medium (novel glass sand) has 4 microns of filter precision, water purification effect which is 5 times that of the traditional quartz sand scheme, can not harden, can be used for more than 15 years, has lower required frequency and shorter required time on back flushing, and saves water resources
The function and action of the water disinfection device 6 are similar to that of coagulant administration devices, the types of the administered medicaments are different, the water disinfection medicaments are mainly water disinfection medicaments, and the specific medicaments are selected according to the actual conditions on site. For disinfectant dosing devices, the main current sterilization modes in the market at present are: ultraviolet sterilization, salt machine sterilization, ozone sterilization, dosing sterilization and the like, and can be configured as required. The ozone sterilizer is mainly electrified to generate ozone, can oxidize and decompose enzymes required by glucose in bacteria to inactivate the bacteria, has good sterilization effect, but the concentration is noted, and the ozone has stimulation to human respiratory tract mucous membrane and cannot exceed 0.15ppm; the ultraviolet sterilizer irradiates through the lamp tube to lead the microorganism to cause the breakage of molecular chemical bonds, has high sterilization efficiency and high speed, and simultaneously does not add chlorine in the sterilization process, and does not generate toxic gas and harmful byproducts in the sterilization process. However, ultraviolet disinfection does not have continuous disinfection capability, and is generally matched with other long-acting disinfectants for use. The salt machine is mainly used for sterilizing by electrolyzing salt to generate secondary chlorine, and the chlorine is dissolved in water to generate sodium chlorate, and the sodium chlorate sterilizing liquid is harmless to human body, so that the problem that the standard of chlorine in the past chlorine-containing sterilizing agent is exceeded and threatens health is solved, and the salt machine is a main sterilizing mode in foreign countries.
