Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, and particularly relates to a treatment device for inferior class V polluted surface water. Background Technique

[0002] Inferior class V surface water refers to water bodies whose pollution degree has exceeded class V. Their water quality has deteriorated severely, and the basic water use function has been lost. Class V water is mainly applicable to agricultural water areas and general landscape requirement waters, while the pollution degree of inferior class V water bodies is more serious, with poor water quality, not suitable as a drinking water source, and even less suitable for boiler water use.

[0003] Boiler water has certain water quality standards to ensure the safe and efficient operation of boilers, prevent problems such as scaling and corrosion. Due to serious pollution and containing a large amount of harmful substances, directly using inferior class V surface water as boiler water will cause scaling and corrosion inside the boiler, thus affecting the thermal efficiency and service life of the boiler, and even possibly leading to safety accidents. When using boiler water, if inferior class V water is not used, it will result in the underutilization of inferior class V water and reduce the utilization rate of water resources.

The multi-media filter 3 includes: a filter cylinder 31, anthracite material 32, and quartz stone material 33.

The liquid inlet end of the multi-media filter 3 is arranged at the top of the filter cylinder 31, and the liquid outlet end of the multi-media filter 3 is arranged at the bottom of the filter cylinder 31, so that the water in the inner cavity of the coagulation inclined tube sedimentation tank 2 can directly flow into the top of the anthracite material 32, and through the filtration of the anthracite material 32 and the quartz stone material 33, the filtered liquid flows out from the bottom of the quartz stone material 33, enabling the anthracite material 32 and the quartz stone material 33 to remove impurities such as sediment, suspended matter, colloid, and organisms such as algae in the water, and improving the filtration effect on water quality impurities;

[0029] Further, the multi-media filter 3 is connected to an activated carbon sand filter 4 through a connecting pipe. The multi-media filter 3 and the activated carbon sand filter 4 are used for the impurity removal treatment of small substances in water quality. The activated carbon sand filter 4 includes: a cylinder body 41, activated carbon particles 42, and quartz sand particles 43.
