Embodiment Construction

[0021] Such as figure 1 As shown, the present invention is a small town sewage treatment process. The treatment unit of the small town sewage treatment process is composed of a water inlet well, an enhanced flocculation sedimentation device, a fluidized bed biological oxidation device and a secondary sedimentation tank. Its characteristics The whole system is a continuous flow during treatment, and the whole process is divided into four steps: water inflow, enhanced flocculation sedimentation, fluidized bed biological oxidation and post-sedimentation:

[0022] 1. Intake of water

[0023] The influent water of the present invention can be domestic sewage in small towns, mixed industrial and domestic sewage, sewage in large residential quarters, sewage in suburban junctions, and the like. Before the sewage enters the treatment device through the drainage pipe, it passes through the grid to intercept large floating objects, plastic bags, animal and plant residues, etc., and then...

Description

Technical field: [0001] The invention relates to a water treatment process, in particular to a small town sewage treatment process. Background technique: [0002] In recent years, my country has accelerated the pace of building a well-off society in an all-round way, and the urban population has grown rapidly. Many central towns or small market towns have emerged. Water pollution and eutrophication around towns have become increasingly prominent. [0003] At present, the sewage of small towns in my country is basically in a state of letting go. Small towns in many areas are located in water source protection areas or reservoirs and lakes. Untreated sewage is discharged arbitrarily, which not only pollutes large areas of water, but also reduces the use value of water. , and after nitrogen and phosphorus enter the water body, a large number of algae will grow, which directly affects the safety of drinking water in cities or surrounding towns. Small towns and the suburban junct...
