Abstract

The invention belongs to the technical field of sewage treatment and particularly relates to a sewage treatment method. The method comprises the following steps of 1, sedimentation, wherein sewage ispoured into a sedimentation pond and subjected to standing for 5-8 hours, and clear water is separated from sediment; 2, coagulation, wherein clear water is poured into a coagulation pond, and a coagulant is added for coagulation; 3, filtration, wherein the water which is treated in the second step is poured into a filter pond and filtered through a rough filter layer, a fine filter layer and a refilter layer in the filter pond in sequence; 4, disinfection, wherein a disinfection pond is prepared. The disinfection pond comprises a supporting rack, a water purification barrel, an air blowing mechanism and a power mechanism; the water purification barrel is aslant and rotatably arranged on the supporting rack, and multiple water hoppers are arranged in the water purification barrel; the airblowing mechanism comprises air blowing pipes and water wheels, and the water wheels are fixed on the air blowing pipes; when the water purification barrel forward rotates, the water wheels reverselyrotate under the power effect of water which flows out of the water hoppers. According to the scheme, the contact area of chlorine and water can be increased, chlorine and water are sufficiently mixed, and the disinfection effect is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment method. Background technique [0002] As we all know, natural precipitation and lake and river water cannot be used for direct drinking or production. Due to various natural and human factors, these waters will contain various impurities, and direct drinking will cause great harm to human health. harm, so countries have thought of treating and disinfecting water. [0003] From the perspective of water supply treatment, impurities in water can be divided into three categories: suspended solids, colloids, and dissolved solids. The purpose of water purification treatment in urban water plants is to remove suspended matter, colloidal matter, bacteria and other harmful components in the raw water that will harm human health and industrial production, so that the purified water can meet the needs of domestic drinking and industrial production. ...
