Energy-saving and environment-friendly sewage treatment device having function of adjusting mixing range

Abstract

An energy-saving and environment-friendly sewage treatment device having the function of adjusting a mixing range comprises a pond body, wherein two mounting bases are symmetrically and fixedly connected to the outer side wall of the pond body, vertical reciprocating motion devices are fixedly connected to the mounting bases, each vertical reciprocating motion device comprises a supporting sleeve, the bottom ends of the supporting sleeves are fixedly connected with the mounting bases, cams are arranged in the supporting sleeves, first rotary shafts are fixedly connected to the middle positions of the cams, two ends of each first rotary shaft are erected on the side wall of the corresponding supporting sleeve, and the outer end of the first rotary shafts are fixedly connected with output shafts of first motors. Lifting rods are arranged on the cams in a contact mode, the top ends of the lifting rods are fixedly connected with supporting plates. Second motors are fixedly connected to the middle positions of the supporting plates, and second rotary shafts are fixedly connected to output shafts of the second motors. The energy-saving and environment-friendly sewage treatment device changes a flocculation range to achieve a sewage flocculation effect in a centrifugal mode, meets the sewage treatment demand and has a certain popularization and application value.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an energy-saving and environment-friendly sewage treatment equipment with an adjustable mixing range. Background technique [0002] In recent years, the discharge of industrial wastewater and domestic sewage in my country has been increasing year by year. Untreated or improperly treated wastewater is directly discharged into nature, seriously affecting environmental sanitation and threatening people's drinking water safety. Therefore, the treatment of sewage is imminent. [0003] In the process of sewage treatment, flocculation operation is often required. Flocculation makes the suspended particles in water or liquid gather larger, or form flocs, so as to accelerate the coagulation and sedimentation of particles and achieve the purpose of solid-liquid separation. This phenomenon or operation is called flocculation. Usually, flocculation is implemented by adding an appr...

Problems solved by technology

[0004] However, because it is difficult to fully mix the chemical and sewage, the reaction is insufficient, and the role of the chemical cannot be fully exerted, resulting in the sewage treatment effect not being able to achieve the expected indicators, and also causing waste of the chemical, which increases the cost of sewage treatment; in addition, sewage The ratio with the medicine is often inaccurate
