Problems solved by technology

[0003] Although the traditional activated sand filter is a high-efficiency filter that integrates coagulation, clarification, and filtration, it still has the following defects: high energy consumption, high operating costs, and the need for external equipment; backwashing is difficult , the quality and efficiency are low; in the traditional adsorption, the particle filter material remains relatively static, and after long-term use, it will lead to problems such as uneven adsorption of the particle filter material and poor adsorption efficiency. Therefore, we propose a backwashable wastewater purification micro Apparatus and method for particle suspension

Abstract

The invention discloses a backwashing device for purifying micro-particle suspended matters in wastewater, and belongs to the technical field of waste water purification. The device comprises a housing, a top disc is transversely and fixedly arranged between the inner top of the housing and the inner bottom of the top cover, a chassis is transversely and fixedly arranged between the inner bottom of the housing and the inner top of the bottom cover, a plurality of groups of filtering pipes are arranged on the inner sides and the outer sides of the top disc and the bottom disc in an annular array manner, a backwashing mechanism is arranged at the bottom of an inner cavity of a bottom cover, and a collecting mechanism is arranged at the bottom in the top cover. The use cost is low, in wastewater purification, the position of the particle filter material inside is moved and adsorption efficiency and quality of the granular filter material are improved, and in the backwashing process, the contact area of the particle filter material and the water flow sprayed by the inner wall of a filter pipe and a nozzle can be increased, the wastewater purification efficiency and purification qualityand the flushing efficiency and flushing quality of the particle filter material and the inner wall of the filter pipe can be improved, and the space of the device can be utilized to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of wastewater purification, in particular to a backwashable device and method for purifying suspended matter in wastewater microparticles. Background technique [0002] The working principle of the traditional activated sand filter is that the raw water enters the inside of the filter through the water inlet pipe, and after being evenly distributed by the water distributor, it flows upward to the filter material layer and discharges outward. It is mainly used to remove suspended particles of micro particles in the wastewater. It is mostly used in the treatment of industrial sewage, the pretreatment of seawater desalination, etc. During the treatment process, the raw water is filtered, and the pollutant content in the water decreases, while the pollutant content in the quartz sand filter material increases, and the pollutant content in the lower filter material layer increases, and the pollutant content in th...
