Biological suspended packing for biochemical treatment of sewage

Introduction

Spherical suspended packing, also known as porous rotating spherical suspended packing, is a new type of packing widely used in domestic wastewater treatment biofilm method, which belongs to the most new series of products developed among many fillers. In the biochemical treatment of sewage with a full three-dimensional structure, large specific surface area, directly placed, without fixing, easy to hang film, not blocked and other advantages.

Features

Thepacking series is made of polypropylene injection molding, divided into two layers of spheres, the outside is a hollow fish network sphere, the inside is a rotating sphere. It mainly plays the role of biofilm carrier, and simultaneously intercepts suspended solids. The product has the characteristics of fast microbial hanging film, strong biological adhesion, large specific surface area, high porosity, good chemical and biological stability, durable (service life of 15 years), insoluble harmful substances, do not cause secondary pollution, anti-ultraviolet, anti-aging, strong hydrophilicity and so on. In the process of use, microorganisms are easy to grow, easy to replace, acid and alkali resistance, anti-aging, not affected by water flow, long service life, less residual sludge, easy to install.

Application

Widely used in domestic sewage, petrochemical, light industry paper, food industry, brewing, sugar, textile, printing and dyeing, leather, pharmaceutical and other industrial wastewater treatment.
