First of all, restaurant owners and employees don't pay enough attention to the sewer, which leads to many items that should not enter the sewer being thrown in. For example: food residues, grease, coffee grounds, cigarette butts, wet wipes, paper and so on. These items will pile up in the sewer, and once they meet a bend, they will form a blockage.
Secondly, garbage such as silt and leaves may enter the pipeline during the rainy season, and these substances will also accumulate in the sewer to form a blockage.
In addition, the problem of pipeline disrepair and damage is also an important reason for sewer blockage. With the aging of the pipeline, the inside of the pipeline becomes more and more rough due to long-term corrosion, which leads to the phenomenon of dust accumulation in the pipeline, which is easy to become a foreign body to stay and slowly collect components.
In addition, excessive bending or improper direction of sewers may also lead to blockage. Too many elbows in the pipeline will hinder the construction of water flow conditions, increase the upstream water inlet pressure and reduce the downstream water inlet easily, which is an important factor leading to blockage.
Restaurant managers and employees should establish a correct mechanism for the treatment of kitchen waste food and grease. Such as harmful waste sorting, cleaning customer tableware, packaging bags, paper scraps, etc. before table cleaning. At the same time, strengthen pipeline inspection, regular cleaning and maintenance, find pipeline aging and damage problems as soon as possible, and repair them in time to avoid dirty oil pollution and odor.
