Description

Method of removing scales from piping or mechanical parts{Method and Compositions for Minimizing Biological and Scale}

The present invention relates to a microbial agent for purification and removal of scales such as foreign substances or struvite generated in piping or mechanical parts of a workplace to which various biological processes are applied, and more specifically, utilizing seed germs obtained from natural plants The fermentation broth of strong lactic acid bacteria with strong activity (referred to as Baru-composite microorganisms in this application) is obtained and utilizes it to generate piping, machinery parts, and water pipes used in biological sewage treatment processes. It relates to a technique using a microbial agent to remove scale or foreign matter.

In the biological sewage treatment process, after aeration of the sewage in an aeration tank, the aerated sewage is allowed to settle the activated sludge while staying for a suitable time in the final sedimentation basin to discharge the treated water back into the stream.

The precipitated activated sludge is sent to a digester and subjected to an anaerobic digestion process, and then the digested sludge is sent to a dewatering device, leading to a dehydration process, which occurs after dehydration using a dehydration device such as a centrifuge or a press press dehydrator. Reduce the weight and volume of the sludge cake.

At this time, high concentrations of phosphate ions, magnesium ions and ammonium ions contained in the digested sludge are produced by the reaction of strumite, a hydrous ammonium salt mineral of magnesium, with the ammonia solution of phosphate and the solution of magnesia, and also guano Absences are found in sediments or in deteriorated products by bacteria of various organic compounds. Struvites, stones, and scales are attached to sludge transport piping and dewatering equipment, which are factors that reduce sewage treatment efficiency.

In the biological sewage treatment process, since the ratio of surface area and volume is greatly affected, struvite, stones, and scales are generated in the primary treatment process or in the sludge pipe or the dewatering separator pipe rather than the digester. It is easy. Especially, in the separation pipe of centrifugal dehydrator, it is decarburized rapidly, so it is easy to generate stones due to the increase in pH. Such scale or obstacles caused by stones occur throughout the dehydration process, especially when the pipe becomes narrower. It is intensively generated in the rear ends of parts and valves.

In the prior art, as a method of removing the strobite or scale generated by crystals formed in the dehydrator, the sulfuric acid addition method of strong sulfuric acid has been applied, so the dehydrator must be stopped and diluted in the dehydration reservoir. In the case of adding sulfuric acid, there has been a problem in that it is not easy to handle the chemical itself, which exhibits strong acidity, and that the dehydrator is easily deteriorated.

In addition, in the prior art, a technique for suppressing the generation of strobite or scale generated in the sludge transfer pipe by adding a scale generation inhibitor is described in Korean Patent Publication No. 10-0573186, which provides a scale generation inhibitor for scale generated in the process of chemical wastewater treatment. A method for preventing the generation of scale using a method has been proposed.
