How to reduce odor in rural sewage treatment

kinglv2018-07


It is common to produce odor in the process of rural wastewater treatment. In the past, due to the limited technical means and the lack of attention, the treatment of odor was neglected while treating rural waste water.  Now, with the strengthening of the concept of environmental protection, whether it is harmful gas or foul smell, it makes the public unbearable. Reducing odor elimination has become a problem that must be considered in rural wastewater treatment. As a high-end decentralized sewage treatment equipment service provider, Kinglv environmental protection pays more attention to the control of odor in various types of domestic sewage treatment projects, the following shows you how odor is produced and how to control the odor while treating rural wastewater.


How is odor produced while treating rural wastewater?


The generation of odor is directly related to the collection and treatment process of sewage. Rural sewage is mainly domestic sewage, the odor will be produced in domestic sewage and anaerobic microorganisms occupied solid. These anaerobic microorganisms consume organic matter, sulfur and nitrogen. Usually the domestic sewage contains enough organic sulfur and inorganic salts. Odor components include organic molecules and inorganic molecules, the two main inorganic gases are hydrogen sulfide and ammonia. Organic odors are usually the result of biological activity, which decomposes organic matter into a foul odor made up of various organic gases.


How to reduce odor in rural sewage treatment?

Odor gas is mainly produced in the pretreatment process. Through the pretreatment process, the odor gas in the initial structure is released into the air. Sewage contains many odor-producing substances, because most of the rural sewage treatment using biological treatment, microorganisms in the decomposition of organic matter will inevitably release odor. In order to reduce the odor produced in the biological treatment system, the organic load in the water can be controlled to reduce the volatile substance in the sewage. In addition, it can reduce the volatilization by lowering the water intake and increasing the chemical substances. During the pretreatment stage of the grill collection process, odor is generated. The organic matter adheres to the scorpion and rots continuously to produce odor. The accumulated solids need to be cleaned regularly, the grille must be cleaned and maintained according to the maintenance manual and mechanical requirements.


Most of the rural sewage treatment projects adopt underground integrated sewage treatment equipment, it is not easy to produce odor when the project is completed. However, most of the design life of rural sewage treatment project is more than 15 years, and the corrosion problems of integrative sewage treatment equipment and pipelines often have close relation with the odor. Therefore, the Kinglv environmental protection selects long life of materials.


Integrated Wastewater Treatment Equipment


The production of odor is inevitable. Reducing odor not only depends on equipment and construction, but also on the project budget expenditure, as well as equipment maintenance, space constraints, the content of harmful substances and many other factors. Therefore, rural sewage treatment requires a lot of joint efforts in the control of odor.
