VOCs pollution control has always been a shortcoming and difficulty in air pollution control. It can be called a "tumor" and difficult to "cut". Only by studying the VOCs emission characteristics in different industries and understanding the pollution sources of enterprises can we formulate practical and feasible governance measures.
At present, many companies generally fall into four governance misunderstandings due to various factors:
1. Only care about initial investment, not daily operation and maintenance;
2. Only care about whether there is or not, not processing efficiency;
3. Only consider workshop ventilation, not waste gas collection;
4. Only care about equipment procurement, not overall design.
Among them, especially the VOCs governance project design lacks the concept of overall design and overall consideration. In the early stage, the temperature, flow and pressure changes of the site working conditions of different VOCs exhaust gases are insufficient, and the regularity of technical processes are lacking in the VOCs governance project design and incomplete system construction. After completion, the operation cannot meet the expected design goals, which affects the implementation effect of the governance project.
The original pollution control facilities generally have prominent problems such as "inadequate technical selection, insufficient design capabilities, unsecured safety performance, and lack of operation and maintenance", which ultimately leads to the vast majority of pollutant discharge enterprises falling into difficulties such as inability to meet the standards in a stable manner or posing safety hazards and duplicate construction, and are even unable to fulfill the main responsibility of the enterprise's environmental protection.
In this regard, FOSY Biological's technical experts said that VOCs governance is a systematic project that takes into account all aspects. Different industries have different technical routes. Even in the same industry and different processes, the technical routes will be different. Even due to different air volume and concentration, the required technical routes are also different.
In addition, there is no technology that can solve all VOCs problems. For example, as a key VOCs emission industry, every printing company has unique processes and needs, and the VOCs emitted will be different. VOCs management companies should formulate the most appropriate technical routes for different companies to prescribe the right medicine.
At present, there are dozens of VOCs treatment methods, and its principles are nothing more than two major categories: recycling technology for recycling valuable solvents and destruction technology for decomposing VOCs molecules, namely two technologies: recycling and destruction. As a manufacturer of biological enzyme VOCs treatment products, Forsy Biotech believes that even products such as complex biological enzymes that have a strong decomposition effect on multiple VOCs components cannot achieve 100% elimination of VOCs and their impact. Therefore, when choosing such products, enterprises should maintain a rational and calm mind and maintain a scientific attitude of controlling VOCs.
