Everyone knows sewage treatment equipment, but few people know how sewage treatment equipment is managed. Let me introduce the management principles of sewage treatment equipment for you. The main principles of environmental management can be summarized as follows:
(1) Eliminate unreasonable products For some traditional waste products with low output value and difficult wastewater treatment, we should make up our minds to replace them with products with high output value and high technology content. If the annual profit of a certain product is not enough to cover the cost of treating wastewater every year, such a product should be determined to stop production and replace it with a product that is less polluting and easy to treat.
(2) Strengthening management and reducing pollution Enterprise management is also an important factor in preventing and controlling pollution. Such as running, running, dripping and leaking of equipment; production accidents or product scrapping caused by non-compliance with operating procedures; production of a large amount of high-concentration wastewater; flushing equipment and ground with a large amount of water, resulting in an increase in the amount of wastewater; cooling water Failure to achieve "clear and turbid diversion" with production wastewater will increase the amount of wastewater and the difficulty of wastewater treatment.
(3) For the establishment of regional small sewage treatment plants where factories are concentrated, it is not necessary to apply the principle of "who pollutes, who controls", but should strengthen the liaison between enterprises, and consider the pollution control measures as a whole, if necessary. If possible, the wastewater of each factory can be centrally treated, a unified sewage treatment plant can be established, and the treatment method of "who pollutes, who pays" can be implemented. Because each factory has different products, the quality of wastewater is not the same. For example, the wastewater of some factories is acidic, while the wastewater of some factories is alkaline. Treating them together can reduce the treatment cost of neutralizing agents. ; Some factories discharge wastewater with high salinity and low COD, while the wastewater from some factories is highly concentrated and easily biodegradable. If they are treated separately, they are all wastewater that is very difficult to treat, but if they are put together for biochemical treatment , Due to the improvement of water quality conditions, it can not only reduce the difficulty of wastewater treatment, but also improve the treatment efficiency.
(4) Improve the recycling rate of water In order to reduce the amount of waste water, we should first make a fuss about the source of waste water. For example, water recycling or multiple reuse can be considered to improve the water recycling rate and minimize external drainage. In foreign countries, the water recycling rate of some advanced enterprises has reached more than 96%, while the water recycling rate of Shanghai production enterprises is still at a low level of 20%, and there is still great potential. can be excavated. Improving the recycling rate of production water can not only reduce environmental pollution, but also reduce the amount of fresh water supplementation, which can alleviate the increasingly tense water resources problem to a certain extent. In wastewater treatment, the recycling of treated effluent should also be considered as much as possible.
(5) The pollutants in the recycling and comprehensive utilization of wastewater are all raw materials, semi-finished products, finished products and reaction media (such as solvents) that enter the water during the production process, especially some chemical reactions in fine chemical production are often not very reliable. The separation process of the product cannot be completely complete, so the wastewater, especially the reaction mother liquor, often contains a certain amount of useful substances. Emission of these pollutants will pollute the environment and cause harm. However, if it is recycled or comprehensively utilized, it can turn waste into treasure and harm into profit; or treat waste with waste, learn from each other's strengths to make up for one's shortcomings, and comprehensively manage them, which can save the cost of water treatment.
