Food wastewater treatment is an important topic in the field of environmental protection, which involves the protection of water resources, the maintenance of human health and the maintenance of ecological balance. With the rapid development of the food industry, the amount of wastewater generated is increasing, and how to effectively treat these wastewater has become an urgent task in front of us. This article will introduce the current situation, problems and solutions of food wastewater treatment in detail, in order to provide a useful reference for solving the problem of food wastewater pollution.
1. Current status of food wastewater treatment.
Food wastewater is mainly used in food processing, cleaning and washing in the production process. These wastewaters contain a large amount of harmful substances such as organic matter, grease, suspended solids, and pathogenic microorganisms that may be present. Traditional food wastewater treatment methods include physical, chemical and biological methods. The physical method mainly removes suspended solids in wastewater through sedimentation and filtration; The chemical method uses the addition of chemical agents to make the harmful substances in the wastewater react chemically, so as to achieve the purpose of removal; The biological law is to use the metabolic action of microorganisms to decompose the organic matter in the wastewater into harmless substances.
However, there are still many problems with existing food wastewater treatment methods. First of all, the treatment effect is unstable, and it is difficult to achieve the ideal treatment effect. secondly, the processing cost is high, which is difficult for some small food businesses to afford; In addition, secondary pollution may occur during the treatment process, posing a potential threat to the environment and human health.
Second, the problem of food wastewater treatment.
1.Backward treatment technology: At present, many food companies still use traditional wastewater treatment methods, which are not only inefficient, but also difficult to meet environmental requirements. With the development of science and technology, new wastewater treatment technologies are emerging, but these technologies still face many difficulties in practical application, such as high technical threshold and large equipment investment.
2.Lack of environmental awareness: Some food companies lack environmental awareness and do not pay enough attention to wastewater treatment. In order to maximize profits, some enterprises often ignore the wastewater treatment process, resulting in direct discharge of wastewater and serious environmental pollution.
3.Insufficient supervision: In some areas, environmental protection regulators have insufficient supervision over food wastewater treatment, resulting in illegal wastewater discharge by enterprises. In addition, there is insufficient communication and coordination between regulatory authorities, which is prone to regulatory gaps, which brings difficulties to wastewater treatment.
3. Solutions for food wastewater treatment.
1.Promote new wastewater treatment technologies: In view of the shortcomings of existing wastewater treatment technologies, the research and development and promotion of new wastewater treatment technologies should be increased. For example, new technologies such as advanced oxidation technology and membrane separation technology have the advantages of good treatment effect and fast treatment speed, which can effectively solve the problem of food wastewater treatment. At the same time, we should increase support for environmental protection technology innovation, encourage enterprises to adopt new technologies and new processes, and improve the efficiency of wastewater treatment.
2.Improve corporate environmental awareness: Food enterprises should fully realize the importance of wastewater treatment, strengthen environmental awareness education, and improve employees' environmental awareness. At the same time, enterprises should strengthen internal management, establish a sound wastewater treatment system, and ensure the normal operation of wastewater treatment facilities and the discharge of wastewater up to standard.
3.Strengthen supervision: Environmental protection supervision departments should strengthen the supervision of food wastewater treatment, increase law enforcement, and crack down on enterprises that illegally discharge wastewater. At the same time, the regulatory authorities should strengthen communication and coordination to form a joint force to jointly promote the treatment of food wastewater. In addition, it is also necessary to establish and improve the wastewater treatment supervision system, improve relevant laws, regulations and standards, and provide a strong guarantee for wastewater treatment.
4. Conclusions and prospects.
Food wastewater treatment is a long-term and arduous task, which requires the joint efforts of enterprises, enterprises and all sectors of society. By promoting new wastewater treatment technologies, raising corporate awareness of environmental protection and strengthening supervision, we can effectively solve the problem of food wastewater treatment and protect water resources and the ecological environment. In the future, with the advancement of science and technology and the improvement of environmental awareness, we believe that the treatment of food wastewater will achieve more significant results and contribute to the sustainable development of mankind.
