In today’s society, with the rapid development of animal husbandry, pig farming industry is also growing. However, the problem of pig manure wastewater treatment is becoming increasingly prominent. How to treat the wastewater in the pig farm to meet the standards has become an urgent problem to be solved. This article will introduce in detail the views of pig farm management experts on the treatment of pig manure wastewater, as well as how to achieve zero emission solutions.
- Sources and characteristics of pig manure wastewater
Pig manure wastewater mainly includes pig excrement, flushing water, slaughter wastewater, etc., which contain a large amount of organic matter, ammonia nitrogen and other harmful substances. If it is directly discharged without treatment, it will cause serious pollution to the environment. Therefore, understanding the source and characteristics of pig manure wastewater is a prerequisite for treating wastewater.
- Pig manure wastewater treatment technology
At present, pig manure wastewater treatment technology mainly includes physical method, chemical method, biological method, etc. Among them, biological method has become the main means of pig farm wastewater treatment due to its environmental protection and high efficiency. Common biological methods include aerobic biological method, anaerobic biological method, etc. In addition, new treatment technologies such as membrane separation technology and advanced oxidation technology are also gradually being applied to the treatment of pig manure wastewater.
- Zero emission solution
Zero emission means completely removing pollutants from pig farm wastewater to achieve zero emission standards. To achieve zero emission, we need to start from the following aspects:
Improve the management system: Establish a sound wastewater management system, standardize the wastewater treatment process, and ensure the normal operation of wastewater treatment facilities.
Reasonable site selection and design: Select a suitable site to build wastewater treatment facilities to ensure that the design of the facilities meets environmental protection requirements and facilitates subsequent maintenance and management.
Scientifically select treatment technology: According to the characteristics of pig farm wastewater, scientifically select treatment technology to ensure that the wastewater treatment effect meets the standards.
Reasonable use of resources: In the process of wastewater treatment, attention should be paid to the recycling and utilization of resources, reducing treatment costs and improving economic benefits.
Summary: The zero emission method for pig manure wastewater treatment needs to start from management systems, site selection design, treatment technology, resource utilization and other aspects. Through scientific and reasonable measures, we can achieve efficient treatment of pig farm wastewater, reduce environmental pollution risks and improve economic benefits. As pig farm management experts, we should actively promote the concept of zero emissions and contribute to the sustainable development of animal husbandry.
