Governance of black and odorous water bodies in Henan Province, improving water environment governance capacity and winning the battle to govern black and odorous water bodies

Henan Black and Odorous Water Treatment. Black and odorous water bodies refer to the phenomenon of water pollution caused by urbanization, discharge of domestic sewage, etc., resulting in unpleasant odors and harm to the environment and human health. The treatment of black and odorous water bodies has always been an important task in environmental protection and urban construction.

Henan's treatment of black and odorous water bodies should start from the source, reducing the discharge of various pollutants. This requires various methods, such as improving production processes and strengthening pollutant control, to reduce the amount of pollutant discharge. At the same time, it is necessary to strengthen the supervision of sewage discharge units, punish illegal and unlawful acts, and ensure the effectiveness of source management. For water bodies that have already been polluted, scientific restoration techniques are needed to restore their ecological environment and water quality. The key to water body restoration is to break the cycle between water pollutants and sediments, aquatic plants, etc., remove sediments such as bottom mud and sludge, restore the growth of aquatic plants, and improve the self-purification capacity of water bodies.

In Henan's treatment of black and odorous water bodies, ecological restoration is an important technology. By improving water quality and protecting wetlands, etc., it promotes the restoration and development of the coastal ecosystem and builds a stable ecosystem. At the same time, it utilizes the self-purification function of the aquatic ecosystem to promote water quality improvement. Treatment should adopt a comprehensive approach, that is, starting from multiple aspects, adopting multiple technical means, and comprehensively using various treatment measures to achieve the treatment goals. Comprehensive treatment includes multiple aspects such as source reduction, water body restoration, and ecological restoration, and treatment methods include various technical means such as biological, physical, and chemical methods.

In Henan's treatment of black and odorous water bodies, social participation is an important means. It is necessary to widely mobilize social forces to participate in the treatment work, strengthen citizens' environmental awareness, and actively promote the development of the treatment work. At the same time, it is necessary to strengthen communication with residents, deeply promote environmental education, and allow the public to participate in the treatment work. The treatment of black and odorous water is a long-term project that requires cooperation from enterprises and all sectors of society. Only with the joint efforts of all parties can the goal of treating black and odorous water bodies be truly achieved, protecting the ecological environment and the health of the people.

The treatment of black and odorous water bodies in Henan is an important task in the current environmental protection field, but this work is not easy and requires overcoming multiple difficulties to be successfully completed. Let's take a look at the difficulties and challenges faced in the treatment of black and odorous water bodies. Some pollution sources are not easy to find, and some pollution sources may be isolated in a certain area or buried deep in the sewer lines. Identifying these pollution sources is very difficult. It is not simply a matter of removing odors, but also treating various impurities and bacteria in the sewage, directly reducing reuse, which is very difficult. The treatment of black and odorous water bodies requires huge investment, which requires a large amount of financial support. However, due to various reasons, the financial input in many areas has not yet reached the required level, and the treatment task can only be slowly advanced.

The treatment of black and odorous water bodies in Henan is a very arduous task that requires participation and support from multiple parties. To overcome these difficulties, it is necessary to continuously improve various management measures, strengthen technological research, and strengthen capital investment, so as to gradually promote the treatment of black and odorous water bodies and contribute to ecological environmental construction.
