What Sewage Equipment is Needed to Solve the Sewage in New Rural Construction?
2025-03-12
In recent years, as China's new rural construction surges forward, the improvement of the rural living environment has become a top priority. Among the various environmental challenges, sewage treatment has emerged as a focal point. To effectively tackle rural sewage issues, a diverse range of advanced sewage treatment equipment has been introduced and put to use, playing a pivotal role in purifying rural water sources and enhancing the overall ecological environment.
One of the most commonly employed sewage treatment devices in rural areas is the septic tank. This relatively simple and cost - effective apparatus functions by guiding sewage into a sealed tank. Here, solid waste settles at the bottom and undergoes anaerobic digestion. The liquid portion, after undergoing a certain degree of treatment, gradually seeps into the soil. Ideal for individual households or small - scale rural settlements, septic tanks can effectively reduce the organic matter content in sewage to a certain extent. Their installation and maintenance are also straightforward.
Integrated sewage treatment equipment is another crucial component. This type of equipment integrates multiple treatment processes, including biological treatment, sedimentation, and disinfection, into a single compact unit. Take the A/O (Anoxic/Oxic) integrated sewage treatment equipment as an example. In the anoxic zone, anaerobic bacteria break down large - molecular organic matter, while in the oxic zone, aerobic bacteria further decompose the remaining pollutants. With the ability to handle a large volume of sewage, high treatment efficiency, and excellent effluent quality, integrated equipment meets the discharge standards for rural domestic sewage. It is frequently utilized in rural centralized sewage treatment projects, such as in village - level public areas or larger - scale rural residential communities.
The membrane bioreactor (MBR) equipment has also found its way into rural sewage treatment. MBR technology combines membrane separation with biological treatment. The membrane filtration system in MBR can effectively intercept suspended solids, bacteria, and even some viruses in sewage, resulting in extremely high - quality treated water. This treated water can be reused for irrigation or other non - potable purposes in rural areas. Despite its relatively high initial investment cost, the advantages of MBR equipment in terms of water quality and space - saving make it an attractive option for rural areas with high water reuse requirements and limited land resources.
Sewage pumps are also essential in the sewage treatment process. These pumps are responsible for transporting sewage from various sources, such as households and public facilities, to the treatment equipment. Different types of sewage pumps, such as submersible sewage pumps and self - priming sewage pumps, are selected based on the actual situation of the sewage source, including the transportation distance and sewage characteristics. They ensure the smooth flow of sewage throughout the treatment system.
Aeration equipment is an indispensable part of many sewage treatment processes. In biological treatment systems, aeration equipment supplies oxygen to aerobic bacteria, which is crucial for their metabolism and the decomposition of organic pollutants in sewage. Common aeration equipment includes blowers and diffusers. The blower provides air, and the diffuser evenly distributes the air in the sewage treatment tank, creating a favorable aerobic environment for the growth and reproduction of microorganisms.
The utilization of these sewage treatment equipment in new rural construction has yielded remarkable results. Once - polluted rural water bodies are gradually becoming clear, and the surrounding environment has been significantly improved. The unpleasant smell of sewage in villages has dissipated, and the quality of life of rural residents has been enhanced. As new rural construction continues to advance, more advanced and suitable sewage treatment equipment will be developed and applied, continuously contributing to the creation of a beautiful rural environment.
