Abstract
Rural sewage collection systems are important parts of rural sewage engineering and the conditions in underdeveloped mountainous areas are not conducive to the construction and operation of conventional rural sewage collection systems. This study investigated and analyzed the practical rural sewage collection system in an underdeveloped mountainous area, and found that the diameters of the public rural sewers in the region were mostly DN300 and DN500, the relative depth was generally <0.3, and the frequency of siltation was 6 %. The concentration of chemical oxygen demand (COD), suspended solids (SS) and ammonia nitrogen in the rural sewage collection system was relatively high, and the pollution degree of the sewage could be reflected through the conductivity, turbidity, dissolved oxygen and oxidation reduction potential, so as to realize the rapid monitoring of the rural sewage characteristics and ensure the normal operation of the terminal treatment facilities. The removal capacity of COD and SS in sewers and ditches was different. It is suggested to strengthen the operation and maintenance of the collection system, optimize the design parameters of the collection system and evaluate the concentration of influent pollutants in the treatment facilities to improve the effectiveness of rural sewage treatment.
期刊介绍：
The Journal of Water Process Engineering aims to publish refereed, high-quality research papers with significant novelty and impact in all areas of the engineering of water and wastewater processing . Papers on advanced and novel treatment processes and technologies are particularly welcome. The Journal considers papers in areas such as nanotechnology and biotechnology applications in water, novel oxidation and separation processes, membrane processes (except those for desalination) , catalytic processes for the removal of water contaminants, sustainable processes, water reuse and recycling, water use and wastewater minimization, integrated/hybrid technology, process modeling of water treatment and novel treatment processes. Submissions on the subject of adsorbents, including standard measurements of adsorption kinetics and equilibrium will only be considered if there is a genuine case for novelty and contribution, for example highly novel, sustainable adsorbents and their use: papers on activated carbon-type materials derived from natural matter, or surfactant-modified clays and related minerals, would not fulfil this criterion. The Journal particularly welcomes contributions involving environmentally, economically and socially sustainable technology for water treatment, including those which are energy-efficient, with minimal or no chemical consumption, and capable of water recycling and reuse that minimizes the direct disposal of wastewater to the aquatic environment. Papers that describe novel ideas for solving issues related to water quality and availability are also welcome, as are those that show the transfer of techniques from other disciplines. The Journal will consider papers dealing with processes for various water matrices including drinking water (except desalination), domestic, urban and industrial wastewaters, in addition to their residues. It is expected that the journal will be of particular relevance to chemical and process engineers working in the field. The Journal welcomes Full Text papers, Short Communications, State-of-the-Art Reviews and Letters to Editors and Case Studies
