Abstract

Received: 28 November 2020 Accepted: 10 February 2021 This paper aims to improve the treatment effect of the multi-soil-layering system (MSL) on rural domestic wastewater. For this, sludge-based biochar materials were selected in the experiments to study its impacts on the treatment of rural domestic wastewater using the MSL. The comparative experiments were conducted for the three MSL systems filled with different materials: the sludge-based biochar (a), wood chips (b), and charcoal (c). The results showed that when the sludge-based biochar material was used as a filler, the removal effect of COD, NH4-N, TN, TP is better than that of wood chips and charcoal, and the removal rates were 80%, 90%, 65% and 92%, respectively, meeting the Grade A standard specified in the Hebei Province Rural Domestic wastewater Discharge Standard (DB13/2171-2015); hydraulic loading rates (HLRs) have a great impact on the removal of pollutants, and the pollutant indicators in the system (a)re affected by the HLRs in different degrees, i.e., NH4-N>TP>COD>TN from high to low; considering the treatment efficiency and pollutant removal effect, the HLRs should be selected between 800L/(m·d) and 1200L/(m·d). It’s concluded finally that the sludge-based biochar material can strengthen the removal effect of the MSL system. This study is of theoretical value for the further research on MSL system and resource utilization of the sludge.

污泥基生物炭多层土壤系统处理农村生活污水的试验研究

本文旨在提高多层土壤系统(MSL)对农村生活污水的处理效果。为此，实验选择污泥基生物炭材料，研究其对MSL处理农村生活污水的影响。对填充不同材料的三种MSL体系进行了对比实验:结果表明:污泥基生物炭(a)、木屑(b)和木炭(c)作为填料时，对COD、NH4-N、TN、TP的去除效果优于木屑和木炭，去除率分别为80%、90%、65%和92%，达到《河北省农村生活污水排放标准》(DB13/2171-2015)规定的a级标准;水力加载率(HLRs)对污染物去除率影响较大，系统中的污染物指标(a)受水力加载率的影响程度不同，NH4-N>TP>COD>TN由高到低;综合考虑处理效率和污染物去除效果，hlr宜选择在800L/(m·d) ~ 1200L/(m·d)之间。最后得出结论，污泥基生物炭材料可以增强MSL系统的去除效果。本研究对MSL系统的进一步研究和污泥资源化利用具有一定的理论价值。

期刊介绍： The ACSM is concerning the cutting-edge innovations in solid material science. The journal covers a broad spectrum of scientific fields, ranging all the way from metallurgy, semiconductors, solid mineral compounds, organic macromolecular compounds to composite materials. The editorial board encourages the submission of original papers that deal with all aspects of material science, including but not limited to synthesis and processing, property characterization, reactivity and reaction kinetics, evolution in service, and recycling. The papers should provide new insights into solid materials and make a significant original contribution to knowledge.
