China’s rural sewage has the characteristics of large fluctuation of water quality and quantity, low carbon-nitrogen ratio, and low treatment efficiency of traditional processes at low temperature, which is difficult to meet the treatment needs. In this study, Microbial Immobilization Technology (MIT) was used to prepare immobilized biological fillers to improve the operation stability and treatment efficiency of the system under low temperature conditions. Based on the existing rural sewage col...

This study evaluates the impact of geographic source variation of Burnt Pulverized Chikoko (BPC) clay on the compressive strength characteristics of concrete Chikoko clay was sourced from Okrika (Rivers State) and Ogbia (Bayelsa State), both in the Niger Delta region of Nigeria, and processed through calcination into BPC. The material was incorporated as an admixture in concrete at varying proportions (0%, 5%, 10%, 15%, and 20%) using two mix ratios (1:1.5:3 and 1:2:4) with a constant water ceme...

Red clay is prone to stability problems in engineering due to its high porosity ratio, strong hydrophilicity, and high sensitivity of strength to water content. Traditional improvement materials (such as cement and lime) have significant effects but suffer from drawbacks like high energy consumption, high carbon emissions, and environmental damage. To explore a green and sustainable soil improvement method, this study selected three biopolymers—xanthan gum, guar gum, and carrageenan—as modifiers...
