Abstract

The invention discloses a composting sewage environmental-friendly recycling system. An artificial permeation pond is constructed, water is subjected primary filtration and purification through a river impact sand layer and a marble sand layer in the artificial permeation pond, toxic substances in the water are subjected to further adsorption treatment through an activated carbon layer at the bottom of the artificial permeation pond, finally filtration treatment is implemented through a ceramic filtering membrane, then water quality meets a recycling degree, sewage can be immediately used after multiple steps of purification treatment, and difficulties of factory shutdown, agricultural yield reduction and the like caused by water shortage can be alleviated; due to adoption of silicon carbide, the ceramic filtering membrane can form a cordierite phase, due to adoption of cerium oxide, formation of spinel can be inhibited, the silicon carbide and the cerium oxide are capable of synergistically increasing the resultant force of a granule neck structure, uniform pore size distribution can be achieved, and the filtration efficiency of the ceramic filtering membrane can be improved; in addition, due to adoption of nano titanium dioxide and nano silica, the ceramic filtering membrane has an antibacterial and sterilization function, and the sewage purification capability of a system can be further improved.

Description

technical field [0001] The invention relates to an environment-friendly recycling system for composting sewage. Background technique [0002] Water pollution is water that reduces or loses the use value of water caused by harmful chemicals and pollutes the environment. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic in sewage, organic poisons such as benzene, dichloroethane, and ethylene glycol, will kill aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in the sewage is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing hydrogen sulfide, mercaptan and other unpleasant gases, which further deteriorates the water quality. Over the years, the quality of China's water resources has continued to decline, the water environ...
