Recyclable sewage treatment system and process for mobile environment-friendly toilet

Abstract

The invention relates to the field of environment-friendly toilets, an electrochemical method and a biological method are utilized to achieve zero emission and recycling of toilet sewage, scum and sediment generated in the system are collected and then automatically pressed into a mud cake through a volute filter press, and the mud cake is treated as solid waste after being dried in the air. The invention particularly relates to a recyclable sewage treatment system and process for a mobile environment-friendly toilet. According to the main principle, macromolecular chains in sewage are brokenand degraded under the electrocoagulation and electrocatalysis action of an electrocoagulation module, meanwhile, chloride ions in the water can be excited and converted into hypochlorous acid and thelike in the electrocatalysis process to thoroughly kill bacteria, viruses and microorganisms in the water, and the treated effluent can be used for flushing toilets. The system and the process are adopted for treating the toilet sewage of the field construction operation unit without the town sewage pipe network and have the advantages that water resources are saved, environmental pollution is reduced, and the system and the process are particularly suitable for treating the toilet sewage of the field construction operation unit without the town sewage pipe network; modular overall equipmentis small in occupied area and easy and convenient to maintain; compared with a technology for treating toilet sewage by a biological method, the cost is greatly reduced, and the effect is excellent.

Description

technical field

[0001] The invention relates to the field of environmentally friendly toilets, and is particularly suitable for toilet sewage treatment in field construction units without urban sewage pipe networks. Specifically, it relates to a recyclable sewage treatment system and process for mobile environmentally friendly toilets. Background technique

[0002] The scarcity of water resources has become a social problem, especially in the northern part of our country. Saving water and reducing the waste of water resources have become the consensus of the whole society.

[0003] Environmentally friendly toilets refer to water saving, energy saving, on-site recycling and reduction of human waste. At present, the traditional water circulation flushing toilet is to flush the dirt after using the toilet with water, and then rely on bioengineering methods to process the feces and flushing water discharged from the toilet, and the treated water is used as toilet flushing water ...
