Movable micro electrolysis wetland sewage treatment method and system

Abstract

The invention provides a movable micro electrolysis wetland sewage treatment method and a movable micro electrolysis wetland sewage treatment system. The system comprises a pretreatment unit (1), a down-flow enhanced wetland region (2) in which a graphite particle anode electrolytic tank (18) is arranged, an electrolysis enhanced dephosphorization region (3) provided with a scrap iron anode electrolytic tank (19), and an up-flow denitrification enhanced wetland region (4) designed with a scrap iron anode electrolytic tank (20), which are used for removing suspended solids, organic matters / ammonia nitrogen, phosphides and nitric nitrogen respectively, wherein the electrolytic tanks are independent push-pull draw boxes, and are connected with a low-voltage stabilized voltage supply (14); a light fiber ball filter material is taken as a wetland bed filler. The system is provided with movable rollers (11). The invention develops a set of sewage treatment method and system which have the advantages of easiness, convenience, practicability, high efficiency, economical efficiency, beautifying of the environment and scattered on-site treatment aiming at the characteristics of economic backwardness, scattered distribution of sewage sources and the like of rural areas.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a mobile micro-electrolysis wetland sewage treatment method and system. Background technique [0002] In recent years, in order to promote the process of urbanization and improve the quality of life of rural residents, rural water supply projects have been gradually implemented. However, rural drainage projects have been neglected. Most of the rural domestic sewage is directly discharged into rivers or outdoor open spaces without any treatment. Later, it was allowed to infiltrate into the ground, and a small part infiltrated into the ground after simple treatment in septic tanks, seriously polluting surface water and groundwater. The shortage of water resources and water pollution seriously restrict the healthy and sustainable development of my country's national economy. The lagging infrastructure and low management level have inhibited the improvement and improvement...

Problems solved by technology

[0007] Constructed wetlands are relatively low in construction costs, simple in operation and maintenance, and have a good removal effect on organic matter and ammonia nitrogen. However, due to the limitation of oxygen environment and carbon source conditions, the removal effect of total nitrogen is affected, and the wetland matrix has a low adsorption capacity for phosphate. The removal of phosphide in sewage by constructed wetlands; the electrolysis method can effectively remove phosphate in sewage, and has the potential to provide electron donors under low-carbon source conditions, but this technology consumes a lot of energy, operating costs and equipment requirements are very high, not suitable for vast rural areas
