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...

Examples

Embodiment Construction

[0034] The specific implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0035] The sewage is preliminarily settled and filtered in the pretreatment unit 1 to remove suspended solids in the sewage, and the bottom sediment can be regularly removed through the mud discharge hole 7 .

[0036] The pretreated sewage is lifted through the water inlet pipe 9 under the action of the water inlet pump 12, and flows through the downflow enhanced wet area 2. The unsaturated state of this area ensures that the wetland bed has a good oxygen environment, and at the same time, the bottom is permanently submerged. The oxygen generated by the graphite particles in the graphite particle anode electrolytic cell 18 under the action of curre...
