Embodiment 1

[0031] Embodiment 1: as figure 1 As shown, the entire process system is that the flushing water of the urinal and the urinal is pretreated by the three-stage septic tank 16 and collected with the flushing sewage, and then enters the sedimentation tank 17, and the effluent of the sedimentation tank 17 flows into the artificial wetland 18 with filter cloth to prevent clogging, and finally flows into the Reservoir 19, to achieve the purpose of reuse. In addition, the sludge in the tertiary septic tank 16 enters the ecological drying filter bed 20 for treatment, and can be used as farmland fertilizer after treatment.

[0032] Such as figure 2 As shown, the flushing water of the urinal and urinal enters the three-stage septic tank 16, the effluent treated by the three-stage septic tank 16 enters the sedimentation tank 17, and the sludge enters the ecological drying filter bed 20.

[0033] Such as image 3As shown, the sedimentation tank 17 can store a certain amount of water to...

Abstract

The invention relates to a green recycling constructed wetland treatment system for treating toilet excrement and urine. The system consists of a three-stage septic tank, a sedimentation tank, an anti-blockage composite flow constructed wetland with filter cloth, and an ecological drying filter bed. After pretreatment by the three-stage septic tank, flushing water of closet pans and urinals joinswith flushing sewage to be collected, the mixed water enters the sedimentation tank, and effluent from the sedimentation tank enters the anti-blockage composite flow constructed wetland with filter cloth and finally flows into a reservoir for recycling. In addition, sludge from the septic tank enters the ecological drying filter bed for treatment, and can be used as farmland fertilizer after treatment. The green recycling constructed wetland treatment system has the advantages of high pollutant removal rate, stable operation of the system, recycling and harmless treatment of waste, recycling of resources, higher yield of the whole treatment system, and the like.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and relates to a green resource-based artificial wetland treatment system for toilet excrement treatment, especially suitable for small towns, rural areas, tourist attractions and buildings where people live together and are scattered, drainage pipe networks are incomplete, and sewage Areas where treatment systems are lacking. Background technique [0002] The method of collecting feces and urine sewage through the drainage pipe network and then transporting it to the sewage treatment plant for treatment not only increases the treatment load of the sewage treatment plant, but also is not feasible for urban suburbs and rural areas where the municipal drainage network is not well developed. Therefore, in-situ treatment of feces and urine sewage is an effective method. Constructed wetlands can be constructed on the spot with local materials, which not only greatly reduces the investment in ...
