Embodiment 1
[0022] The present embodiment is the application of clematis to deal with the domestic sewage of the rural combined system, and the specific application method is as follows:
[0023] 1. Pretreatment of domestic sewage in the rural combined system
[0024] Rural combined domestic sewage contains a large amount of degradable particulate matter, sediment and other substances. If it directly enters the constructed wetland system, it will easily block the wetland system, cause oxygen deficiency inside the wetland system, and affect the purification capacity of the wetland system. In order to reduce the blocking effect of particulate matter in the wastewater, the wastewater is subjected to sedimentation and filtration treatment before entering the wetland system to remove the sediment and floating large particles in the wastewater.
[0025] In order to ensure the effect of wastewater pretreatment, the residence time of wastewater entering the sedimentation tank is required to be 3 ...

Abstract
The invention discloses an application of anoectochilus formosanus in treating rural combined domestic sewage, belonging to the field of wastewater treatment. The problem of rural combined domestic sewage pollution can be permanently solved by planting anoectochilus formosanus in the rural combined domestic sewage, absorbing pollutants such as NH4<+>-N, TN, TP and CODcr in the rural combined domestic sewage by making full use of anoectochilus formosanus, and using the perennation characteristic of anoectochilus formosanus. The application disclosed by the invention has the advantages of low investment, low running cost, good effect and simple and feasible operation. Harvested anoectochilus formosanus also can be applied to drug use, can be mainly used for treating difficult and complicated diseases such as lung heat cough, hemoptysis of pulmonary tuberculosis, hematuria, febrile convulsion of children, tetanus, nephritis edema, arthralgia due to wind-dampness, traumatic injury, poisonous snake bite, bronchitis, urocystitis, diabetes, hematuresis, acute or chronic hepatitis, rheumatoid arthritis and tumor, and also can be used for removing acnes. An operation mode that conventional ecological engineering depends on government to invest money all the year around can be expected to change by treating wastewater by using anoectochilus formosanus and combining environmental protection with economic construction, and thus the application has profound significance.
Description
technical field [0001] The invention relates to the field of rural combined domestic sewage treatment, in particular to the application of an artificial wetland plant to purify rural combined domestic sewage. Background technique [0002] With the rapid development of agriculture in our country, the living standard of rural areas has improved significantly, and the discharge of sewage and wastewater in rural areas has also increased significantly. According to statistics, in 2007, the total amount of rural sewage discharge in my country has exceeded 9 billion tons, but the actual treatment rate is still less than 1%. In addition, due to the complex terrain and scattered layout in rural areas, it is difficult to centrally collect and process sewage like urban sewage. The random discharge of rural sewage is one of the main reasons for the pollution of rivers, lakes, groundwater and other water environments. The problem of rural pollution is also becoming more and more seriou...
