Embodiment 1

[0022] This embodiment is the application of Clematis aureus to treat rural combined domestic sewage. The specific application method is as follows:

[0023] 1. Rural combined domestic sewage pretreatment

[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 is easy to block the wetland system, causing hypoxia inside the wetland system and affecting the purification capacity of the wetland system. In order to reduce the clogging effect of particulate matter in wastewater, before entering the wetland system, the wastewater is first settled and filtered to remove the sediment and floating large particles in the wastewater.

[0025] In order to ensure the effect of wastewater pretreatment, it is required that the residence time of wastewater entering the sedimentation tank is 3 hours, and the grid gap is 0.5-1cm.

[0026] 2. Construction of artifici...

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 an application of artificial wetland plants to purify rural combined domestic sewage. Background technique [0002] With the rapid development of agriculture in my country, rural living standards have improved significantly, and the discharge of rural sewage and wastewater 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 less than 1%. In addition, the rural terrain is complex and the layout is scattered, which makes it difficult to collect and treat it like urban sewage. The random discharge of rural sewage and wastewater is one of the main reasons for the pollution of rivers, lakes, groundwater and other water environments. The problem of rural pollution is becoming more and more serious, and rural environmental pollut...
