Embodiment 1

[0022] This embodiment is the application of varnish to treat rural combined domestic sewage, and 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 artificial w...

Abstract

The invention discloses application of euphorbia helioscopia in treatment of countryside combined system domestic sewage, belonging to the field of wastewater treatment. Euphorbia helioscopia is planted in the countryside combined system domestic sewage and is fully used for absorbing pollutants of NH4<+>-N, TN, TP, CODcr and the like in the countryside combined system domestic sewage, and with the perennial characteristic of euphorbia helioscopia, the problem of pollution caused by the countryside combined system domestic sewage is solved permanently. The application of euphorbia helioscopia has the advantages of less investment, low running cost, good effect and simple and feasible operation. The harvested euphorbia helioscopia can also be medically used to mainly treat hydropneumatosis, phlegm retention asthmatic cough, malaria, bacillary dysentery, scrofula, ringworm sores, tuberculous fistula and osteomyelitis. By using the treated wastewater, environmental protection is combined with economic construction, the operation mode that the conventional ecological engineering depends on government investment funds year after year is expected to be changed, and the significance is far-reaching.

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 pollu...
