[0022] Example 1: Treatment of Domestic Sewage by Constructed Wetlands

[0023] like figure 1 and figure 2 and image 3 As shown, the constructed wetland system is set up, the flushing system includes drainage pump 3, main pipe 4, sewage cleaning branch pipe 5, water spray pipe 6 and water spray branch pipe 7, and the pollutant collection system includes drainage ditch 8, sewage cleaning ditch 9, and sludge discharge tank 10 and the water retaining plate 11; the drainage pump 3 pumps and drains the water purified by the wetland in the sump 2, enters the water spray pipe 6 through the main pipe 4, and then sprays out through the water spray branch pipe 7 to clean the phytoremediation block 12 filter layer 15 The pollutants filtered out in the sewage; through the flushing of the sewage branch pipe 5, the drainage ditch 8 collects the pollutants washed out into the sewage ditch 9, and finally enters the sludge discharge tank 10 for sedimentation. The sediment after sedimentati...

Abstract

The invention discloses an anti-blocking artificial wetland system which comprises a washing system and a pollutant collecting system. Due to reverse washing, particulate matter in a filter layer (15) in a phytoremediation block (12) is washed into a drainage ditch (8); due to washing of a sewage removal branch pipe (5), pollutants are washed into a sewage removal ditch (9) and flow into a mud discharge pond (10) to be precipitated, bottom mud obtained after precipitation is removed, sewage obtained after precipitation enters the artificial wetland system again through the drainage ditch (8) at a sewage inlet, a water baffle (11) is arranged at the junction of the drainage ditch (8) and the sewage removal ditch (9), in the wetland operation process, the water baffle (11) is turned off, and when sludge is washed, the water baffle is turned on. In the operation period of the whole system, connectivity of the filter layer is kept, the purpose that the wetland system is not blocked is achieved, the service life of the system is prolonged, and the operation cost of the system is lowered. The system is simple in technology, remarkable in effect and wide in application range.

Description

technical field [0001] The invention relates to the technical field of artificial wetland sewage treatment, which is applied to the treatment of domestic sewage or low-pollution water, and in particular relates to an anti-clogging artificial wetland system. Background technique [0002] At present, our country has a large population and produces a large amount of domestic sewage every day. Reducing the cost of sewage treatment has become a problem that is expected to be solved. In addition, although the low-pollution water after treatment in sewage plants meets the national standard requirements, the water quality is poorer than that of rivers, so it is low pollution. The discharge of water into the river will speed up the pollution of the river. As an effective method of sewage and low-pollution water treatment, constructed wetland technology plays an important role in the water treatment system. [0003] Constructed wetlands have the advantages of low cost and no secondar...
