Below in conjunction with accompanying drawing the utility model is described in detail.
See also Fig. 1, the sun power supplementary disinfection device of the combined artificial wetland of the utility model mainly is connected with level Four rising pipe 13 through one-level rising pipe 4, secondary effluent pipe 6, three grades of rising pipes 10 by the auxiliary sterilization pool C of settling pit A, one-level drowned flow artificial wet land B, sun power and secondary drowned flow artificial wet land D in order to be organized.Waste water gets into one-level drowned flow artificial wet land B behind settling pit A sedimentation and filtration; Water after handling through one-level drowned flow artificial wet land B gets among the auxiliary sterilization pool C of sun power, through the uv ray in the one-way vision mirror reflected sunlight to the waste water disinfection in the wetland.Water outlet after the sterilization is made further intensified process through secondary drowned flow artificial wet land D.
Say at length that again the sun power of the combined artificial wetland of the utility model is assisted the sterilisation system device, mainly is by settling pit, the one-level drowned flow artificial wet land, auxiliary sterilization pool of sun power and secondary drowned flow artificial wet land are formed in order; Wherein:
Settling pit A is a square pond body structure, and Chi Gai is not established at the top, and the water inlet pipe place is provided with I water inlet pipe valve 2; Be mainly used in the collection sewage; Waste water gets into settling pit through water inlet pipe 1, and stay for some time (such as 3 hours) are with removing big particle thing and inorganic suspended substance.One-level rising pipe 4 is located at the rear wall middle part of settling pit A, and II valve 3 is installed.Waste water gets into one-level drowned flow artificial wet land B through one-level rising pipe 4.
One-level drowned flow artificial wet land B is made up of cloth waterwall and bed body, does not establish top cover.The cloth waterwall accounts for 10% of a body length, highly is 1.0m, and water distribution is filled with the Wingdale that diameter is 30-60mm within the walls.Bed body middle lower portion is filled filler, and filler is the zeolite of 15-30mm and the combined stuffing of Wingdale (weight ratio of Wingdale and zeolite is 1: 1), and depth of packing is 0.6-0.9m, and total length is 90% of a pond body total length.The local advantage waterplant of bed body filler top plantation.Get into the cloth waterwall from one-level rising pipe 4 effusive waste water; The waste water that uniform distribution is crossed in the cloth waterwall stay for some time at Chi Tizhong (such as 1.5 hours); Flow into the auxiliary sterilization pool C of sun power through secondary effluent pipe 6 after removing pollutents such as nitrogen, phosphorus and organism, secondary effluent pipe 6 is installed III valve 5.
The auxiliary sterilization pool C of sun power mainly is made up of one-way vision mirror 8, swinging strut 7, three grades of rising pipes 10 and IV valve 9.Filler is not established in the auxiliary sterilization pool C body of sun power bottom, and three grades of rising pipes 10 are positioned at the medium position of the auxiliary sterilization pool C rear side of sun power.The auxiliary sterilization pool C of sun power both can be used as the braiding channel of one-level current wetland B, again can be simultaneously as the cloth waterwall of secondary drowned flow artificial wet land D.The waste water that gets into the auxiliary sterilization pool C of sun power from secondary effluent pipe 6 stays for some time (such as 2 hours), assembles the UV-light killing pathogenic bacteria through the angle reflection of rotating translucent mirror 8.Treated waste water gets into secondary drowned flow artificial wet land D through three grades of rising pipes 10.
Secondary drowned flow artificial wet land D is made up of bed body, cloth waterwall, level Four rising pipe 12 and V valve 11, does not establish top cover.Bed body middle lower portion is filled filler, and filler is the zeolite of 15-30mm and the combined stuffing of Wingdale (weight ratio of Wingdale and zeolite is 1: 1), and depth of packing is 0.6-0.9m, and total length is 90% of a pond body total length.The local advantage waterplant of bed body filler top plantation.The cloth waterwall accounts for 10% of a body length, highly is 1.0m, and water distribution is filled with the Wingdale that diameter is 30-60mm within the walls.From three grades of rising pipes, 10 effusive waste water entering secondary drowned flow artificial wet land D, stay for some time (such as 1.5 hours), strengthen removal pollutents such as nitrogen, phosphorus and organism.Getting into level Four rising pipe 12 through the cloth waterwall subsequently flows out.
The local advantage waterplant of plantation in above-mentioned one-level drowned flow artificial wet land and the secondary drowned flow artificial wet land, as: one or more of reed, Spiked Loosestrife and calamus, planting density 3-4 strain/m of plant 2
The auxiliary sterilization pool of the sun power of the utility model setting is an open base area, can fully contact with the external world, and be the waste water oxygenation again, remedied the shortcoming of post-processed pollutant dissolution hypoxgia greatly.
The auxiliary sterilization method of the sun power of the combined artificial wetland of the utility model is following:
1) the guiding sewage flows into the settling pit that can remove coarse particles and suspended substance;
2) the effusive water of settling pit flows into the one-level drowned flow artificial wet land through water inlet pipe, and stay for some time (such as >=1.0 hours), the interception suspended substance is removed part nitrogen, phosphorus, organism;
3) effusive water in the one-level drowned flow artificial wet land is introduced in the auxiliary sterilization pool of sun power, (such as >=1.5 hours) stay for some time.The sun power wavelength region is very wide, can be distributed in different-wavebands such as UV-light, visible light and infrared band, and is that ultraviolet ray between the 240-280nm has germicidal action at wavelength only, and is the strongest with wavelength 253.7nm place sterilizing ability especially.Therefore need to separate the long wavelength in the sunshine, assemble the short wavelength, concentrate sterilization.Like this just need reflect short wavelength's ray and see through long wavelength's ray through an one-way vision mirror.Make the uv ray of reflection all gather together, improve sterilisation effect wastewater disinfection.This stage mainly be by the ultraviolet ray in the sun power to wastewater disinfection, regulate the sewage water yield, be the sewage oxygenation again;
4) water outlet of the auxiliary sterilization pool of sun power flows into the secondary drowned flow artificial wet land, and stay for some time (such as >=3.0 hours), this section process mainly is to admit not removed organism, nitrogen, phosphorus etc. in the leading portion one-level drowned flow artificial wet land.Strengthen the removal of pollutent.
In sum, the sun power supplementary disinfection device of the combined artificial wetland that the utility model adopts has made full use of distributing flue and braiding channel between the two-stage wetland as sterilization pool, under the prerequisite that does not increase working cost, has improved the sterilisation effect of wetland greatly.
The sun power supplementary disinfection device of the combined artificial wetland of the utility model mainly contains three effects, the one, water distribution effect, regulating pondage; The 2nd, waste water is carried out multiple oxygenation, for subsequent disposal provides dissolved oxygen; The 3rd, sewage is concentrated sterilization, eliminate pathogenic bacteria harm, reduce wet land system and handle load.
Below lifting embodiment describes.
