Middle water inlet both sides water outlet form, middle inlet channel 9 width is 10-20cm (see Fig. 3).The narrower pool ridge is intake using unilateral,
Opposite side water outlet (see Fig. 1).Middle water inlet form is respectively arranged ecological treatment apparatus in inlet channel both sides, and unilateral water inlet form is then
Only arrange single ecological treatment apparatus.
2. string Tang Tang ridge eco-filtration processing meanss are placed on the pool ridge section hollowing out, according to pool ridge size single or multiple lift
Place；
3. string Tang Tang ridge eco-filtration processing meanss are banked up at the 20-30cm of Tang Geng road surface, in device both sides wood
Stake is fixing, then with batten, the timber 10 of device both sides is pind down fixation；
4. pour road surface or precoated plate 11 at string Tang Tang ridge eco-filtration processing meanss top, and the ecological mistake with the string Tang Tang ridge
5-10cm space is reserved between filter processing meanss；
5. the filter bag for middle water distribution form then will all make filter bag in both sides, implementation steps identical (see Fig. 3)；
6. the structure of aerobic-weak oxygen-aerobic microenvironment：Current are made to flow to water side by the water inlet end of eco-filtration band, profit
Form microbial environment, i.e. the first zeolite with nutrient substance in water body and carbon source in the eco-filtration processing meanss of the string Tang Tang ridge
Layer, the first bamboo-carbon layer, the second bamboo-carbon layer, the second zeolite layer interior formation aerobic environment, form weak oxygen environment in mixing filtering layer；
7. the plantation of higher aquatic plants：In eco-filtration band planted on two sides higher aquatic plants 12, on the one hand strengthening nitrogen
The absorption of the nutrient substance such as phosphorus removes, and on the other hand also beautifies the environment.
8. water circulation：Make string Tang Tang ridge both sides water circulation, pool water body purification is processed：Followed by controlling overall hydrodynamic force
Ring process, increases the time of staying of water body in defecator, can strengthen to pool under water circulation and not cycling condition
The process of water body.
Laboratory test preliminary treatment effect：
Laboratory test adopts vertical earth pillar device, the high 120cm of earth pillar, a diameter of 30cm.10cm is inserted in layering from bottom to up
Zeolite (diameter 1-2cm), 10cm bamboo charcoal (diameter 1-2cm), 2cm soil, 10cm zeolite (diameter 1-2cm), 10cm Ramulus Salicis Babylonicae,
The mixture of 10cm bamboo charcoal (diameter 1-2cm), 2cm soil, 10cm bamboo charcoal (diameter 1-2cm), 10cm zeolite (diameter 1-2cm).
It is relevant with the infiltration coefficient of aquiclude and filter bag size that unit area crosses Water l oad.Measured by laboratory test
The osmotic coefficient k of aquiclude, if eco-filtration band overall length be L, average cross water height be H, width be W, △ H be filter bag two
The head difference of side, then seepage discharge is Q=kLH △ H/W, and seepage velocity is u=k △ H/W, thus can obtain the mistake of unit area
Water l oad is q=k △ H/W, and the time of staying is T=W2/(k△H).
Earth pillar lower end intakes, upper end water outlet, and control Inlet and outlet water traffic load is 863L/ (h m2).Sewage takes from the Qinhuaihe River
Tributary, certain sewage treatment plant's blowdown mouth downstream 300m about section.Upper end water outlet accesses sewage storage pond, recycles.Simultaneously
Part water sample is taken to be placed in bucket as control sample.Device is continuous to be run 1 month, fetches earth in the water outlet of post upper end and bucket within every 5 days
Comparison water sample analysis CODMn、TN、NH4 +-N、NO3 -- N and TP.
Experimental result is shown in Fig. 4.According to this experimental result：This eco-filtration processing means is to the treatment effect of nitrogen relatively
Good, the treatment effect of wherein ammonium nitrogen is about 79%, slightly above corresponding control sample 76% (mainly the initial stage adsorption simultaneously
Be converted to nitrate nitrogen)；The removal effect of nitrate nitrogen has then reached more than 85%, and in corresponding control sample, nitrate omits on the contrary
There is rising；The removal effect of total nitrogen has equally reached more than 85% hence it is evident that being higher than the 19% of corresponding control sample.It can be seen that this process skill
Art can be effectively formed weak reducing environment, and the denitrogenation to the removal particularly nitrate nitrogen of nitrogen achieves preferable effect.Right
CODMnIt is respectively 57% and 67% with TP treatment effect, respectively higher than the 25% of control sample and 28%.Will shape after longtime running
Become effective biological membrane environment, strengthen the removal to pollutant such as COD and nitrogens further.This device is applied to the pool ridge on the string pool
Can permanently effective low cost movement, the treatment effect of strengthening fish pond waste water, face source runoff pollution etc., be effectively lifted into lake storehouse water body
Water quality.
