Its test result, after using agent of sewage disposal of biology of carapace god ocean and technology of flood body rehabilitate, build good oxygen biology to stabilize a bed, processing sewage effect is apparent, expression is: Black smelly sewage is rapid decolour, deodorization, become clear, insipidity, the COD after handling two days by 333 drop 76, achieve view and admire water and the water quality demand that breed water, can develop aquatic substance. A green alga, red snapper grows to feed after 4 days wait for primary live thing, breed the water biology such as water hyacinth to be able to put in a suitable place to breed view and admire a fish.

其试验结果，运用甲壳神海洋生物污水处理(通过物化方法去除水中一些物质的过程)剂和大水体修复技术后，建立好氧生物稳定床，处理污水效果明显，表现为：黑臭的污水迅速脱色、脱臭，变得澄清、无味，处理两天后COD由333下降到76，达到观赏水和养殖水的水质要求，可培养水生物。4天后长出绿藻、红鱼食等初级生物，养殖水葫芦等水生物并可放养观赏鱼。

Some conclusions were drawn: Oenanthe javanica grew normally when TN and TP concentrations in raw water were 7.05-9.99 mg/L and 0.29-0.73 mg/L respectively; with the hydraulic load being 0.5 m^3/(m^2d), the removal rates of NH3-N, TP, and TN from heavily polluted river water by Oenanthe javanica floating bed were positively related to water temperature, and it inhibited the growth of algae stably; the mean removal rate of nutritive salt increased with the concentration of raw water.

研究结果表明，进水ρ和ρ分别为7.05~9.99mg/L和0.29~0.73mg/L，水芹菜能正常生长，在水力负荷为0.5立方公尺/的条件下，水芹菜浮床对重污染河水中的NH3-N，TP，TN的去除率与水温正相关，对藻类的抑制作用稳定；营养盐的去除负荷随原水质量浓度的增加而增大。

With retention time prolonged, the concentrations of TN, NH4(superscript +)-N and TP of domestic sewage were obviously reduced in all floating-bed systems, however the NO4(superscript +)-N concentrations were gradualjy accumulated due to the stronger nitrification than denitrification. The plants in floating-bed system increased significantly the N2O flux, which was 174.44μg/(m^2h), 82.19μg/(m^2h), 112. 49μg/(m^2h) and 44.81μg/(m^2h), respectively, for the Lolium mutliflorum, Oenanthe javanica, Vetiveria Zizanioides arid none-plant floating-bed systems.

净化周期内，浮床各系统的TN、NH4-N和TP浓度随着污水停留时间的延长直线下降，而NO3-N浓度却因系统内硝化强度大于反硝化强度而产生了累积；植物的存在明显的促进了浮床系统的N2O排放，浮床黑麦草、水芹、香根草和对照系统N2O的平均排放通量分别为174.44μg/， 82.19μg/， 112.49μg/和44.81μg。

The plant floating-bed technology application in Miaojia river showed that the water quality of the plant foating-bed technology applied had preceded evidently than the comparing water, though the water quantity was exchanged largely. There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.

植物浮床技术在苗家河的示范应用研究说明：在水量交换较大的情况下植物浮床技术仍然使示范河段水质优于对照段；浮床植物根际区存在着以有机颗粒、藻类、浮游动物、底栖动物为网络骨干的根系微生态系统：&水芹菜-水蕹菜&浮床模式可实现四季净化污染河水的周年运转，在后续应用中推荐使用此模式。

The fixed double chamber bed demineralizing equipment is developed by our country alone.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
