Problems solved by technology

[0004] To conduct pollution analysis, it is necessary to collect samples from these media. Soil sample collection has mature technology, but water sample collection is still relatively chaotic. Most of them use scoops to scoop water directly. The most direct impact is the disturbance of zooplankton in the water body. , leading to inaccurate results

Embodiment 1

[0036] Such as Figure 1 ~ Figure 4 As shown, the present invention discloses a paddy field wetland water sample collection device and a water sample processing method, which includes a transparent glass container 1 with a diameter of about 10 cm and a height of at least 15 cm with one side opening, the container has a volume scale; the glass container is another One side has two water outlet holes 5, 6, both of which are close to the edge of the side wall of the transparent container 1, and in actual use, the outlet hole 6 is closer to the soil layer than the water outlet hole 5. The two water outlet holes 5 and 6 can be closed with a piston as required, and the material of the plug body is preferably frosted glass; the open end of each glass container 1 is provided with a funnel-shaped water inlet structure 2, and the water inlet structure 2 is fixed by a detachable The basket 3 is connected to the open end of the transparent container 1, and the end of the water inlet struc...

Embodiment 2

[0043] Such as figure 1 As shown, this embodiment includes as image 3 Perforated graduated glass containers shown, such as figure 2 fixed basket as shown, as Figure 4 Mounting bracket and mounting feet shown. The material selected for glass container 1 with scale is transparent glass with a diameter of about 10 cm and a height of at least 15 cm. The container is formed at one time without bonding materials, and the wall thickness is preferably 1 mm. It has a volume scale; the water sample to be measured is collected in the glass container 2, wherein figure 2 As shown, the fixed basket 3 wrapped in the glass container with a funnel-shaped lid with holes is preferably soft transparent plastic, and the material of the inner funnel-shaped part placed in the glass container is preferably soft transparent plastic, and the small hole is preferably a steel ring with a diameter of 2 cm, and a stopper can be used. cover. The fixed basket is used for the tested water sample to en...

Embodiment 3

[0046] In this example, the effect of 48% chlorpyrifos EC on plankton in paddy fields was studied. Chlorpyrifos is a high-efficiency, broad-spectrum organophosphorus insecticide, which is mainly used to control Lepidoptera, Coleoptera, Homoptera and other crops on rice, fruit trees, vegetables, cotton, wheat, soybeans, peanuts, tea, sugarcane and other crops. Order, Hemiptera pests and mites, thrips, etc. However, environmental toxicology studies have found that chlorpyrifos is potentially dangerous to the ecological environment. 50 It is 1.33mg / L, which belongs to poisonous pesticide; 50 (48h) less than 1.2μg / L, which belongs to highly toxic pesticides; EC to algae 50 (72h) is 20.79mg / L, belongs to low toxicity pesticide. Daphnia magna is a typical zooplankton, but there are few reports on the effects of chlorpyrifos on plankton in paddy fields. In view of this situation, this study collected paddy field water samples many times, and carried out qualitative and quantitati...

Abstract

The invention discloses a rice field wet land water sample collecting device. The rice field wet land water sample collecting device comprises a transparent container which is of a cylindrical structure with one end open and one end closed. A funnel-shaped water inlet structure is arranged at the open end of the transparent container, and one or more water outlets are formed in the closed end of the cylindrical structure. By means of the rice field wet land water sample collecting device, zooplankton and phytoplankton are free of the influence of artificial disturbance while the collection of a water sample, and the adverse influences generated on plankton after chemicals or pesticides are applied into a rice field can be easily observed, qualitatively observed and quantitatively measured. The rice field wet land water sample collecting device is high in operability, simple in structure and convenient to assemble, manufacture and maintain. The device can be used for measuring and detecting multiple sets of samples at the same time. The device is suitable for field water layer sampling with the water depth of 10 cm or deeper, it is ensured that the growth conditions of plankton are close to those in the outside world, and meanwhile the influences of chemicals and pesticides on plankton can be conveniently observed. The invention further discloses a rice field wet land collected water sample treating method.

Description

technical field [0001] The invention relates to a paddy field wetland water sample collection device and a water sample processing method, which are suitable for qualitative and quantitative detection of phytoplankton and plants by measuring pollutants such as chemicals and pesticides. Background technique [0002] Paddy fields play an important role in constructed wetlands. In 2015, the paddy area in my country was about 30.2132 million hm 2 (National Bureau of Statistics of the People's Republic of China, 2015). my country's rice field wetlands are mainly distributed in the middle and lower reaches of the Yangtze River and the Sanjiang Plain in Northeast my country, followed by Southwest China and South China. There are also a small amount of distribution in the Huanghuaihai region and the Qinghai-Tibet alpine region, and most of them are irrigated rice fields. The middle and lower reaches of the Yangtze River is a famous rice production base in my country. The river and ...
