Simple floc collection device able to maintain floc integrity

Abstract

Belonging to the technical field of environmental protection, the invention in particular relates to a simple floc collection device able to maintain floc integrity. The device includes a glass tube part, a settlement part and a connecting body, wherein the glass tube part and the settlement part are communicated by the connecting body. An algal fluid and clay or modified clay are added into the glass tube part to form flocs. Seawater is added into the settlement part, and by lowering the liquid level height of the settlement part to lower than the liquid level of the glass tube part, the flocs flow into the settlement part under the effect of pressure difference. By smartly utilizing the principles of a communicating vessel, the device provided in the invention can effectively overcome the situation of easy breaking of flocs during collection, can well keep the morphological characteristics of the flocs, is simple to operate, and is convenient to carry, thus being able to serve as an observation and collection device for flocs in laboratories, factories and field.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a simple floc collection device capable of maintaining the integrity of the flocs. Background technique [0002] Harmful algal blooms, also known as "splashes" in fresh water and "red tides" in seawater, refer to the sudden emergence of planktonic microalgae, protozoa or bacteria in a water body in a short period of time under certain environmental conditions. The catastrophic ecological anomalies that cause serious damage to the ecosystem and changes in water color due to chain multiplication and aggregation. Harmful algal blooms can change the color of seawater; shade the sun, and the growth of organisms below the surface is hindered due to insufficient light, and even die; after death, a large amount of organic matter decomposes, consumes oxygen in the water body, and the lack of oxygen in the water body causes large-scale death of cultured organisms and other...

Problems solved by technology

At present, under the existing means, there are mainly two methods for image acquisition. One method is the real-time observation of flocs during the flocculation process. This in-situ detection method is currently the best flocculation detection method, but it also has disadvantages , such as in the flocculation process, the concentration of particles in the suspension is very high, and the light transmission is very poor, so that this instrument can only detect a small area within the range of the probe, and the in-situ detection technology system is complex. It needs to be connected with a microscope with a CCD, etc., and needs to be installed and debugged (for example, ZL201220067260.7, the application date is a Chinese utility model patent coagulation and floc properties observation and collection device on February 28, 2012), and Not all laboratories in related fields have the conditions or ability to purchase, modify or debug this real-time observation instrument, and this commercial instrument is expensive, which affects the research to a certain extent; another The method is that after the flocs are formed, they are pipetted into a microscope for observation. This method of pipetting is simple in principle and can be realized in various laboratories. However, the flocs are easily broken due to the fast speed when absorbing them.
