Description

Technical Field

Nowadays, many laboratories are located indoors, which is a huge consumption and waste in terms of light source energy consumption. The functions of the outdoor laboratories built are general, the equipment is relatively limited, and the indoor and outdoor laboratories are isolated from each other and have no connection, resulting in a waste of resources.

[0004] Second: Traditional laboratories often have the following shortcomings: 1) The experiments that can be conducted in the laboratory are relatively single. For example, a water treatment laboratory can only conduct a single water treatment test; an aquaculture laboratory can only conduct an aquaculture test; an ecological farming laboratory can only conduct related ecological crop experiments, resulting in very low resource utilization, causing a lot of waste and inconvenience; 2) There is sewage discharge in the laboratory: Generally speaking, different experimental designs and experimental drug placement will cause different laboratories to cause a large amount of sewage discharge. On the one hand, these sewages have potential pollution risks to the environment, and on the other hand, the huge water consumption also causes high experimental costs; 3) Lack of results display area: Generally, the management of laboratories is relatively strict, and it is difficult for ordinary people to enter.

[0036] The first test module and the second test module are arranged in an outdoor transparent glass house, which can effectively utilize natural light sources to cultivate crops, and a solar panel is arranged on the top of the transparent glass house to provide power for the entire laboratory.

[0037] The laboratory operation principle of the present invention:

[0038] The first test module of the laboratory of the present invention includes an aquaculture area, a three-dimensional cultivation wall, and a pipeline cultivation area. The conical pool in the aquaculture area is used to carry out breeding experiments of different types of fish. The excrement produced by the fish enters the sewage pipe with the tail water, and is then collected into the water storage tank through the sewage collection pipe and the circulation pump. Different types of aquatic plants are planted on the three-dimensional cultivation wall, the columns and the cultivation pipeline. The tail water collected in the water storage tank is used for natural dripping, and the pollution-resistant crops are screened and cultivated through the hydroponic method. The cultivation wall makes full use of the limited space to carry out fish breeding and crop screening experiments; after installing the frame There is a supplementary light on the top to provide appropriate supplementary lighting for the planting experiment in the module. The corresponding minimum light intensity can be set according to the number and habits of the crops planted. When the light intensity is not enough to support the normal growth needs of the crops, the photosensitive probe can be used to automatically supplement the light. The light source can be divided into different categories such as purple light, red light, yellow light, and blue light to meet different experimental needs. In the pipeline cultivation area, there is a suspension mechanism that can lift the cultivation pipeline. When the crop cultivation experiment is not being carried out, the corresponding cultivation pipeline can be raised, so that the water quality in the conical pool can be observed more intuitively.

[0039] After the tail water in the aquaculture area is absorbed and treated for the first time by the crops in the cultivation pipes and the crops in the three-dimensional cultivation walls, the tail water is collected through the sump and then enters the tail water transfer tank. The tail water is driven by the height difference of the laboratory terrain, that is, the gravitational potential energy of the water, which effectively reduces energy consumption. Four breeding ponds are set on the right side of the second test module. The tail water generated by the first test module and the tail water generated by the breeding pond enter the tail water collection tank together, and then enter the next section, that is, the sedimentation tank in the tail water treatment system. The sedimentation tank includes a filtration and backwashing tank, a sedimentation tank, an anoxic tank, and an anaerobic tank. The tail water is treated at the secondary level by combining physical treatment and chemical treatment. This section can be used for water treatment-related experiments and teaching. After a series of physical and chemical treatments, the tail water enters the oxidation tank, which is equipped with an aeration pipe group to oxygenate the tail water, so that the water body is further purified.

[0040] After passing through the oxidation pond, the tail water enters the ecological purification pond, which is divided into three parts: the emergent plant pond, the floating plant pond and the submerged plant pond. Its setting is based on the different requirements of plant growth for environmental quality. The emergent plants with stronger pollution tolerance are placed in the front, and the submerged plants with weaker pollution tolerance are placed at the end. After being absorbed and treated by plants in different sections, the water quality can meet the growth needs of each component of plants.

[0041] After passing through the ecological purification pool, the tail water has undergone tertiary treatment, its water quality has been fully improved, and the water quality standard has been improved. A high-lift submersible pump is used to divide the treated water into two paths. One path sends the water source to the indoor laboratory through the return pipe for reuse, thereby realizing the recycling of tail water; the other path is discharged into the viewing pool, which is equipped with a viewing glass. Different types of economic fish are raised in the viewing pool; the viewing pool can be divided by spacer plates to achieve the breeding of multiple fish in one pool. At the same time, a fish fry hatchery pool is set on the left side of the second experimental module. The fish fry are hatched and grown in this pool, and can be placed in the viewing pool for breeding later. There is also a Chlorella culture pool next to the fish fry hatchery pool to provide algae cultivation for the entire ecological laboratory circulation system.

[0042] The various units of the entire laboratory of the present invention are closely related to each other and perform their respective functions. The difficult-to-treat tail water is properly treated and utilized, and an organic combination of aquaculture, water treatment, and ecological planting is achieved. This meets the concepts of ecological protection and sustainable development and is conducive to teaching and scientific research demonstrations.
