Description

Runway Pool Photobioreactor

technical field

The utility model relates to the field of aquatic products, in particular to a photobioreactor for a runway pond.

Background technique

Microalgae are widely distributed autotrophic plants with high photosynthetic efficiency. They can synthesize proteins, fats, carbohydrates and a variety of high value-added bioactive substances. They are widely used in the fields of biopharmaceuticals, biomass energy, health products and wastewater treatment. Great application prospects. However, the cost of cultivation is still an important factor limiting its development, and nutrients are one of the main parts of its cultivation cost.

Biogas slurry is the product of aquaculture wastewater after anaerobic fermentation. It is rich in a large number of elements necessary for the growth of microalgae such as nitrogen, phosphorus and potassium, and the anaerobic fermentation process kills a large number of bacteria, etc., which is conducive to the growth of microalgae. It can be used for the cultivation of microalgae. For example, the Chinese invention patent, publication number CN103819053A, Wang Wenguo of the Biogas Science Research Institute of the Ministry of Agriculture, etc. used the struvite precipitation method to pretreat the biogas slurry and then used it for microalgae cultivation. However, the biogas slurry is a brown liquid containing a large amount of suspended solids, and has low light transmittance, which is not conducive to the growth of microalgae. After pretreatment, the light transmittance is still affected.

The existing runway pool photoreactor generally has a water depth of 30-50 cm. Low water depth will increase the light transmittance but reduce the cultivation amount per unit area.

Utility model content

In order to achieve the above object, the technical scheme adopted by the utility model is as follows:

The photobioreactor for a runway pool disclosed by the utility model comprises a runway pool and an agitator arranged on the runway pool, and a supplementary light system is arranged in the runway pool.

Preferably, the supplementary light system includes LED lights arranged on the bottom and/or sides of the runway pool.

Further, the LED light includes a red LED light and a blue LED light. The blue LED light is located on the side of the runway pool, 12 to 20 cm away from the bottom surface of the runway pool. There are plural blue LED lights, and adjacent blue LED lights The interval between them is 25 to 40 cm; the red LED lights are plural, evenly distributed in the central area of the bottom surface of the runway pool, and the interval between adjacent red LED lights is 35 to 45 cm.

Preferably, the runway pool includes a main body pool and a runway baffle, the bottom plate of the main body pool is detachably connected to the runway baffle, and adjacent runway baffles are detachably connected.

Preferably, the runway baffle is a square baffle and/or a U-shaped baffle.

Preferably, the depth of the main body pool is 45 to 55 cm, and the width of the square baffle and the U-shaped baffle are both 40 to 50 cm.

Preferably, the section of the U-shaped baffle is semicircular, and the diameter of the arc is 25 to 40 cm.

Preferably, there are at least two agitators, the agitators are arranged on the straight track of the raceway pool, and one of the agitators is located at the starting position of the raceway pool.

Preferably, all stirrers are driven by the same motor.

The beneficial effects of the utility model are as follows:

1. It is suitable for biogas slurry cultivation of microalgae, has the function of supplementing light, and can increase the cultivation amount per unit area of biogas slurry cultivation of microalgae.

2. The main body pool and the runway baffle, and between the adjacent runway baffles are connected by buckles, which are convenient and fast to assemble and easy to clean.
