Embodiment 1

[0045] The present invention uses microalgae to treat biogas slurry in 2014. In this project, a pig farm in Daying County, Suining City, Sichuan Province, Sichuan Tianhui Energy Technology Co., Ltd. has built a multiphase biogas treatment system for manure. Construction started in early 2015. Among them, manure was used as raw material, multiphase biogas technology was used to produce biogas, and a three-stage aerobic system was used to treat biogas slurry. The project was completed at the end of 2015 and started operation. The operation results show that the multiphase flow biogas system circulates normally, and various technical indicators exceed the traditional biogas digester by more than 30%. However, because the biogas slurry contains a large amount of ammonia, nitrogen, phosphorus and salts, the content of BOD and COD in the biogas slurry is very high, reaching more than 10,000. The biochemical degradation can only reach about 50%, and finally the BOD and COD of the bi...

Abstract

The invention relates to a multilayer microalgae growth and reproduction device, and belongs to the technical field of microalgae reproduction. The multilayer microalgae growth and reproduction device comprises a shell (4), wherein division plates (5), a charging device and a discharging device are arranged in the shell; liquid level limiting devices (3), light sources (8), stirring devices and microalgae growth and reproduction beds (7) are arranged on the upper portion of each layer of the division plates. According to the multilayer microalgae growth and reproduction device, the floor space is small, microalgae growth and reproduction is not affected by the season and the weather, the illumination intensity can be controlled, the exposed area is large, the algae production efficiency is high, and microalgae industrial production can be achieved.

Description

Technical field [0001] The invention relates to the technical field of microalgae growth and reproduction, and in particular to a multilayer microalgae growth and reproduction device. Background technique [0002] With the acceleration of industrialization, greenhouse gas emissions are one of the biggest problems facing mankind. Algae uses solar energy to fix carbon through photosynthesis and convert it into carbohydrates. The algae not only absorb a large amount of carbon dioxide and release oxygen, but also produce organic food, feed, and fertilizer. With the extensive development and utilization of clean energy, biomass energy has developed rapidly. Western countries have carried out large-scale research and small industrial production of oil algae since the 1970s. Therefore, the ecological benefits of algae have received more and more attention. [0003] my country has already started a large area of ​​algae cultivation. But it is also mainly used in the production of high-...
