Embodiment 1

[0018] ①Coarse filtration: use 80 mesh filter to remove large impurities.

[0019] ②Ultrafiltration: Use a 360-mesh filter to remove small impurities, and filter with a filter bag harvested from spirulina.

[0020] ③Continuous microbubble generation technology and bottom aeration: apply microbubble technology and bottom aeration technology in the treatment tank. The micro-bubble generation technology and bottom gas flushing are to lay micro-nano gas flushing pipes at the bottom of the treatment tank. The gas outlet of the gas flushing pipe faces the bottom or near the bottom, which solves the problem of particle deposition blocking the gas outlet and the upward direction of the gas outlet. When the air is blown down, some of the air bubbles collide with the bottom of the pool and become smaller air bubbles. Control the water level at 2 meters.

[0021] ④ The method of dark precipitation, control the water level at 2.5 meters, so that the organic matter can be further precipi...

Embodiment 2

[0025] ①Coarse filtration: use 80 mesh filter to remove large impurities.

[0026] ②Ultrafiltration: Use a 360-mesh filter to remove small impurities. Or use a "T" shaped pipe, the vertical pipe is the water inlet, the upward end of the pipe parallel to the ground is the water outlet, and the other end is provided with a valve, which is beneficial to take out the particles. A rolling brush is connected to the valve. Under the action of hydrodynamic force, the particles close to the filter membrane fall on the other side of the filter membrane, which solves the contradiction between filtration and clogging.

[0027] ③ Continuous microbubble generation technology and bottom aeration: apply microbubble technology and bottom aeration technology in pipelines or treatment tanks. The micro-bubble generation technology and bottom gas flushing are to lay micro-nano gas flushing pipes at the bottom of the treatment tank. The gas outlet of the gas flushing pipe faces the bottom or near ...

Abstract

The invention discloses a method for treating organic matters in spirulina cultivating waste water. The method comprises the following steps of: filtering with a 80-mesh filter screen and a 360-mesh filter screen respectively; continuously applying a micro-bubble generating technology and bottom gas filling, wherein during the micro-bubble generating technology and the bottom gas filling, a gas filling pipe for generating micro-nano bubbles is laid at the bottom of a treatment pond, and the gas outlet hole of the gas filling pipe faces the bottom or approximately the bottom of the treatment pond; controlling the deep water level of the treatment pond at 1.5-2.5 meters, precipitating organic matters and releasing upper purified water; and transferring organic matters precipitated at the bottom of the treatment pond to a filter screen bag, removing moisture by extruding, drying in the sun or drying. Due to the adoption of a mechanical-physical method, the energy consumption is low, no medicine is adopted, water can be used repeatedly, the collected particles have further utilization value, and good economic benefit, high social value and great ecological significance are achieved.

Description

technical field [0001] The invention relates to a method for treating organic matter in spirulina culture wastewater. Background technique [0002] The annual output of spirulina in my country is 15,000 tons of dry Prototheca. In the production of spirulina cultivation, 1 ton of dry spirulina is produced according to 200 cubic meters of culture medium, which is equivalent to the need for 30 million cubic meters of culture medium per year. The vast majority is water, which is generally treated as wastewater. [0003] The waste from culturing spirulina is rich in protein and other nutrients. If it is discharged directly, it will affect the environment, especially increase the eutrophication of the receiving water body. For example, through recycling, the utilization rate of nutrients such as protein can be improved, and it can be used as feed, additives, fertilizers, etc. to increase economic benefits. In addition, the spirulina culture wastewater that removes organic matter,...
