Problems solved by technology

[0004] However, in the prior art, the treatment process for pig farm wastewater often lacks simple and effective treatment technology. The use of advanced wastewater treatment technology often costs a lot and the equipment takes up the layout space of the pig farm, which is not suitable for popularization and application; Timely treatment will affect the discharge environment and soil of pig farm wastewater

Embodiment Construction

[0038] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0039] Such as figure 1 As shown, a treatment system for cultivating algae through aerobic sludge particles for pig farm wastewater, the treatment system includes a waste water inlet tank 1, a nitrogen storage tank 2, an air storage tank 3, a waste water drainage tank 4, and a reaction column 5; among them,

[0040] The waste water inlet tank 1 sequentially passes through the water inlet peristaltic pump 1-1, the water inlet time control switch 1-2, and communicates with the inside of the reaction column 5 through the water inlet 5-1 to pass into the pig farm wastewater to the inside of the reaction column 5;

[0041] The nitrogen storage tank 2 passes throu...

Abstract

The invention relates to a system for treating pig farm wastewater by cultivating algae with aerobic sludge particles. The treatment system is characterized by comprising a wastewater inlet tank (1),a nitrogen storage tank (2), an air storage tank (3), a wastewater discharge tank (4) and a reaction column (5). Algae in the reaction column are attached to the surfaces of aerobic sludge particles to make the algae reduce the COD concentration, the phosphate radical concentration and the ammonia nitrogen content of the wastewater in the wastewater treatment process, so the algae are attached tothe surfaces of the aerobic sludge particles, and the loss of the algae is gradually reduced as time goes on, thereby the cultivation amount of the algae is guaranteed, and the loss of the algae in the wastewater is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a treatment system and method for cultivating algae with aerobic sludge particles for pig farm wastewater. Background technique [0002] Algae can synthesize inorganic elements such as nitrogen and phosphorus into their own nutrients through photosynthesis. Under natural light conditions, algae can use CO 2 Or organic carbon is the carbon source, consuming nitrogen and phosphorus in the water to meet the needs of its own growth, while releasing oxygen to increase the concentration of dissolved oxygen in the water. Therefore, the treatment system and method of using algal organisms to treat wastewater has attracted much attention. However, algal organisms are difficult to recover and fix, which largely limits the application of algae biological treatment systems. [0003] Aerobic granules are compact aggregates of microorganisms that can be used for the degradation o...
