Embodiment 1

[0031] as attached figure 1 As shown, the present embodiment provides a bioreactor for aquaculture wastewater bacteria and algae symbiotic pellets, including three parallel reaction boxes 2 placed in the biological pool 1, and two adjacent reaction boxes 2 is placed with an installation box 3, the reaction box 2 is mainly composed of a bracket 21 and a filter screen 22 installed on the bracket 21, and the filter screen 22 divides the inside of the reaction box 2 from top to bottom into two identical The first reaction chamber 201 and the second reaction chamber 202 are used to place cultured and prepared symbiotic pellets of bacteria and algae in the reaction chamber; the reaction box 2 consists of two identical installation frames 211 up and down, two identical vertical plates 212 before and after, Two left and right support plates 213 for connecting the vertical plate 212 are formed.

[0032] as attached image 3 As shown, in this embodiment, each installation frame 211 is...

Embodiment 2

[0042] On the basis of Example 1, this embodiment is provided with a support base 24 installed at the bottom of the biological pool 1 for positioning and fixing the reaction box 2 , and the side of the support base 24 is provided with an aerator with aeration holes 41 . The channel 241 for fixing the air main pipe 4; in order to further strengthen the fixing effect of the first fixing frame 214a on the first filter screen 211 in this embodiment to prevent gaps, several lower heights are formed on the lower bottom surface of the first fixing frame 214a. The cross-section is a sub-arc or semicircular protrusion 214a1.

Abstract

A bacteria-algae symbiotic globule biological reaction device for aquaculture wastewater comprises at least one reaction box body placed in a biological pool, and is characterized in that the reaction box body comprises a bracket and a filter screen which is arranged on the bracket and forms a first reaction chamber and a second reaction chamber with the bracket from top to bottom; and the two sides of each reaction box body are connected with a mounting box in which a first aeration pipe and a light compensation piece are arranged. The reaction device provided by the invention can be directly placed in a biological filter for culture reaction, the device can realize bacteria-algae symbiosis circulation culture, the growth conditions of bacteria-algae balls at different depths can be controlled to be consistent, the wastewater treatment efficiency is high, and the effect is good.

Description

technical field [0001] The invention belongs to the technical field of bacteria and algae ball reaction devices, and in particular relates to a biological reaction device for bacteria and algae symbiotic pellets used in aquaculture wastewater. Background technique [0002] In recent years, my country's aquaculture industry has developed rapidly, with an annual aquaculture output of nearly 50 million tons, which has made great contributions to promoting the development of the national economy and meeting people's demand for aquatic products. However, driven by economic interests for a long time, people often use high input and high discharge methods to achieve high output, and the residual bait, excrement, biological corpses and other wastes in the breeding process have increased a lot, resulting in nitrogen and phosphorus in the water. Pollutants such as pollutants have exceeded the natural purification capacity of the water body, and a large amount of tail water discharged ...
