[0074] The water outlet system includes a water outlet box 4 and an outlet pipe 12, the outlet pipe 12 is installed on the side wall of the downpipe 5;

[0075] Opti...

Embodiment 2

[0098] Step 1 and step 2 are the same as embodiment 1;

[0099] Step 3. Rapid start-up and operation of the bacteria and algae symbiosis system:

[0100] Step 3.1, water intake: same as Example 1;

[0101]Step 3.2, formation of coupled particle system: Inoculate 1:10 (reactor sewage volume) concentrated algae liquid and broken mycelium (200mg / L final inoculation concentration) at the inoculation port, and add a certain amount of biological flocculant (1:50 (reactor sewage volume)) and photosynthetic bacteria concentrate (1:50 (reactor sewage volume)), start the air compressor at this time, compressed air is supplied into the reactor main body by the aeration head through the air intake pipe, and the reactor main body Driven by the updraft, the sewage in the tank moves upwards in the riser, rises to the connection between the upper end of the riser and the downcomer, enters the downcomer, and then moves down to the bottom of the reactor; the fungal spores gradually form bacter...

Abstract

The invention discloses an immobilized microalgae reactor taking mycelium pellets as the carriers and a wastewater processing method. The reactor comprises a water inlet system, a reactor body, and awater outlet system. The water inlet system comprises a water inlet box. The water inlet box is sequentially connected to a water pump and a water inlet pipe. The reactor body comprises an uprising pipe and a descending pipe. The other end of the water inlet pipe is communicated with the top end of the descending pipe. The uprising pipe is arranged in the cavity of the descending pipe. The bottomof the descending pipe is provided with an aeration head. The aeration head is communicated with an air compressor through an air inlet pipe. The water outlet system comprises a water outlet box and awater outlet pipe. The water outlet pipe is installed on the lateral wall of the descending pipe. The water outlet pipe is communicated with the descending pipe. Water from the water outlet pipe is introduced into the water outlet box. The wastewater processing method comprises following steps: manufacturing a reactor, preparing a condensed alga solution, mycelium pellet suspension, flocculant fermentation broth, and photosynthetic bacteria concentrate, and rapidly starting and running a bacterium-alga commensalism system. The problems that the time for generating a mycelium pellet-microalgaeparticle system is long and the stability of the system is bad are solved.

Description

technical field [0001] The invention belongs to the technical field of waste water biological treatment reuse and resource utilization, and in particular relates to an immobilized microalgae reactor with mycelium balls as a carrier and a waste water treatment method. Background technique [0002] With industrial progress and social development, municipal waste water and water pollution are becoming more and more serious. Modern sewage treatment methods are mainly divided into physical treatment, chemical treatment, physicochemical treatment and biological treatment. In comparison, biological sewage treatment has been established as one of the main means of domestic sewage, urban mixed sewage, and organic industrial sewage treatment for many years due to its wide application range and low investment and operating costs. In biological methods, algae are used to treat wastewater Studies have been reported as early as the 1990s. Microalgae are photoautotrophic single-celled or...
