Embodiment Construction

[0031] In order to describe the technical content, objectives and effects of the present invention in detail, the following descriptions will be made in conjunction with preferred embodiments.

[0032] A method for quickly evaluating the removal characteristics of various biological fillers for ammonia nitrogen, which includes the following steps:

[0033] Step 1: Connect several bioreactors in parallel: the water inlet of each bioreactor is connected in parallel through the water inlet pipe, and each water inlet pipe is equipped with a water inlet valve, and the water outlet of each bioreactor is connected in parallel through the water outlet pipe. Each outlet pipe is equipped with an outlet valve;

[0034] Step 2: Putting different types of biofillers with the same surface area into bioreactors respectively;

[0035] Step 3: Add activated sludge containing nitrifying bacteria to the bioreactor, keep it for one day, and wash off most of the activated sludge;

[0036] Step 4...

Abstract

The invention discloses a quick evaluation method and a quick evaluation device for ammonia nitrogen removal characteristics of different biological fillings, belonging to the technical field of water treatment and bio-filter performance. The device comprises a bracket, a plurality of bioreactors, a solution collector, a circulating water pump, a waste liquid collector, an air compressor, an aeration head, a peristaltic pump and the different biological fillings. The method comprises the following steps: connecting multiple stages of bioreactors in parallel in a circulating device, arranging the different biological fillings with the same surface area into the bioreactors, carrying out nitrobacteria biofilm formation, measuring the total ammonia nitrogen (TAN) concentration of an inlet and an outlet and the residence time (t) of each reactor, calculating the first-order rate reaction constant k of the different biological fillings on the TAN removal, and determining the characteristics of the different fillings on the TAN removal. According to the quick evaluation method and the quick evaluation device, the TAN removal performances of the different biological fillings can be evaluated at the same time, a test is stable, the cycle is short, the ammonia nitrogen removal kinetic parameters can be efficiently and quickly determined, and the method and the device have remarkable technical and economic meanings for circulating aquaculture.

Description

technical field [0001] The invention relates to the technical fields of aquaculture, water treatment technology and biological filter performance, in particular to a method and device for quickly evaluating the ammonia nitrogen removal characteristics of various biological fillers. Background technique [0002] The traditional flowing water aquaculture model is very dependent on water sources. Once the water source is polluted, the aquaculture will face huge risks. The recirculating aquaculture model establishes sewage treatment facilities so that the aquaculture sewage can be properly treated and returned to the aquaculture pool, reducing the aquaculture process. Relying on the surrounding water environment, reducing sewage discharge during aquaculture, improving survival rate, reducing aquaculture risk, improving yield and quality, and realizing green aquaculture are of great significance to the pond aquaculture industry and sustainable development. [0003] In the high-de...
