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 device and a method for quickly evaluating the ammonia nitrogen removal characteristics of various biological fillers, and belongs to the technical fields of water treatment technology and biological filter performance. The device includes brackets, several bioreactors, solution collectors, circulating water pumps, waste liquid collectors, air compressors, aeration heads, peristaltic pumps and different types of biological fillers. Different types of biological fillers with the same surface area are placed in the bioreactor in the multi-stage parallel circulation device, and the nitrifying bacteria are filmed, and the total ammonia nitrogen (TAN) concentration and residence time (t) at the inlet and outlet of each reactor are measured, and calculated. The first-order rate reaction constant k of TAN removal by different biological fillers determines the characteristics of different fillers for TAN removal. The invention realizes the evaluation of the total ammonia nitrogen removal performance of different biological fillers at the same time, and the test is stable, the cycle is short, and the kinetic parameters of the ammonia nitrogen removal can be determined efficiently and quickly, which has obvious technical and economic significance 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...
