Method for promoting growth of Habrotrocha sp. using bee honey residue

Abstract

The invention discloses a method for promoting the growth of Habrotrocha sp by using honey residue, which belongs to the technical field of water pollution control. The aim of effectively promoting the growth of the Habrotrocha sp is achieved by adding the honey residue rich in active substances such as flavonoid, terpenes and so on. The method comprises the following steps: the honey residue is added into a Habrotrocha sp culture fluid prepared by CaCO3, a phosphate buffer solution and distilled water, and staphylococcus is taken as food of the Habrotrocha sp to cultivate the Habrotrocha sp in an illumination cultivating box with the temperature of 25 DEG C. The method selects food production waste, namely the honey residue as an additive to promote the growth of the Habrotrocha sp, which has remarkable growth promotion effect on the Habrotrocha sp, can ensure that the population growth rate reaches 0.87d<-1> in an increased logarithmic phase of the Habrotrocha sp, and is far higher than 0.55d<-1> when the honey residue is not added on one hand, can ensure that the honey residue is turned into valuables, realize the cyclic utilization of resources, and also ensure that the method is more economical when practically applied to sewage treatment in the future on the other hand.

Description

technical field

[0001] The invention belongs to the technical field of water pollution control, in particular to a method for promoting the growth of Habrotrocha sp. with biologically active substances. The purpose of effectively promoting the growth of rotifers is achieved by adding honey residue rich in active substances. Background technique

[0002] Rotifer, a small metazoan that lives in clumps on substrates (activated sludge, biofilms) and feeds on suspended particles, contributes greatly to the reduction of suspended solids in sewage treatment systems and the enhancement of perspective, However, its density in sewage treatment plants is not high. Therefore, it is of great significance to try to promote the growth of rotifers and increase their density for sewage treatment.

[0003] Biologically active substances are a type of plant or animal endogenous substances that have specific active functions on biological organisms. At present, biologically active substances ...
