ABR anaerobic baffle plate reactor for cultivating wastewater treatment

Abstract

The invention discloses an ABR anaerobic baffle plate reactor for cultivating wastewater treatment, wherein the reactor comprises a water inlet bucket, a peristaltic pump, an ABR anaerobic baffle plate reactor and a water outlet bucket which are connected sequentially through water pipes. The ABR anaerobic baffle plate reactor is equipped with five partition plates, the five partition plates are arranged at intervals and divide the ABR anaerobic baffle plate reactor into six compartments having the upper parts connected with each other, and the volumes of the six compartments decrease progressively in turn in the direction of water flow; each compartment is provided with a guide plate, each guide plate divides the corresponding compartment into an upper flow compartment and a lower flow compartment having the bottoms connected with each other, and the volume of the lower flow compartment is one third of that of the upper flow compartment. The device is used for treatment of cultivatingwastewater, has the advantages of stable running, long running time, treatment of cultivating wastewater with high ammonia nitrogen and COD, good treatment effect and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural wastewater treatment, and in particular relates to an ABR anaerobic baffle reaction device used for the treatment of aquaculture wastewater. Background technique [0002] With the rapid development of large-scale pig farms, the impact of a large amount of wastewater produced on the environment has become increasingly prominent. Wastewater has a large amount of discharge and contains high concentrations of COD, TN (mainly NH 4 + -N form) and TP and other characteristics, and often accompanied by the characteristics of pollutants such as disinfectant water, heavy metals, residual veterinary drugs, and various zoonotic pathogens, if not effectively treated, it will affect my country's environment and agricultural ecological production pose a direct threat. However, the pig farming industry is a low-profit industry, and it is impossible to invest a lot of money in wastewater treatment. At prese...

Problems solved by technology

[0005] In recent years, many scholars have carried out research on the treatment of complex wastewater by ABR. There are many types of complex wastewater treated by ABR, including molasses wastewater, baker's yeast production wastewater, printing and dyeing wastewater, pharmaceutical wastewater, sorbic acid wastewater, glyphosate wastewater, tannery wastewater, PTA wastewater, etc., and the removal rate of COD is above 75%, but the removal rate of ammonia nitrogen is not high

However, the concentration of ammonia nitrogen in the breeding wastewater is very high, and the composition is complex. Therefore, there are few reports on the use of ABR to treat pig farm wastewater with complex components, and it is limited to the experimental exploration stage.

The current experimental exploration shows that the factors affecting the anammox in the reactor are complex, such as pH value, organic matter concentration, high concentration of ammonia nitrogen and nitrite nitrogen, and toxic and harmful substances, etc. The law and characteristics of microbial action are not clear, so Leading to poor wastewater treatment effect, unstable operation and other problems
