Background
In recent years, the rapid development of the livestock industry makes the culture pollution become a main source of agricultural pollution, and the treatment of the sewage of the livestock farm becomes a main factor for the healthy and sustainable development of the livestock and poultry industry. Research shows that the livestock and poultry breeding scale in China is continuously increased, the total breeding amount is increased by 8% per year, and the harm to the environment is increased more and more. The treatment process of the aquaculture wastewater mainly comprises the following steps: water inlet → primary sedimentation → homogenization → hydrolytic acidification tank → anaerobic fermentation → mixed sedimentation → water outlet.
The hydrolysis treatment method is a method between the aerobic treatment method and the anaerobic treatment method, and can reduce the treatment cost and improve the treatment efficiency by combining other processes. Hydrolysis refers to the biochemical reaction that occurs extracellularly before the organic material enters the microbial cells. The purpose of hydrolytic acidification in a hybrid anaerobic digestion process is to provide a substrate for methane fermentation in a hybrid anaerobic digestion process. In the hydrolysis acidification tank in the prior art, a sludge bed area and a clear water layer area are divided, sewage to be treated and residual microbial films dropped off during backwashing of a filter tank enter the tank from the bottom of a reactor, and are quickly and uniformly mixed with a sludge bed through a water distributor with a reflecting plate. The main problems in the prior art are that: in order to keep the high treatment efficiency, enough activated sludge in the tank must be kept, and simultaneously, the entering wastewater is mixed with the activated sludge as fast as possible, so that the contact time and the contact area of the activated sludge and the water inlet organic matters are increased, but the filler layer of the sludge area per se is impacted by water flow to cause the fluctuation of the filler of the sludge, the sludge is ineffectively dropped from the filler, and the hydrolysis effect of the sludge area is deteriorated. In the prior art, the water distribution pipe is arranged at the bottom of the pool and is provided with a plurality of groove-shaped structures, so that water distribution is facilitated, but the cost of the water distribution pipe at the bottom of the pool is high on the one hand.
