Hydrolytic acidification process method for production wastewater

Abstract

The invention provides a hydrolytic acidification process method for production wastewater, which comprises the following steps: introducing hydrolytic bacteria and acidifying bacteria in a bacteria culture tank into a raw material mixing area, introducing distilled water to control the pH value of the raw material mixing area to 6.6 to 7.8, introducing the production wastewater into a hydrolyticacidification tank at the flow rate of 2-4m <3> / h. The fusion time of the sewage with hydrolytic bacteria and acidifying bacteria is adjusted, and the situation that part of hydrolytic bacteria and acidifying bacteria die due to the fact that the hydrolytic bacteria and the acidifying bacteria do not adapt to the change of the environment when the sewage is fused with the hydrolytic bacteria and the acidifying bacteria is reduced; the raw material mixing area can reach the optimal growth and propagation environment of hydrolytic bacteria and acidifying bacteria, so that the hydrolytic acidification quality and the organic matter conversion efficiency of the hydrolytic bacteria and the acidifying bacteria are improved.

Description

technical field [0001] The invention relates to an acidification process, which belongs to the technical field of wastewater treatment, in particular to a production wastewater hydrolysis acidification process. Background technique [0002] The hydrolytic acidification treatment method is a method between aerobic and anaerobic treatment methods. Combining with other processes can reduce treatment costs and improve treatment efficiency. The hydrolytic acidification process will Anaerobic treatment is controlled in the first and second stages of anaerobic treatment with a short reaction time, that is, under the action of a large number of hydrolytic bacteria and acidifying bacteria, insoluble organic matter is hydrolyzed into soluble organic matter, and macromolecular substances that are difficult to biodegrade are converted into easily The process of biodegrading small molecular substances can improve the biodegradability of wastewater and lay a good foundation for subsequent...

The existing hydrolytic acidification process is not perfect in terms of raw material ratio and process parameter combination, which leads to the current The quality of hydrolytic acidification in some hydrolytic acidification processes, the performance of the efficiency of hydrolytic bacteria and acidification bacteria in transforming organic matter is not ideal
