Problems solved by technology

[0002] Most of the sewage collected by industrial sewage treatment plants is industrial wastewater, and the biodegradability of sewage is poor. Only conventional biochemical treatment is used, and it is difficult to treat it up to the standard. Therefore, it is necessary to add an anaerobic hydrolysis unit to improve the biochemical property of sewage in the process flow.

Abstract

The invention discloses sewage hydrolytic acidification treatment equipment. The equipment comprises a pre-reaction tank, a hydrolytic acidification reaction tank, a water inlet pipe and a water outlet pipe, a connecting pipe is arranged between the pre-reaction tank and the hydrolytic acidification reaction tank, and a plurality of water distribution pipes A and a plurality of sludge discharge pipes A are arranged in the pre-reaction tank; a plurality of water distribution pipes B and a plurality of sludge discharge pipes B are arranged in the hydrolytic acidification reaction tank, the sludge discharge pipes A are arranged below the water distribution pipes A, the sludge discharge pipes B are arranged below the water distribution pipes B, the water distribution pipes B are connected with the connecting pipe, the sludge discharge pipes A penetrate through the pre-reaction tank and are connected with the sludge discharge pipes B, and the water inlet pipe penetrates through the pre-reaction tank and is connected with the water distribution pipes A; and the water outlet pipe is connected with the hydrolytic acidification reaction tank. The invention further discloses a hydrolytic acidification treatment method for the sewage treatment plant. Raw sewage enters the pre-reaction tank to be adjusted and buffered, the maximum efficiency of the follow-up hydrolytic acidification reaction is guaranteed, sludge separated from the hydrolytic acidification tank is collected through the sludge discharge pipe A and the sludge discharge pipe B, and the efficiency of the hydrolytic acidification reaction is improved.

Description

technical field [0001] The invention relates to sewage hydrolysis acidification treatment equipment and a treatment method thereof, belonging to the technical field of sewage treatment. Background technique [0002] Most of the sewage collected by industrial sewage treatment plants is industrial wastewater, and the biochemical properties of sewage are poor. It is difficult to meet the standard with only conventional biochemical treatment. Therefore, it is necessary to add an anaerobic hydrolysis unit to improve the biochemical properties of sewage in the process flow. [0003] The hydrolytic acidification treatment method is the early stage of anaerobic treatment. According to the different growth conditions of methanogenic bacteria and hydrolytic acid-producing bacteria, the anaerobic treatment is controlled under the condition of containing a large number of hydrolytic bacteria and acidifying bacteria, and the insoluble organic matter in water is hydrolyzed into soluble or...
