Abstract

The invention relates to a device for treating wastewater during production of pentaerythritol. The device comprises a grille groove, a mechanical grille, an oil isolating pool, an adjusting pool, a combined air floater, an aerated micro-electrolysis system, a high-efficiency anaerobic reactor, an improved SBR reaction tank, a water-collecting pool, an anaerobic biological filter, a monitoring pool, a recycling water pool, an acid adding system, an alkali adding system, a polyaluminum chloride (PAC) dosing system, a polyacrylamide (PAM) dosing system, a sludge pool, a sludge pressing filter system, a blast blower and on-lien monitoring instruments such as PH, COD, a liquidometer, a thermometer and the like, wherein the aerated micro-electrolysis system comprises an acid adjusting pool, a micro-electrolysis reaction tank, a neutral coagulation reaction tank, a settling pool and an intermediate water pool; and all the systems are connected with one another sequentially through pipelines. The device treats the wastewater during production of the pentaerythritol by a combined air floatation, aerated micro-electrolysis, biological treatment and aerated biological filter combined method, so that the effluent quality meets the requirement.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a pentaerythritol production waste water treatment device. Background technique [0002] At present, the treatment device for pentaerythritol production wastewater is mainly to set up a regulating tank + hydrolysis acidification tank + SBR. Its disadvantages are as follows: first, the pentaerythritol production wastewater contains oil, and the previous treatment device did not consider the oil removal process, which has a great impact on the subsequent biochemical treatment, and the effluent is difficult to meet the standard stably; second, the pentaerythritol production wastewater contains With high concentration of formaldehyde, the previous treatment device did not consider the process of removing formaldehyde. Under the influence of high concentration of formaldehyde, it is difficult for microorganisms in hydrolytic acidification and SBR to survive and decompose pollutants no...
