Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with specific embodiments.

[0017] Table 1 shows the water quality indicators of wastewater discharged from a fructose syrup enterprise:

[0018]

[0019] Treatment process of the present invention is:

[0020] The production and domestic wastewater is discharged to the grid well through the pipeline, and the large particles are removed by the mechanical grid, and then enters the adjustment tank, and then the wastewater is lifted and pumped to the coagulation reaction tank, and large floc alum flowers are formed through the coagulation effect of dosing Then enter the primary sedimentation tank, remove most of the organic matter and SS by gravity sedimentation, and then discharge it into the pre-acidification adjustment tank. A thermometer is set in the pre-acidification adjustment tank to control the water temperature in the pre-acidification tank at 35-38 °C and PH at about 6.5-8.5 . ...

Abstract

The invention discloses a high fructose syrup production wastewater treatment technology. The technology comprises the following steps: 1, production and living wastewater is pretreated, the pretreated wastewater enters an equalizing tank, wastewater discharged from the equalizing tank is sent to a coagulation reaction tank through a wastewater elevator pump and is added with a medicine to realize a coagulation effect in order to remove most organic matters and SS through gravity precipitation, the obtained wastewater is discharged into a pre-acidifying equalizing tank, water discharged from the pre-acidifying equalizing tank is lifted to an EGSB reactor through a water distribution pump for an anaerobic reaction, a material fully contacts with anaerobic granular sludge by adopting the entry of water from the bottom of the EGSB reactor and an internal circulation form, an anaerobic digestive liquid separated through a PP three-phase separator is discharged to an A / O tank, water obtained after aerobic biochemical treatment enters a secondary precipitation tank, and water is discharged from the secondary precipitation tank to the outside in a standard reaching manner; and 2, sludge treatment is carried out. The technology adopting the anoxic and aerobic (A / O) biochemical treatment has the advantages of increase of the sludge interception rate, cancel of an intermediate tank, simplicity and easy control.

Description

technical field [0001] The invention belongs to the wastewater treatment technology in the field of food, in particular to the treatment of high-concentration organic wastewater produced in the fructose syrup production process, and in particular to a fructose syrup production wastewater treatment process. Background technique [0002] High fructose syrup is a starch sugar crystal made by hydrolysis and isomerization of plant starch. It has a unique flavor and is an important sweetener. Because its composition is mainly fructose and glucose; it is called "fructose syrup" and is one of the important food additives in the contemporary food industry. In 2000, fructose syrup gradually rose in China, and the food industry also began to realize some characteristics of fructose syrup and its advantages in food. The volume has soared, showing an unprecedented momentum, ushering in a golden opportunity period in historical development. [0003] However, in the production process, t...
