Embodiment
[0024] Embodiment: a kind of invention fruit juice wastewater treatment process, as figure 1 shown, including the following steps:
[0025] 1. Juice wastewater enters the grid pool first, and there are two thick and thin grids in the grid pool to remove larger fruit particles and pomace in the wastewater.
[0026] 2. The effluent from the grille tank enters the grit settling adjustment tank, which has the function of grit settling. The main details are: the front section of the grit settling adjustment tank is corridor type, which can reduce the flow rate and make the inorganic particles in the wastewater such as sand free. Settling, so as to play the role of sand, the rear section of the pool is equipped with a perforated aeration pipeline, so that the wastewater is evenly mixed. Due to the production characteristics of fruit juice wastewater, the water quality will fluctuate significantly, so the residence time of the regulating tank must be more than 24 hours.

The invention discloses a fruit juice wastewater treating process. Fruit juice wastewater is discharged after reaching the standard through thick and thin bar screening, sand setting and regulation, filter pressing, anaerobic treatment, aerobiotic treatment and coagulating sedimentation in sequence, filter press sludge and secondary sedimentation tank sludge are subjected to filter pressing through a sludge filter press after entering a sludge thickener to be concentrated, and sludge cakes are transported outwards. The treatment efficiency of the fruit juice wastewater treating process is high, discharged water can meet the standard stably, civil engineering cost is saved, land is saved, the process is simple, the dosage of a system is reduced, sludge can be directly taken as fertilizer after simple concentration, and secondary pollution is avoided.
Description
technical field [0001] The invention belongs to the technical field of wastewater treatment of environmental engineering, and in particular relates to a fruit juice wastewater treatment process. Background technique [0002] Juice is made of high-quality fresh fruit as raw material, which is processed and prepared by selecting, washing and squeezing. Juice produces a large amount of high-concentration organic wastewater during the production process. Wastewater mainly comes from fruit washing, crushing, juicing and container cleaning. Wastewater mainly contains a large amount of pomace, sugars and organic acids. Generally, the COD is around 10,000mg / L. [0003] The traditional treatment process is mainly as figure 1 As shown, the traditional treatment process has the following disadvantages: ①The process is long; ②The system has a large amount of dosing; ③It occupies a large area and the cost of civil construction is high; ④The treatment effect is unstable; ⑤The sludge can...
