Embodiment Construction

[0014] A biogas slurry wastewater treatment system, such as figure 1 As shown, it includes a storage unit 10 , a nitrogen removal unit 20 , and a filter unit arranged in sequence. The waste water inlet 21 and the filtrate outlet 22 of the nitrogen removal unit 20 are respectively connected to the outlet 11 of the storage unit 10 and the inlet of the filter unit. When in use, pass the biogas slurry wastewater formed by the livestock and poultry manure in the prior art through a plate-and-frame press filter, anaerobic fermentation and a second plate-and-frame press treatment from the storage unit 10 into the deammonization nitrogen unit 20, Under the action of gravity, the thick slag and the clear liquid are layered, and the pH of the waste water in the deammonization nitrogen unit 20 is adjusted to 9-12, so that calcium and magnesium ions are precipitated, wherein the clear liquid is heated and blown off to separate the ammonia water and the filtrate; part of the ammonia nitroge...

Abstract

The invention relates to the technical field of chemical industry, in particular to a biogas slurry waste water treatment system and a treatment method thereof. The biogas slurry waste water treatmentsystem comprises a material storage unit, an ammonia nitrogen removing unit and a filtering unit which are arranged in sequence, wherein the waste water inlet and the filtrate outlet of the ammonia nitrogen removing unit are connected with the outlet of the material storage unit and the inlet of the filtering unit respectively. The biogas slurry waste water treatment system provided by the invention is simple, stable and reliable, and is low in running cost.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a biogas slurry wastewater treatment system and a treatment method thereof. Background technique [0002] After anaerobic fermentation of livestock and poultry manure, a large amount of biogas slurry wastewater will be produced, containing high concentrations of COD, SS, NH 3 -N, TP, TN, etc., biochemical treatment is difficult. At present, the common treatment method for biogas slurry wastewater is "solid-liquid separation + anaerobic fermentation + SBR method". For large volumes of biogas slurry wastewater, when the SBR method is used for treatment, the investment cost of the biochemical pool is high, the area is large, the method is complicated, the management is difficult, the operating cost is high, and the effect of ammonia removal is not ideal. Contents of the invention [0003] The primary purpose of the present invention is to provide a biogas slurry wastew...
