Problems solved by technology

[0002] In the process of food processing, there will be a large amount of food organic wastewater containing high fat and high suspended solids. If the wastewater is directly discharged into the river without treatment, it will seriously damage the ecological environment. In order to treat these organic wastewater, the existing methods are expensive and difficult to popularize. use

Embodiment Construction

[0006] The present invention is realized in this way, the method is: the food processing organic waste water that contains high fat, high suspended solids flows into the standing pool through the workshop drainage ditch, and several metal grid filter screens are arranged in the drainage ditch, and the grids are from 4 to 10 The mesh is different to intercept larger suspended solids; the upper and lower oil separators are set in the static tank, and the wastewater is allowed to stand in the static tank for 1-2 days, and the grease suspended solids are basically suspended on the surface, and the surface can reach 1-2 cm thick viscous grease, there is also a small amount of heavy solids deposited at the bottom, and the suspended solids in the middle and upper parts are less, the grease suspended on the surface is blocked by the upper oil separator, and the sediment deposited at the bottom is blocked by the lower oil separator. Regularly use the pump to discharge, and the water out...

Abstract

The invention relates to a method for treating food processing organic wastewater containing high-concentration fat and suspended matters. The method is characterized in that the food processing organic wastewater containing the high-concentration fat and suspended matters flow into a static placing tank through a workshop drainage ditch, a plurality of metal grid filter screens are arranged in the drainage ditch, and grids are 4-mesh to 10-mesh and are not equal to intercept large suspended matters; an upper fat interception plate and a lower fat interception plate are arranged in the static placing tank, the wastewater is statically placed in the static placing tank for 1-2d, the fat which is suspended on the surface is intercepted by the upper fat interception plate, sediments settled at the bottom are intercepted by the lower fat interception plate and the second-grade discharge standard in the national discharge standard GB8978-1996 is satisfied. The method has the technical effects that the wastewater can be continuously treated, the cost is low by adopting a physical treatment method, the method can be easily popularized and used and the pollution is minimized.

Description

technical field [0001] The invention relates to a method for treating organic wastewater, in particular to a method for treating food processing organic wastewater containing high oil and high suspended matter. Background technique [0002] In the process of food processing, there will be a large amount of food organic wastewater containing high fat and high suspended solids. If the wastewater is directly discharged into the river without treatment, it will seriously damage the ecological environment. In order to treat these organic wastewater, the existing methods are expensive and difficult to popularize. use. Contents of the invention [0003] The purpose of the present invention is to provide a method for treating food processing organic wastewater containing high fat and high suspended solids, which adopts physical treatment, reduces secondary pollution, and has low use cost. [0004] The present invention is realized in this way, the method is: the food processing ...
