Embodiment Construction

[0019] The technical solutions of the present invention will be further described below in combination with specific embodiments.

[0020] The present invention relates to the improvement of the treatment method for garbage permeate, and proposes a new method for treating garbage permeate. The garbage permeate treated by the method of the present invention can fully comply with the discharge standard, avoiding environmental pollution. destruction. Among them, the garbage permeate before treatment is COD7000→1000O, PH8.5 stock solution, and the effluent water quality of the treated waste liquid is COD, BOD, ammonia nitrogen, and total phosphorus within the third-level discharge, with a pH of about 7.

[0021] Specifically, this embodiment discloses a method for treating garbage permeate, which includes the following steps:

[0022] (1) Add flocculant to the waste permeate to be treated to accumulate and settle the suspended particles in the waste permeate. By adding a floccul...

Abstract

The invention discloses a method for treating garbage penetrating fluid. The method comprises the following steps: (1) adding a flocculating agent into the garbage penetrating fluid to be treated to accumulate and settle suspended particles in the garbage penetrating fluid; (2) stirring the garbage penetrating fluid added with the flocculating agent, and standing for 1-3 hours; (3) conveying the garbage penetrating fluid treated in the step (2) into a filter press for filter pressing so that wastewater in the garbage penetrating fluid seeps out; (4) conveying the wastewater seeped in the step(3) into a sand filter for sand filtration; and (5) conveying the wastewater treated in the step (4) into a DTRO membrane for membrane filtration to obtain a discharge liquid meeting the discharge standard. According to the method, suspended particles in the garbage penetrating fluid are accumulated and settled by adding the flocculating agent so that the purpose of solid-liquid separation is achieved, impurities are further intercepted and the hardness is reduced by matching the press filter, the sand filter and the DTRO membrane, the wastewater meeting the emission standard is obtained, andthe damage to the environment is avoided.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a method for treating garbage permeate. Background technique [0002] Garbage seepage, also known as garbage percolation water, is high-concentration organic wastewater formed due to the compression of garbage during stacking or landfilling and the decomposition of the garbage itself. The water quality is extremely complex and the concentration of pollutants is very high. If the garbage permeate is directly discharged into the external environment, it will cause great harm to the environment. Contents of the invention [0003] The object of the present invention is to provide a method for treating garbage permeate, which can effectively separate solid and liquid from garbage permeate to obtain liquid wastewater, and further remove impurities in wastewater, reduce the hardness of wastewater, and obtain Wastewater that meets the discharge standards avoids damage to the envir...
