Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. The following description with reference to the accompanying drawings is provided to assist in understanding the embodiments of the invention defined by the claims. It includes various specific details to assist understanding, but they are to be construed as merely illustrative. Accordingly, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Also, in order to make the description clearer and simpler, a detailed description of functions and configurations well known in the art will be omitted. As used in the description, the terms "front," "back," "left," "right," "up," and "down" refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

The invention will be further described with reference to the following several drawings: referring to fig. 1, the device for zero discharge of landfill leachate and landfill leachate membrane concentrate and water recovery comprises a pressure filter tank 1, a flocculation tank 2, a pickling tank 3, a PH adjusting tank 4 and a reverse osmosis filter tank 5, wherein the pressure filter tank 1 comprises a tank body 12 and a pressure filter plate 11 matched with the tank body in size; the effluent of the pressure filter 1 is pumped into the upper part of a flocculation tank 2 through a water pump, the flocculation tank 2 comprises a flocculant pouring opening 21 at the top and a filtering screen 23 at the middle section, the effluent at the bottom of the flocculation tank 2 is pumped into a pickling tank 3 through the water pump, and the top of the pickling tank 3 is provided with a sulfuric acid pouring opening 31; the pickling tank 3 is through pipeline and liquid pump with a water pump income PH equalizing basin 4, PH equalizing basin 4 communicates with each other with reverse osmosis filter tank 5 through force (forcing) pump and pipeline, reverse osmosis filter tank 5 includes reverse osmosis membrane 51 and goes out tap 52.

In the garbage leachate and garbage leachate membrane concentrated solution zero-discharge and water recovery device, garbage is placed in the pressure filter 1, the pressure filter plate 11 is pressed downwards under force, and permeate membrane filtrate in the garbage is extruded out and is extruded into the flocculation tank 2 through a pipeline. The baffle 22 in the flocculation tank 2 is closed and the operator pours a flocculant, in this example polyaluminium salt or a composite flocculant based on polyaluminium salt, through a flocculant pouring spout 21. Under the action of the flocculating agent, a large amount of organic matters which are biologically toxic and difficult to decompose originally remained in the filtrate are floccules. At this point the operator pulls away the baffle 22, the floe is left on one side of the filter screen, and the filtrate enters the bottom of the flocculation tank 2 and is pumped into the pickling tank 3 by the water pump. In the pickling tank 3, sulfuric acid is poured through a sulfuric acid pouring opening 31 to generate ammonium sulfate, effluent containing the ammonium sulfate is sent into a pH adjusting tank 4 through a water pump, slaked lime is added into the pH adjusting tank 4, the pH value of the effluent is adjusted to be alkalescent and is pumped into a reverse osmosis filtering tank 5 through a pressure pump, under the pressure action of the pressure pump, pure water molecules flow out through a reverse osmosis membrane 51, and concentrated solution with high concentration enters an incinerator 6 to be dried. The concentrated solution and the flocculate in the flocculation tank are both sent into an incinerator 6 for drying or incineration treatment.
