Step 2: the spoil disposal water in sedimentation basin and the precipitated liquid of backwash draining enter spoil disposal pond by pipeline, spoil disposal pond is mixed into homogeneous spoil disposal water to spoil disposal water and precipitated liquid, homogeneous spoil disposal water pumps into concentration basin by pipeline, and the precipitating sludge of spoil disposal basin bottom pumps into storage basin by active redundancy pipeline;
Step 3: homogeneous spoil disposal water carries out standing gravity concentration precipitation in concentration basin, the supernatant qualified discharge of homogeneous spoil disposal water, the homogeneous spoil disposal water thickened sludge bottom concentration basin enters storage basin by pipeline;
Step 4: storage basin carries out mixing and stores after receiving precipitating sludge and thickened sludge, precipitating sludge and thickened sludge are pumped into folded spiral shell formula dewaterer by pipeline by storage basin as required;
Step 5: folded spiral shell formula dewaterer carries out processed to precipitating sludge and thickened sludge, and the mud cake formed after dehydration is transported by sanitationman, and the filtrate formed after dehydration is recycled to spoil disposal pool circulating by pipeline.
As preferably, the quantity in described spoil disposal pond has one, and the quantity of described backwash draining recovery pond has two, when overhauling in spoil disposal pond, a backwash draining recovery pond can be used to use as spoil disposal pond temporarily.
As preferably, the quantity of described concentration basin has one, when concentration basin overhauls, can directly enter precipitating sludge to storage basin by spoil disposal pond, and folded spiral shell formula dewaterer runs under low solid content.
As preferably, the quantity of described storage basin has one, and when storage basin overhauls, concentration basin can reduce the mud reserves of concentration basin in advance, stores up mud, the maximum three day time of storage mud amount when overhauling in order to subsequent technique.
As preferably, the quantity of described folded spiral shell formula dewaterer has one, and folded spiral shell formula dewaterer is bitubular form, and described folded spiral shell formula dewaterer can run by monotubular, for subsequent use each other between the bitubular.
Beneficial effect of the present invention: the present invention adopts folded spiral shell formula dewaterer, folded spiral shell formula dewaterer the earliest Shi An NIKON brought China in 2007.Operation principle is, folded spiral shell body is mutually stacked by retainer ring and travelling ring, and helical axis runs through wherein, formation tubular filtration.Helical axis is while conveying mud, promote travelling ring to move in a circle, there is automated cleaning filter joint function, prevent blocking, thus ensure the operation that dewaterer is continual and steady, normally produce, spoil disposal water is after gravity concentration, solid content brings up to about 2.0% from 0.2%, and thickened sludge dewaters by entering folded spiral shell formula dewaterer through storage basin, special circumstances, the spoil disposal water of solid content 0.2% directly enters the dehydration of folded spiral shell formula dewaterer, present device body has feature for subsequent use, therefore the complete machine spare condition as other dehydrated form is eliminated, entering muddy water solid content can be low to 0.2%, thickened sludge can be entered and can enter again uniform spoil disposal water, process thickened sludge under normal circumstances, in particular cases directly process spoil disposal water, two circuits can be realized for subsequent use each other with this, only need construction concentration basin, be designed with concentration basin, main consideration is safety and stability aspect, by concentrated, the mud entering dewaterer is comparatively stable, dehydration PAM demand is stablized, be conducive to equipment automatically to run, realize unmanned.The present invention has stable equipment operation, and operating maintenance is convenient; Site environment is good, clean, noise is low; Equipment investment is few, the advantage that operating cost is relatively low.
