Embodiment
Embodiment 1:
Systemic contamination is caused in order to overcome sewage sludge secondary circulation in prior art, sludge settling effect is undesirable, and there is self-priming difficulty in various degree in sludge pump, trouble shooting often, the problems such as undercapacity, present embodiments provide a kind of sewage sludge concentration basin as shown in Figure 1, comprise sewage lagoon 1 and sludge sump 2, see-through section 8 is provided with between described sewage lagoon 1 and sludge sump 2, described sludge sump 2 one sidewall upper is provided with multiple valve 5, described valve 5 is connected with sewage lagoon 1 by pipeline, described sewage lagoon 1 overhead surface is provided with sump pump 3, described sludge sump 2 overhead surface is provided with sludge pump 4.
And wherein, sewage lagoon 1 is connected with valve operating chamber with in the middle of sludge sump 2, it is indoor that see-through section 8 and each pipeline between sewage lagoon 1 and sludge sump 2 are all arranged at this valve operation.
The working process of this sewage sludge concentration basin is as follows: first, and each for sewage sludge pipeline is all accessed sludge sump 2, comprises and filtering in backwash water, tank bottom blowdown and other all kinds of sewage sludge unified remittance sludge sump 2, carry out gravity concentration; Secondly, in sludge sump 2 bottom thickened sludge through sludge pump 4 positive delivery to sludge dewatering system, and when observing that in see-through section 8, water quality is relatively limpid, open the valve 5 of the opposite position on sludge sump 2 top, making limpid supernatant liquor gravity flow enter sewage lagoon 1, keeping when observing that water quality is unstable valve 5 to close.
In addition, the length of above-mentioned see-through section 8 is 300mm; Above-mentioned valve 5 is arranged between the 0.5m to 2.0m of underground, and be uniformly distributed between multiple valve 5 simultaneously and arrange or need uneven distribution to arrange according to operation, the setting of multiple different heights valve 5 ensure that the water quality of recirculation water.
Above-mentioned valve 5 is provided with valve handle 6 and valve operation lever 7, valve handle 6 arranges 0.7-1.2m place on the ground by the mode that valve operation lever 7 lengthens, to facilitate on-the-spot operation.The workload of what this mode strengthened alleviate valve opening.
