The sludge discharging device is characterized by comprising a self-sucking pump and an underwater sludge absorber, wherein the self-sucking pump is connected with the underwater sludge absorber through a slurry guide pipe; a check valve is mounted at the upper end of the underwater sludge absorber, universal wheels are mounted at the lower end of the underwater sludge absorber, and at least one slurry suction inlet is formed in the underwater sludge absorber. Compared with the prior art, the sludge discharging device has the beneficial effects that by virtue of continuous movement of the underwater sludge absorber and continuous pumping of the self-sucking pump, increasing settled sludge at the lower part of the settling tank for Biolak sewage treatment can be thoroughly eliminated, so that a float sludge phenomenon in the settling tank is effectively restrained, and the standard emission of effluent is guaranteed; the trolley-type self-sucking pump is convenient to move and is adapted to various terrains; the four universal wheels are mounted at the lower end of the underwater sludge absorber, so that the direct contact between sharp objects and an HDPE anti-seepage membrane is prevented, and the damage of the HDPE anti-seepage membrane can be effectively avoided.
Description
Technical field
The invention belongs to equipment for sewage treatment technology, particularly relate to the mud discharging device of depositing reservoir in a kind of Biolak sewage treatment process.
Background technology
Biolak sewage treatment process (BIOLAK) technology studies successful a kind of Novel sewage treatment technology by German Feng Nuodunxi company in nineteen seventies, and formally to have put into operation first BIOLAK process sewage treatment plant in nineteen eighty-three.Its unique distinction is to adopt underload activated sludge process, produces a kind of awave mixed oxidization effect, thus create the good growing environment of all kinds of extraordinary microorganism by a kind of floating aerating chain, realizes higher denitrogenating phosphorus effect.Common BIOLAK process flow process: dephosphorization pond-aeration tank (multistage A/O function)-sedimentation basin-depositing reservoir-standard discharge.Wherein, dephosphorization pond: sewage enters this pond together with returned sludge, fully mixes, then enters aeration zone under agitator effect.Sewage, in this district's generating portion hydrolysis acidification reaction, improves the biodegradability of sewage, alleviates the burden of follow-up aeration zone, thus reduce the volume of power consumption and aeration zone.The extended aeration of mixed zone and aerobic treatment region matches, and can play good effect to the denitrogenation dephosphorizing of sewage; Aeration tank: aerator is that micropore sleeve pipe swings aeration form, and aerator is drawn by float tube, is suspended in pond, is connected between aerator with gas distribution pipe with flexible pipe.During ventilation, aerator produces motion due to unbalance stress in water.Due to the operation of aeration head, rising bubble forms air supporting, and movement locus increases the dead time that gas ducks in drink, and therefore improves coefficient of oxygen utilization.Sedimentation basin: sewage is Separation of Solid and Liquid in clarification sedimentation basin, be deposited in the mud of bottom by floated mud-sucking device sucking-off, a mud part is back to aeration tank, and a part is beaten to homogeneous pond by residual sludge pump, dehydration; Depositing reservoir: depositing reservoir upper end size: 14.8m × 72.08m; Lower end size: 8.2m × 56.5m; Chi Shen: 5m depositing reservoir three is 33.3 ° of slope angles, and one side is concrete face wall, and slope and bottom are all covered with HDPE antiseepage film, and antiseepage film can not contact with sharppointed article, easily damaged, then underground water can be made to rise in depositing reservoir.Biolak sewage treatment process can not empty depositing reservoir, in case bottom HDPE antiseepage film is excessive and floating by groundwater pressure simultaneously.Germany's technique has particular/special requirement to water outlet DO, and DO must be greater than 3mg/L and could arrange outward, and namely depositing reservoir uses as an oxygen supply pond.But Environmental Protection in China department is to water outlet DO not requirement, but have requirement to water outlet SS, when domestic Effluent criteria is primary standard, for strengthening water quality further, often using depositing reservoir as sedimentation basin.Because depositing reservoir does not have mud discharging system, cause heavy mud below depositing reservoir cumulative, form large stretch of mud scum after anaerobism, have a strong impact on again water outlet indices.
Biolak sewage treatment process depositing reservoir spoil disposal problem is sewage treatment plant's technical barrier urgently to be resolved hurrily.
