Be provided with the clorox sterilizing unit between described ultraviolet disinfector and the reuse pool.
Be provided with the coagulating agent adding set between described clean water basin and the filtration unit.
Described clean water basin are by backwash pump while and integral biological filter tank group and filtration unit UNICOM.
Described filtration unit is composed in series by fiber bundle filter and activated charcoal filter.
Described integral biological filter tank group is composed in parallel by two or more integral biological filter tanks; Described integral biological filter tank is composed in series by anoxic biological filter and BAF.
Be provided with lift pump between described storage basin and the equalizing tank.
Be divided into sewage disposal flow process and cleaning process during the work of this device.When carrying out the sewage disposal flow process, effusive plain boiled water waste water is delivered in the equalizing tank from the production unit, and the effective pond of equalizing tank holds 1000m
3, sewage hydraulic retention 5 hours in equalizing tank.The equalizing tank water outlet is promoted in the group of integral biological filter tank by pump then, and integral biological filter tank group is made up of 8 integral biological filter tanks, and effective pond, single integral biological filter tank holds 144m
3Sewage hydraulic retention 6 hours in the group of integral biological filter tank.Sewage is transferred in the clean water basin, the effective pond of clean water basin holds 480m again
3, sewage 2.4 hours laggard line samplings of hydraulic retention in clean water basin detect.Detected result reaches emission standard then can discharge, and discharges not up to standardly then sewage to be delivered to reuse pool.Adding clorox in this process carries out disinfection, filter by fiber bundle filter and activated charcoal filter then, carry out sterilization through ultraviolet disinfector again, arrive reuse pool at last, hydraulic retention can assign production unit to use after 4.5 hours in reuse pool.50 tons/hour of fiber bundle filter single device processing poweies.If 50 tons/hour of activated charcoal filter processing poweies.50 tons/hour of uv steriliser processing poweies;
This device puts into production to be needed to clean after for some time, cleaning process is as follows: at first allow clean water basin fill with water, call retaining in the clean water basin by the backwash water pump, respectively integral biological filter tank group, fiber bundle filter and activated charcoal filter are washed by the backwash water pump, mud in integral biological filter tank group, fiber bundle filter and the activated charcoal filter delivered in the storage basin precipitate, the supernatant liquid of storage basin is sent back in the equalizing tank.Putting aside when the mud in the storage basin just can be with sludge dewatering treatment when a certain amount of.
The utlity model has that plain boiled water wastewater treatment ability is strong, treatment effect good, reclaim the stock quality height and can automatic cleaning equipment in mud, the characteristics that mud can be focused on simultaneously.

Embodiment
Embodiment one: as shown in Figure 1, the primary structure of present embodiment comprises equalizing tank, filtration unit and reuse pool.Described device also comprises integral biological filter tank group, clean water basin, storage basin and uv steriliser; Between described equalizing tank, integral biological filter tank group, clean water basin, filtration unit, ultraviolet disinfector and the reuse pool by lift pump and valve UNICOM successively.More specifically say so at equalizing tank, integral biological filter tank group, clean water basin, filtration unit, ultraviolet disinfector and these devices of reuse pool, all be provided with valve 1 and lift pump 2 between per two devices.Equalizing tank, integral biological filter tank group and filtration unit are respectively by valve 1 and storage basin UNICOM.
As shown in Figure 1, be provided with the clorox sterilizing unit between described ultraviolet disinfector and the reuse pool.Be provided with the coagulating agent adding set between described clean water basin and the filtration unit.
