Abstract

The invention discloses a reclaimed water treating device and a method for treating reclaimed water by using the same. The water supply in most large and medium-sized cities in China is seriously insufficient; and in order to solve the increasingly-severe water scarcity problem, the sewage recycling work needs to be developed, and the sewage discharged by the cities is used as a water source to be repeatedly used after being treated by using specific equipment. The reclaimed water treating device comprises a regulating tank (1), wherein the regulating tank is connected with an anoxic tank (2) through a sewage lift pump (5); the anoxic tank is connected with an MBR biochemical reaction tank (3); the MBR biochemical reaction tank is connected with a sludge tank; the sludge tank is connected with a clear water disinfection tank (4); and the regulating tank is internally provided with a grid (6). The reclaimed water treating device is used for treating reclaimed water.

Description

Reused water processing device and treatment process thereof
technical field:
the present invention relates to a kind of reused water processing device and treatment process thereof.
background technology:
along with the fast development of Chinese national economy and improving constantly of living standards of the people, Urban Water Demand increases day by day, most big and medium-sized cities service discharge wretched insufficiency of China, for solving increasingly serious water shortage problem, only have and carry out sewage recycling work, the sewage that city is discharged is reused as water resources after particular device process.
summary of the invention:
the object of this invention is to provide a kind of reused water processing device and treatment process thereof.
above-mentioned object is realized by following technical scheme:
a kind of reused water processing device, its composition comprises: equalizing tank, described equalizing tank is connected with anoxic pond by sewage pump, described anoxic pond is connected with MBR biochemical reaction tank, described MBR biochemical reaction tank is connected with sludge sump, described sludge sump is connected with clear water sterilization pool, is provided with grid in described equalizing tank.
described reused water processing device, described anoxic pond side is provided with water-in, and opposite side top is provided with sluice groove and water outlet, and inner filling floater shot filler and anoxic sludge, top is offered manhole and arranged steel step ladder.
described reused water processing device, described MBR biochemical reaction tank side is provided with water-in, and inside is provided with immersed type flat plate membrane component, header supporting on described membrane module and suction pump UNICOM.
described reused water processing device, be provided with sludge lifting pump in described MBR biochemical reaction tank, top has overflow port, and side, bottom begins to rehearse and eats dishes without rice or wine.
a treatment process for described reused water processing device, described method steps is as follows:
effluent stream is mechanical grille or artificial grid through the grid described in grid, grizzly bar gap is 1 ~ 3mm, flow in sewage equalizing tank after skimming oarse-grained suspended substance and impurity, in equalizing tank, carry out water quality, runoff investigation, by sewage pump by sewage lifting to anoxic pond; Give oxygen part by intermittent type, effectively carry out acidifying, nitrated, denitrification, organism is gradated as inorganics and the removal that is degraded, after anoxic pond acidication, enters MBR biochemical reaction tank by water-in; After the active sludge degraded in reaction tank, by antipollution plate film assembly, then enter clear water sterilization pool by suction pump sucking-off, in reaction tank, unnecessary sludge lifting is in sludge digestion tank, and sewage self-flowing is to the outer equalizing tank of case; The water outlet of MBR reaction tank directly can enter reuse pool, adds sterilizing agent or adopts ultraviolet and active ion material to carry out disinfection, after every water-quality guideline is up to standard, discharges or squeeze into middle grid and carry out reuse.
beneficial effect of the present invention:
the present invention by anoxic pond, MBR biological reaction tank, sludge sump, be integrated in a large casing between clean water basin and operation of equipment; compact construction; flow process is succinct; conveniently, level of automation is high, and operating maintenance is easy for floor space little (only having the 1/3-1/2 of traditional technology), increment dilatation; and can move whenever and wherever possible; namely this device directly can be transported to processing target location, direct mass-producing processes, and without the need to carrying out secondary construction.
the present invention collects sewage disposal and water purification process in same device, shallow embedding also can be placed on earth's surface in underground; Process produces, on surrounding environment without impact without mud substantially; Operating performance is good, reliability is high, stable effluent quality, working cost are less.
during Treating Municipal Sewage of the present invention, anti impulsion load, high to contaminant removal efficiency, nitrification ability is strong, nitrated, denitrification can be carried out simultaneously, have the function of denitrogenation dephosphorizing concurrently, very be applicable to Treating Municipal Sewage, decentralized type sewage, water outlet can reuse also can direct qualified discharge, the demand of the different quality of different user can be met.
the filler that novel environment friendly active ion material is made is placed in clear water sterilization pool of the present invention; the heavy metal ion that not only there is sterilization and disinfection effect but also can effectively remove in water outlet; both overcome the heavy metal concentration that secondary pollution problem that medicine wash disinfection causes again reduces water outlet, quality of reused water is improved greatly.
the aerating pipelines in membrane biological reaction pond of the present invention is divided into two-way, and aeration is carried out to periphery active sludge in a road, and aeration is carried out to the diaphragm of membrane module in another road.Its advantage is that the scouring force by producing diaphragm aeration makes diaphragm mutually pat, and can shake off to be attached to the calcification mud on fenestra surface like this, make membrane flux greatly improve the work-ing life extending film, thus reduce running cost.
accompanying drawing illustrates:
accompanying drawing 1 is process flow sheet of the present invention.
