All parts of the system are connected with each other through a pipeline, so as to form a combined device for the regeneration of papermaking wastewater. The ultra filtration, concentration, water circulation and recycling in the utility model have major characteristic of high water recovery ratio. The utility model has the characteristics of low cost, stable and reliable water quality treatment, wide application scope, convenient operation management and the like.
Description
Technical field
The utility model relates to the resource regeneration integrated assembly, and is especially a kind of to paper waste realization waste water reclamation integrated assembly.
Background technology
In recent years, traditional paper industry Waste Water Treatment generally adopts coagulation, precipitation, process units such as bio-oxidation, water outlet reaches the grade III Standard of country's " integrated wastewater discharge standard " in (GB8978-1996), but facing new energy-saving and emission-reduction, under the environmental protection policy situation of valley harnessing, original effluent quality can not satisfy special emission limit of industrial trade water pollutant and the basin total amount of pollutants discharged control requirement that began to carry out in 2008, there is operation treat effluent water quality inferiority in traditional process equipment, shortcomings such as reclamation rate is low, and effluxing of a large amount of waste water certainly will will be caused environmental pollution.Therefore improve wastewater treatment water quality, improve the cyclic utilization rate of water, reduce the consumption of water resources, realize the resource utilization of trade effluent, be very important.
Summary of the invention
The purpose of this utility model is the problem that solves the paper waste recycle, realizes the paper waste resource utilization.
The purpose of this utility model is achieved by the following technical solution: a kind of paper waste regeneration integrated assembly, comprise water collecting basin, pretreatment system and membrane filtration system, described pretreatment system is made up of high coagulating gas-floating pond, integrated hydrolysis aerobic reactor, second pond, equalizing tank, more medium filter, biologic active carbon filtration device; Described membrane filtration system is made up of ultrafiltration system, security personnel's strainer and reverse osmosis; Pass through pipe connection successively between above-mentioned each equipment.
In water collecting basin, waste water is promoted to pretreatment system by the water collecting basin lift pump then with wastewater collection, and through water turbidity＜0.2NTU that biological treatment, precipitation and filtration at different levels make water outlet, COD＜20mg/L reaches the water inlet requirement of membrane filtration system; Squeeze into membrane filtration system again and carry out ultrafiltration and reverse-osmosis treated, make water outlet can reach the industrial reuse water quality standard.
Further improvement of the utility model is, is provided with intermediate water tank between described pretreatment system and membrane filtration system.Perfect pretreatment technology measure has guaranteed that water outlet reaches membrane filtration system water inlet requirement.
Further improvement of the utility model is, is provided with the dense water of concentrate recirculation pipeline ultrafiltration between described ultrafiltration system and the described equalizing tank and gets back to the equalizing tank cycling and reutilization, has improved the rate of recovery of water, has reduced discharged waste water simultaneously.
