A kind of device processing mthod of white water from paper making
Technical field
The utility model relates to production wastewater treatment device, particularly a kind of device processing mthod of white water from paper making.
Background technology
At present, the techniques such as the air supporting that the process for the factory effluent of mthod of white water from paper making generally adopts, contact percolation, generally there is floor space greatly, the shortcomings such as the replacing that energy consumption is high, complicated operation, needs frequently carry out filtrate and cleaning in the appliance arrangement of these techniques.
And membrane separation technique emerging at present has the advantages such as filter effect is comparatively strong, convenient, but owing to being subject to the work-ing life of film and the restriction of effluent quality, need to drop into more cost in the research of film, the cost that result also in film is like this very high, in operational process, the shortcoming such as easy blocking, therefore applies difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of device processing mthod of white water from paper making, use water suspension content and be less than 50mg/L, paper pulp colourity reaches production requirement, reach the indices requirement of reuse standard and standard of drainage, with reduced investment, floor space is little, stable effluent quality is up to standard, be convenient to management and operation, can realize the object of Automated condtrol completely.
Formation of the present utility model: a kind of device processing mthod of white water from paper making, by PAC chemicals dosing plant, PAM chemicals dosing plant, equalizing tank, lift pump, PAC line mixer, PAM line mixer, high concentrtion integral water purifier and sludge sump composition, it is characterized in that: equalizing tank is connected with PAC line mixer with former water water inlet pipe by lift pump, PAC chemicals dosing plant is connected with PAC line mixer by PAC chemical feed pipe, PAM chemicals dosing plant is connected with PAM line mixer by PAM chemical feed pipe, PAC line mixer is connected with PAM line mixer by pipeline, PAM line mixer is connected with high concentrtion integral water purifier by high concentrtion integral water purifier water inlet pipe, high concentrtion integral water purifier enters reuse pool by high concentrtion integral water purifier rising pipe, high concentrtion integral water purifier is connected with sludge sump by high concentrtion integral water purifier shore pipe, sludge sump carries out mud by the discharge of sludge sump shore pipe and regularly processes.PH on-line monitoring instrument, turbidimeter are installed in high concentrtion integral water purifier.
Advantage of the present utility model: the first, removal efficiency is high, adding of agent is few; The second, adopt high concentrtion integral water purifier to be separated, operating performance is good; Three, a whole set for the treatment of unit is easy to carry out Automated condtrol, is convenient to Operation, Administration and Maintenance; Four, this plant investment is economized, and working cost is low, and floor space is little.
