Water treatment is exactly to utilize physics, chemistry and biological method to process waste water, makes purification of waste water, reduces and pollutes, so that reach waste water reclamation, multiplexing, makes full use of water resources.At present, the treatment process steps that materialization sedimentation, separation and biological process are processed is complicated, and the treatment time is long, device structure complexity, and cost is high, and energy consumption is large, energy-conservation not, and floor space is large, and processing efficiency, effect are bad.
Summary of the invention:
Technical problem to be solved by this invention is to provide one-level materialization enhanced coagulation agent and the treatment process thereof of the papermaking wastewater that a kind of technique is simple, cost is low, processing speed is fast.
Technical problem to be solved by this invention adopts following technical scheme to realize:
An one-level materialization enhanced coagulation agent for papermaking wastewater, is grouped into by the one-tenth of following weight:
Ferrous sulfate 40-50kg, aluminium iron polychloride 15-25kg, Xylo-Mucine 5-10kg, sodium polyacrylate 5-10kg, gelatine 5-8kg, polydimethyl hexadiene ammonium chloride 5-8kg, sodium bicarbonate 3-5kg, gac 5-8kg, calcium oxide 3-5kg, iron powder 15-20kg.
The granularity of described iron powder is 100-200 order, and iron level is greater than 90%.
An one-level materialization enhanced coagulation treatment process for papermaking wastewater, comprises the following steps:
(1) first ferrous sulfate, aluminium iron polychloride, Xylo-Mucine, sodium polyacrylate, gelatine, polydimethyl hexadiene ammonium chloride, sodium bicarbonate and calcium oxide solid are joined respectively in 8 medicament barrels of magnetic force usefulness integrated machine for sewage treatment according to above-mentioned weight, then add water and be made into the aqueous solution for the processing of 1000L papermaking wastewater, and each required solution usage of computing 1L papermaking wastewater.
(2) papermaking wastewater injects the dispensing kit of magnetic force usefulness integrated machine for sewage treatment through lift pump, medicament barrel automatic gauge is sequentially added into said components in dispensing kit, add in proportion gac and iron powder, after a series of processing of magnetic force usefulness integrated machine for sewage treatment, obtain clear water simultaneously.
The invention has the beneficial effects as follows: the present invention utilizes multiple materialization reagent, in conjunction with magnetic force usefulness integrated machine for sewage treatment, process papermaking wastewater, processing speed is fast, can efficiently remove suspended substance in sewage, fall turbid, decolouring, limpid water quality, can effectively remove SS, COD, BOD, phosphorus and organism in sewage.
Embodiment:
For technique means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
Embodiment 1:
The one-level materialization enhanced coagulation agent of a kind of papermaking wastewater of the present invention, is grouped into by the one-tenth of following weight: ferrous sulfate 40kg, aluminium iron polychloride 15kg, Xylo-Mucine 5kg, sodium polyacrylate 5kg, gelatine 5kg, polydimethyl hexadiene ammonium chloride 5kg, sodium bicarbonate 3kg, gac 5kg, calcium oxide 3kg, iron powder 15kg.
Embodiment 2:
The one-level materialization enhanced coagulation agent of a kind of papermaking wastewater of the present invention, is grouped into by the one-tenth of following weight: ferrous sulfate 45kg, aluminium iron polychloride 20kg, Xylo-Mucine 8kg, sodium polyacrylate 7kg, gelatine 6kg, polydimethyl hexadiene ammonium chloride 6kg, sodium bicarbonate 4kg, gac 6kg, calcium oxide 4kg, iron powder 18kg.
Embodiment 3:
The one-level materialization enhanced coagulation agent of a kind of papermaking wastewater of the present invention, is grouped into by the one-tenth of following weight: ferrous sulfate 50kg, aluminium iron polychloride 25kg, Xylo-Mucine 10kg, sodium polyacrylate 10kg, gelatine 8kg, polydimethyl hexadiene ammonium chloride 8kg, sodium bicarbonate 5kg, gac 8kg, calcium oxide 5kg, iron powder 20kg.
One-level materialization enhanced coagulation agent in embodiment 1-3 is processed the papermaking wastewater in a certain paper mill, Ma ' anshan City according to following steps:
(1) first ferrous sulfate, aluminium iron polychloride, Xylo-Mucine, sodium polyacrylate, gelatine, polydimethyl hexadiene ammonium chloride, sodium bicarbonate and calcium oxide solid are joined respectively in 8 medicament barrels of magnetic force usefulness integrated machine for sewage treatment according to above-mentioned weight, then add water and be made into the aqueous solution for the processing of 1000L papermaking wastewater, and each required solution usage of computing 1L papermaking wastewater.
(2) papermaking wastewater injects the dispensing kit of magnetic force usefulness integrated machine for sewage treatment through lift pump, medicament barrel automatic gauge is sequentially added into said components in dispensing kit, add in proportion gac and iron powder, after a series of processing of magnetic force usefulness integrated machine for sewage treatment, obtain clear water simultaneously.
Water inlet when embodiment 1-3 implements and the water-quality guideline of water outlet are as shown in table 1:
