Abstract
The invention discloses a new disposing method of organic waste water based on biochemical disposing and activated charcoal adsorption disposing method, which is characterized by the following: adsorbing waste water through dissolved-air adsorption tower; filling activated charcoal in the tower; decomposing organic pollution through microbe on the carbon due to complete and oversaturated oxygen with abundant organics of waste water CODcr between 400mg/L and 200mg/L in the adsorption tower; making the disposing rate at 98-99%.
Description
Technical field
The invention belongs to the field of handling organic waste water.
Background technology
Handle organic waste water aerobe method commonly used.This method is utilized microorganism decomposing organic pollutant in the presence of oxygen, processing cost is lower, but facility investment height, floor space is big, entering organic matter of water concentration lower (general chemical oxygen demand (COD) chromium method CODcr is controlled at about 400mmg/l) is subjected to very big restriction when handling high concentrated organic wastewater and needing decolouring.Another kind of materialization is handled many methods, and wherein active carbon adsorption is to utilize the activated carbon adsorption organic pollutant to reach the water purification purpose, but activated carbon costs an arm and a leg, and adsorptive capacity is little, after absorption is saturated, and activated carbon regeneration difficulty and cost height.
Summary of the invention
Characteristics of the present invention are that biochemistry and active carbon adsorption are organically combined.Can handle high concentrated organic wastewater, but and the activated carbon life-time service, needn't regenerate, between 400～2000mg/l, organic removal rate 98～99% has decolorizing effect to entering organic matter of water concentration (chemical oxygen demand (COD) chromium method CODcr), and required equipment is simple, reduced investment.For the bigger organic pollutant wastewater of solubleness, because of wherein lacking micelle, be difficult to remove with coacervation, for example NMP (N monomethyl pyrrolidone) waste water uses the coacervation clearance only 4～14%.Other oxygenant method treatment effects are also very low.Adopt this law to handle NMP waste water clearance and can bring up to 98～99%.
The present invention is that waste water enters adsorption tower (2) by air-dissolving apparatus (1) under the pretreated condition of control, and the control flow velocity at ambient temperature, can be removed organic pollutant.Treatment condition are that active carbon column is inoculated through screening and the microorganism water sample of taming earlier, and water sample enters dissolving from top to bottom through removing suspended substance, and pressure is 0.5～2.5kg/cm3, from bottom to top enters adsorption tower again.This law equipment is simple, takes up an area of to lack, and the efficient height, it is wide to be suitable for the influent concentration scope, is a kind of novel method for processing organic wastewater.Being applicable to can be biochemical and solvability organic polluting water preferably, and the load that can withstand shocks.
Claims (3)
1, a kind of method of handling organic waste water, it can be the physico-chemical process of aerobe facture or activated carbon adsorption.Characteristics of the present invention after microbe inoculation gives processing, adopt aerobic biochemical process and sorbent material bonded method, organic removal rate 98～99% at what activated carbon carbon post.
2, a kind of according to the said method of claim (1), organic waste water concentration (chemical oxygen demand (COD) chromium method CODcr) is between 400～2000mg/l, with 0.5～2.5kg/cm
3Pressure by air-dissolving apparatus, enters adsorption tower from top to bottom.
3, a kind of device of handling high concentrated organic wastewater, it can be the device of a kind of aerobe treatment unit or charcoal absorption.Characteristics of the present invention are to use dissolving and the supporting device of activated carbon adsorption tower.
