Abstract
The invention relates to a method for advanced treatment of industrial wastewater by use of a biotechnology and a membrane technology. The method comprises the following steps: a, PH value regulation: putting the industrial wastewater needing to be treated through a water tank containing a base and calcium carbonate; b, membrane filtering: filtering the pretreated water of which the PH value is regulated previously by virtue of an ultrafiltration membrane group; c, microbial flocculation: putting the pretreated water treated previously via the step b through a water tank containing a microbial flocculant, and carrying out microbial flocculation; d, filtration and adsorption: putting the pretreated water treated previously via the step c through a water tank comprising an ultrafiltration membrane group and a resin adsorption group, and carrying out secondary filtration and adsorption to floccules; e, detection: injecting the treated water into a pure water tank via a pipeline if the detection of the treated water is approved, and if the detection of the treated water is unapproved, carrying out one corresponding step again according to the detection result. The method is simple in structure, stable in action performance, high in water recovery rate, economic, practical, energy-saving and environment-friendly.
Description
Technical field
The present invention relates to a kind of recovery method of trade effluent, be specially a kind of method with biotechnology and membrane technique advanced treatment of industrial wastewater.
Background technology
Along with deepening continuously of process of industrialization, environmental pollution constitutes a threat to the mankind's existence.Particularly trade effluent, along with developing rapidly of industry, kind and the quantity of trade effluent rapidly increase, and the pollution of water body also, increasingly extensively with serious, is threatening the mankind's health and safety gradually.In trade effluent, contain the pollutent producing in the industrial production materials, intermediate product and the product that outflow with water and production process, these are all the major causes that causes water pollution.Therefore,, for protection of the environment, the water treatment system of exploitation trade effluent is particularly important.Water treatment system can reach the water quality standard that can discharge of national regulation or recycle again for industrial production by a series of purifying treatment by the trade effluent with pollution.
Summary of the invention
The object of this invention is to provide one and do not need reverse osmosis membrane, simple in structure, economy is strong, and energy consumption is low, the method for the biotechnology that the rate of recovery is high and membrane technique advanced treatment of industrial wastewater.
The technical scheme adopting is in order to achieve the above object:
By a method for biotechnology and membrane technique advanced treatment of industrial wastewater, said method comprising the steps of:
A, regulate pH value: by required trade effluent to be processed by containing the water tank of alkali and calcium carbonate;
B, membrane filtration: the pretreated water that regulated pH value is filtered through ultra-filtration membrane group;
C, microorganism flocculation: the water tank by the pretreated water of processing through b through containing microbial flocculant, carries out the flocculation of microorganism;
D, Filtration Adsorption: the pretreated water of processing through c, through having the water tank of ultra-filtration membrane group and resin absorption group, is carried out to secondary filtration and the absorption to throw out;
E, detection: if detect qualifiedly, inject pure water water tank by pipeline, if detect defectively, enter above-mentioned any road step according to detected result.
Regulate pH value water tank PH to be controlled at 8.0-9.0.
Described microbial flocculant is rhodococcus erythropolis.
Described microorganism flocculation step temperature is controlled at 30 DEG C ~ 35 DEG C.
Described ultra-filtration membrane is hollow-fibre membrane.
The invention has the beneficial effects as follows: system architecture is simple, performance is stable, and the rate of recovery of water is high, and method is economical and practical, energy-conserving and environment-protective.
Brief description of the drawings
Fig. 1 is process flow sheet of the present invention.
Embodiment
By a method for biotechnology and membrane technique advanced treatment of industrial wastewater, it is characterized in that: said method comprising the steps of as shown in Figure 1: a, regulate pH value: by required trade effluent to be processed by containing the water tank of alkali and calcium carbonate; B, membrane filtration: the pretreated water that regulated pH value is filtered through ultra-filtration membrane group; C, microorganism flocculation: the water tank by the pretreated water of processing through b through containing microbial flocculant, carries out the flocculation of microorganism; D, Filtration Adsorption: the pretreated water of processing through c, through having the water tank of ultra-filtration membrane group and resin absorption group, is carried out to secondary filtration and the absorption to throw out; E, detection: if detect qualifiedly, inject pure water water tank by pipeline, if detect defectively, enter above-mentioned any road step according to detected result.
Regulate pH value water tank PH to be controlled at 8.0-9.0, described microbial flocculant is rhodococcus erythropolis, and described microorganism flocculation step temperature is controlled at 30 DEG C ~ 35 DEG C, and described ultra-filtration membrane is hollow-fibre membrane.
Embodiment
Pending trade effluent enters the PH regulating tank that is placed with alkali and calcium carbonate by pipeline, and pending waste water pH value is adjusted to 8, and the PH of described water tank remains on 8.0-9.0; Then trade effluent enters the water tank of ultra-filtration membrane group with pipeline, enter microorganism flocculation water tank by the filtration of ultra-filtration membrane group, to the further impurity elimination of trade effluent, microbial flocculant is rhodococcus erythropolis, and the research experiment of flocculation efficiency and temperature relation shows: under 30 DEG C of conditions, the flocculation efficiency of microorganism can reach 85.2%, by contrast, under 15 DEG C of conditions, but only has 42.1% flocculating effect, so water tank temperature is controlled at 30 DEG C ~ 35 DEG C; Enter Filtration Adsorption through microorganism flocculation treatment trade effluent, by the further filtration of resin absorption and ultra-filtration membrane group; Institute's water quality treatment is detected, if detect qualifiedly, water is recyclable to pure water water tank, if it is defective to detect pH value, again flows back to pH value regulating tank, if it is defective to detect particle, again flows back to Filtration Adsorption water tank; Circulation can reach 100% the recovery to water like this, can play the recycling to water, energy-conserving and environment-protective.
