Abstract
The present invention relates to a multi-stage intestinal wall-type spiral membrane combination---bioreactor process. The process comprises the following operation steps: 1) filtering sewage generated by each step of a production process separately through filter membrane to obtain concentrated liquid; and then extracting to obtain industrial liquid waste for biochemical treatment; 2) collecting the above industrial liquid waste, and performing catalytic wet air oxidation, enhanced biological treatment, coagulation, sedimentation, air flotation, and multi-stage membrane filtration treatment in sequence to enable the liquid waste to meet discharge standards; and 3) collecting sludge impurities generated in above steps for a sludge treatment. According to the present invention, targeted membrane and extraction devices are designed according to specific pollutants in sewage of each step. Industrial liquid waste obtained from sewage of each step after filtration and extraction are collected; and the collected mixed liquor is treated by employing catalytic wet air oxidation technology and enhanced biological treatment, and finally by using multi-stage filtration concentration. The multi-stage filtration concentration is usually performed from coarse to fine, and concentrated extract can be further conducted if possible or required, wherein the extract method is ion-exchange or ionization crystallization extract.
Description
Technical field
The present invention relates to sewage, the process for treating waste liquor in the fields such as a kind of petrochemical complex, mining, metallurgy, electronics, plating, weaving, papermaking, pharmacy, relate in particular to a kind of multistage intestines wall type spiral membrane combination---biological reactor process.
Background technology
Can produce processing wastewater in chemical industry or DYE PRODUCTION process, the concentration of waste water is high, complicated, hardly-biodegradable, if the Waste Water Centralized aftertreatment that each step is produced can be difficult to separate, extract and process because of its complicated.And existing film purification efficiency is not high, the film vulnerable to pollution, and the useful composition that more can not extract wherein carries out recycle.
Summary of the invention
The present invention provides a kind of purification efficiency multistage intestines wall type spiral membrane combination high, respectively filtration, good sewage processing effect in order to overcome the above problems---biological reactor process.
Technical scheme of the present invention is: operate according to following step:
1) sewage that each step production technique is produced obtains concentrated solution behind the membrane filtration respectively after filtration, concentrated solution is extracted obtain industrial effluent, biochemical treatment again;
2) above-mentioned each industrial effluent is gathered, and carry out the catalytic wet atmospheric oxidation successively, after the biological reinforced processing, coagulation, precipitation, air supporting, Using Multistage Membranes filtration treatment, reach emission standard;
3) the mud impurity that produces in the above-mentioned steps gathers and carries out sludge treatment.
Described filtering membrane is in polysulfones composite filtering film, flat sheet membrane, tubular membrane, capillary membranes, hollow-fibre membrane, the porous-film, selects targetedly or optimum combination.
Described hollow-fibre membrane is intestines wall type spiral hollow-fibre membrane.
Described polysulfones composite filtering film is to be doped in polysulfones or the Polyvinylidene by hydrophilic inorganic ceramic fine materials to make composite membrane.
The present invention is designed with targetedly film and extraction element according to the requirement of concrete pollution molecular structure and size, factory's recover materials in each operation sewage.Gather after each operation sewage water filtration and the extraction, mixed solution after gathering carries out catalytic wet atmospheric oxidation technology (CWAO technique) and biological reinforced processing, adopt at last cascade filtration concentrated, cascade filtration is concentrated generally from coarse to fine, also can carry out concentration extraction as may maybe needing, extracting method is that ion-exchange or ionization crystallization are extracted.
