Abstract
The invention discloses a microbiological method for treating industrial wastewater. The method comprises the following steps: a, microbiological flocculation: industrial wastewater which needs to be treated passes through a water tank containing a microbial flocculant to carry out flocculation of microbes; b, membrane filtration: water treated in the step a passes through a ultrafilter membrane module to be filtered; c, filtration adsorption: water treated in the step b passes through a fluid bed with a biological stuffing; and d, detection: the water treated in the step c is injected into a pure water tank through a pipeline if detected to be qualified, and the water undergoes the above step a according to the detection result if detected to be unqualified. The microbiological method has advantages of simple system structure, stable motion performance and high recovery rate of water. In addition, the method is economical, practical, energy-saving and environmentally-friendly.
Description
Technical field
The invention belongs to the process field of industrial wastewater, be specially a kind of microbial method processing industrial wastewater.
Background technology
Along with deepening continuously of process of industrialization, the existence of the mankind is constituted a threat to by environmental pollution.Particularly industrial wastewater, along with developing rapidly of industry, kind and the quantity of industrial wastewater rapidly increase, and the pollution of water body also increasingly extensively with serious, threatens the health and safety of the mankind gradually.Containing the pollutant produced in the commercial production materials, intermediate product and the product that outflow with water and production process in industrial wastewater, these are all the main causes causing water pollution.Therefore, for protection environment, the water treatment system of exploitation industrial wastewater is particularly important.Water treatment system can reach the water standard that can discharge of national regulation by a series of purified treatment by having the industrial wastewater of pollution or recycle and be again used for commercial production.
Summary of the invention
It is an object of the invention to provide one and do not need reverse osmosis membrane, simple in construction, economy is strong, and energy consumption is low, and the microbial method that the response rate is high processes industrial wastewater.
The technical scheme is that in order to achieve the above object
A kind of microbial method processing industrial wastewater, said method comprising the steps of:
A, microbial flocculation: by required industrial wastewater to be processed through the water tank containing microbial flocculant, carry out the flocculation of microorganism；
B, membrane filtration: a is processed water and filters through ultrafilter membrane group；
C, Filtration Adsorption: b is processed water through having the thermopnore of biologic packing material；
D, detection: if detect qualified, by pipeline inject pure water water tank, if detecting defective, according to testing result enter above-mentioned a step.
Described microbial flocculant is rhodococcus erythropolis fermented product 5-10 part, 2mol/LCaCl2Solution 70-120 part, chitosan 3-10 part.
Described microbial flocculation step temperature controls at 30 DEG C-35 DEG C.
Described ultrafilter membrane is hollow-fibre membrane.
