Abstract
Wood working method of wastewater treatment, it belongs to field of industrial waste water treatment.Comprise the following steps: wood working waste water enters settling tank and precipitates; Through grid and filtering net, remove most suspended substances; Water outlet enters equalizing tank, and equalizing tank, with lime material and acid effect, forms throw out, in formation throw out process and after throw out formed, carries secretly and adsorbing contaminant particle; Water precipitation, filtration is gone out through equalizing tank; Water outlet is pumped into pressure filter by dnockout, removes most minute impurities; Water outlet pumps into biological filter, intakes from bottom to top, and filtrate is useless fibrous nodules; Water outlet pump into water reservoir, direct reuse.The filter cake moisture content be press-filtered out is low, and working cost is low, and treatment capacity is large, and erosion resistance is strong, protection of the environment.Combined multi-stage biochemical processing method, can purify liquid waste thoroughly, and can the wooden reuse by the part in waste water, meets the requirement of environmental protection.
Description
Technical field
The present invention relates to wood working method of wastewater treatment, it belongs to field of industrial waste water treatment.
Background technology
The waste water that wood working is produced is owing to having some biochemical substances, and the composition also more complicated of waste water impurities, therefore common method of wastewater treatment is difficult to this kind of waste water of process.Pool filter sewage is fixed in general employing, but wastewater flow rate handled by this waste water plant is less, and when mud is more, liquid is not easily separated with solid.
Summary of the invention
In view of the defect that prior art exists, the object of patent of the present invention is to provide a kind of combined multi-stage biochemical processing method, can purify liquid waste thoroughly, and can the wooden reuse by the part in waste water, meets the requirement of environmental protection.
For achieving the above object, the technology used in the present invention solution is wood working method of wastewater treatment, it is characterized in that, comprises the following steps:
(1) wood working waste water enters settling tank and precipitates; Through grid and filtering net, remove most suspended substances;
(2) water outlet enters equalizing tank, and equalizing tank, with lime material and acid effect, forms throw out, in formation throw out process and after throw out formed, carries secretly and adsorbing contaminant particle; Water precipitation, filtration is gone out through equalizing tank;
(3) water outlet of step (2) is pumped into pressure filter by dnockout, removes most minute impurities;
(4) water outlet of step (3) is pumped into biological filter, intake from bottom to top, filtrate is useless fibrous nodules;
(5) water outlet of step (4) is pumped into water reservoir, direct reuse.
Described grid inclination angle is 50 degree, and interval of grid strip is 20mm.The filter residue of described pressure filter, through pressurization, is dried, reuse after shaping.Described pressure filter is plate and frame, and dnockout pressure is 0.7 ~ 0.8MPa, and circulate dnockout 5 ~ 6 hours in plate-and-frame filter press, and temperature is room temperature.
After adopting such scheme, compared with prior art have following beneficial effect: the present invention is simple to operate, the filter cake moisture content be press-filtered out is low, and working cost is low, and treatment capacity is large, and erosion resistance is strong, protection of the environment.Combined multi-stage biochemical processing method, can purify liquid waste thoroughly, and can the wooden reuse by the part in waste water, meets the requirement of environmental protection.
Embodiment
Be processed as example with solid wood furniture, method of wastewater treatment of the present invention, comprises the following steps:
Produce a large amount of wood shavings and sawdust after solid wood furniture processing, dry can directly the processing of a part, but still have part to be mixed to form with water to enter waste water, this effluent part is introduced settling tank and precipitates; Through inclination angle be 50 degree, interval of grid strip is grid and the filtering net of 20mm, removes most suspended substances; Water outlet enters equalizing tank, and equalizing tank, with lime material and acid effect, forms throw out, in formation throw out process and after throw out formed, carries secretly and adsorbing contaminant particle; Water precipitation, filtration is gone out through equalizing tank; Water outlet is pumped into plate and frame(type)filter press by dnockout, and dnockout pressure is 0.7 ~ 0.8MPa, and circulate dnockout 5 ~ 6 hours in plate-and-frame filter press, and temperature is room temperature, removes most minute impurities; Water outlet pumps into biological filter, intakes from bottom to top, and filtrate is useless fibrous nodules; Water outlet pumps into water reservoir, direct reuse.The filter residue of pressure filter, through pressurization, is dried, reuse after shaping.
The present invention is simple to operate, and the filter cake moisture content be press-filtered out is low, and working cost is low, and treatment capacity is large, and erosion resistance is strong, protection of the environment.Combined multi-stage treatment process, can purify liquid waste thoroughly, and can the wooden reuse by the part in waste water, meets the requirement of environmental protection.
