Abstract
The invention relates to a method for treating piggery wastewater by a sequencing batch biofilm reactor. The method comprises the following processes that: the piggery wastewater is collected by a collection pipe network and then flows into an anaerobic reactor (marsh gas tank); after generating marsh gas, the wastewater flows into the sequencing batch biofilm reactor (SBBR tank); and the SBBR disposal processes and time parameters of each process section are regulated to be proper states by using an automatic control device. Besides, a part of the piggery wastewater can be introduced into the SBBR tank. The treated wastewater meets the requirement of the GB18596-2001 'Discharge Standard of Pollutants for Livestock and Poultry Breeding'.
Description
Technical field
The present invention relates to field of environment engineering technology, relate in particular to the processing of piggery wastewater.
Background technology
Sequencing batch biofilm reactor technology (SBBR) is a kind of ideal intermittent activated sludge treatment process, it have simple to operate, processing efficiency is high, floor space is little, anti impulsion load is strong and have advantage such as denitrogenation dephosphorizing ability, is a biological sewage treatment new technology among dark at present people's research.
But adopt SBBR technology, directly handle the pig farm anaerobic digestion solution as not regulating and control appropriate processing condition, it is low to exist COD and NH4+-N to remove efficient, and carbon-nitrogen ratio is crossed the low denitrification that suppresses, and treat effluent can not satisfy problems such as GB GB18596-2001 requirement.Therefore, how to find out suitable technological process and processing parameter, be the key that the SBBR technology successfully is used to handle the pig farm anaerobic digestion solution, and have not yet to see report by regulation and control.
Summary of the invention
Purpose of the present invention is directly to handle the pig farm anaerobic digestion solution at SBBR technology, COD and NH
4 +It is low that-N removes efficient, and the defective that nutritive element is out of proportion, ammonia-nitrogen content is high provides the operation process process and the processing parameter of the sequencing batch biofilm reactor (SBBR) of handling piggery wastewater.Make the waste water of raising pigs after treatment, reach GB18596-2001 " livestock and poultry breeding industry pollutant emission standard " requirement.
The technical solution used in the present invention is: piggery wastewater enters sequencing batch biofilm reactor (SBBR pond) after handling through sewage collecting pipe network, anaerobic reactor earlier; By the whole process control of automatic control device, the cycle of operation in each stage of online regulation and control SBBR technology, obtain suitable technological process and each process section time parameter to SBBR.Thereby effectively handle piggery wastewater.
Specific embodiment and processing parameter are:
Piggery wastewater is collected and is held back through mechanical grille through the sewage collecting pipe network, removes macrobead pollution substance and floating matter in the sewage, and waste water enters anaerobic reactor (methane-generating pit);
Waste water through efficient anaerobic digestion, after removing most COD acquisition biogas, is regulated water quality and quantity through settling tank in anaerobic reactor, flow into the SBBR pond;
Through the SBBR pond aerobic/the oxygen nitration denitrification of holding concurrently after, further remove the pollutents such as COD, ammonia nitrogen and phosphorus in the waste water, and replenish the former water of a certain proportion of piggery wastewater, ammonia nitrogen removal efficient improved and keep stable;
SBBR is provided with automatic control device, and the cycle of operation in each stage of online regulation and control SBBR technology, concrete parameter is: intake 1 hour, and anaerobism 3 hours, aerobic 7 hours, precipitate 0.5 hour, water outlet 0.5 hour, the time cycle of operation is 12 hours.
The invention has the beneficial effects as follows: the capacity of resisting impact load and the processing power that have improved decontamination apparatus, can realize the combination and the switching of kinds of processes flow process, be convenient to flow process and processing parameter are regulated and control that piggery wastewater reaches the GB18596-2001 requirement after treatment, simple to operate, the processing efficiency height.
Description of drawings
Accompanying drawing is the method for treating piggery wastewater by sequencing batch biofilm reactor process flow sheet.
Embodiment
Piggery wastewater is collected and is held back through mechanical grille through collecting pipe network, enters anaerobic reactor behind the removal macrobead pollutent, removes most COD and enters the SBBR pond afterwards.As handle 150m
3/ d the waste water of raising pigs, the methane-generating pit water outlet flows into the SBBR pond, the SBBR operation condition is: intake 1 hour, anaerobism 3 hours, aerobic 7 hours, precipitate 0.5 hour, draining 0.5 hour, SBBR water outlet COD 300～400mg/L, NH
4 +-N 40～80mg/L TP 5～8mg/L.Process is replenished the former water of a certain proportion of piggery wastewater again, after the steady running, and comprehensive effluent quality COD150～200mg/L, NH
4 +-N 40～60mg/L TP 6～8mg/L.
