Abstract
A sequencing batch biofilm reactor (SBBR) processing system for piggery wastewater comprises an SBBR (SBBR tank), an anaerobic reactor (methane tank) and an automatic control device connected with the SBBR. The flow is as follows: after being connected by a collecting pipe network, the piggery wastewater firstly flows into the anaerobic reactor (methane tank) and the sewage after generating methane flows into the SBBR (SBBR tank); and the automatic control device regulates and controls the process flow and each process section time parameter of the SBBR to the proper states. After being treated, the wastewater achieves the requirement of GB18596-2001 Discharge Standard of Pollutants for Livestock and Poultry Breeding.
Description
Technical field
The utility model relates to field of environment engineering technology, relates 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 furtheing investigate at present.
But adopt SBBR technology, directly do not handle the pig farm anaerobic digestion solution, have COD and NH as not regulating and control appropriate processing condition
4 +It is low that-N removes 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 automatic control regulation and control.
Summary of the invention
The purpose of this utility model 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 piggery wastewater by sequencing batch biofilm reactor (SBBR) treatment system.Make the waste water of raising pigs through after the system handles, reach GB18596-2001 " livestock and poultry breeding industry pollutant emission standard " requirement.
The technical solution adopted in the utility model is: sequencing batch biofilm reactor (SBBR pond) is installed anaerobic reactor before, the automatic control device of sequencing batch biofilm reactor (SBBR pond) by being attached thereto, the cycle of operation in each stage of online regulation and control SBBR technology, obtain suitable technological process and each process section time parameter.Thereby effectively handle piggery wastewater.
Concrete operational process of the present utility model is:
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;
The automatic control device that SBBR is provided with, the cycle of operation in each stage of online regulation and control SBBR technology, concrete parameter is: intake 1 hour, anaerobism 3 hours, aerobic 7 hours, precipitate 0.5 hour, water outlet 0.5 hour, the time cycle of operation is 12 hours.
The beneficial effects of the utility model are: 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, piggery wastewater reaches the GB18596-2001 requirement after treatment, simple to operate, the processing efficiency height.

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.
