Technical field
The utility model relates to a kind of petrifaction sewage treatment unit, relates to a kind of CGSB of utilizing---the petrifaction sewage treatment unit of BAF combined system.
Background technology
Petrochemical complex is one of basic industry of Chinese national economy, also is big, high to the potential threat degree of the ecotope industrial sector of a water consumption, can be rated as " heavy polluter ".Therefore, the comprehensive regulation of petrifaction sewage for the mankind, resource and environment, all has reality and profound significance.In recent years, government and enterprise strict control sewage emissions total amount also improves gradually to the requirement of effluent quality, and part enterprise is in order to realize reusing sewage, the national grade one discharge standard that taken the lead at internal implementation (GB8978-1996).Yet, the biochemical treatment apparatus major part of existing petrochemical industry sewage still adopts traditional plug-flow aeration tank, effect still can during normal the operation, but because petroleum chemical enterprise focuses on the factory effluent in each workshop usually, have characteristics such as complicated component, the feature pollutant kind is many, the water quality and quantity fluctuation is big, biodegradability is relatively poor, therefore, biochemical device is subjected to ballistic situation and happens occasionally, when serious even cause the paralysis fully of biochemical system.Simultaneously, existing biochemical treatment apparatus ubiquity oxygen-supplying amount and the big drawback of dosage are carried out energetically in country under macroscopical background of energy-saving and cost-reducing and pollution emission reduction, and it is imperative that it optimizes improvement.
The utility model content
The purpose of this utility model is in order to solve drawbacks such as poor stability, energy consumption height, floor space that existing biochemical treatment apparatus exists are big in handling petrifaction sewage, provides a kind of CGSB by autonomous research---the petrifaction sewage treatment unit of BAF combined system.
A kind of CGSB of utilizing described in the utility model---the petrifaction sewage treatment unit of BAF combined system is made up of CGSB and BAF, CGSB from bottom to top is divided into the Sludge Bed reaction zone successively, three-phase separation area and plenum zone, the triphase separator lower end places in the three-phase separation area, the upper end is passed three-phase separation area and is connected with water-sealed tank above the plenum zone, water-sealed tank is connected with the collecting methane system by wet test meter, connect three-phase separation area and CGSB bottom by pipe by liquid meter, water inlet pipe passes through impeller pump, liquid meter is connected with the CGSB bottom; Plenum zone is connected with the BAF bottom by water outlet water pipe, the liquid meter of bottom, and BAF is followed successively by water distributor, supporting layer, filter material layer and depositing separation area from bottom to up; Depositing separation area top is provided with overflow weir and baffle plate, and the top is provided with evacuation port, and micropore aeration pipe is located on the supporting layer, and by pipe connecting and gas meter and air communication, CGSB and BAF sidewall are provided with thief hole.
Petrifaction sewage enters the CGSB reactor behind lift pump, under meter from the bottom, upward flow is through anaerobic grain sludge bed reaction zone, and the organism in the water inlet decomposes low molecular organic acids, and can further transform and form methane; The three phase separation of mud, water, gas takes place under the effect of triphase separator afterwards, and sludge settling is to reaction zone, and treating water flows out through overflow weir, water outlet water pipe, and biogas enters plenum zone, recyclable utilization after water seal; Part treating water is back to reactor bottom, and the dilution water inlet also improves upflow velocity.CGSB water outlet gravity flow enters BAF from the bottom, the water distributor of flowing through successively, supporting layer and filter material layer, and under the dual function of filtrate absorption and microbial film degraded, low molecular organic acids, ammonia nitrogen, suspended substance etc. further are removed; Filtrate is in the depositing separation area natural subsidence, or gets back to settlement separate district after meeting baffle plate, and water outlet is flowed out from overflow weir.
The utlity model has following advantage:
(1) employing is at first carried out the efficient anaerobic degraded to sewage based on the CGSB of anaerobic grain sludge and efficient anaerobe reactor, adopt the BAF that integrates biomembrane process and adsorption filtration technology to carry out aerobic treatment afterwards, the processing efficiency height, energy consumption is low, floor space is little, and recyclable biogas;
(2) adopt treating water to reflux and improve the liquid upflow velocity of CGSB inside,, make the granule sludge bed be in swelling state, the muddy water full contact with aerogenesis activity acting in conjunction; The biomass of adding granule sludge is very big, has guaranteed organic quick degraded, thereby CGSB can be moved under higher volumetric loading, short hydraulic detention time condition.If the BAF effluent recycling to CGSB, also can be realized the biological denitrificaion function;
(3) adopt BAF as the subsequent disposal unit, need not to establish again precipitate and separate unit and adsorption filtration unit, greatly saved land resources and initial cost;
(4) heat-insulating property of CGSB and BAF is fabulous, even move under the cold condition about 12 ℃, treatment effect is influenced hardly.
