Abstract
The utility model discloses an aquatic food processing wastewater treatment system and relates to a wastewater treatment device. The aquatic food processing wastewater treatment system comprises a grid, a regulation tank, a reaction tank, a sedimentation tank, a facultative tank, a contact oxidation tank, a membrane bio-reactor (MBR) tank and a discharge outlet, wherein the grid, the regulation tank, the reaction tank, the sedimentation tank, the facultative tank, the contact oxidation tank, the MBR tank and the discharge outlet are connected in sequence; the regulation tank, the reaction tank and the sedimentation tank are also sequentially and circularly connected with a sludge thickening tank and a pressure filter. By adopting the aquatic food processing wastewater treatment system, the outlet water quality is improved from a three-grade standard to a first-grade standard in the integrated wastewater discharge standard, and about 14 tons of chemical oxygen demand (COD), about 11.5 tons of suspended solids (SS) and about 6.3 tons of ammonia nitrogen are reduced each year.
Description
Technical field
The utility model relates to a kind for the treatment of unit of waste water.
Background technology
Aquatic products processing industry in the coastal region in east China is flourishing, and small-sized aquatic products processing enterprise is numerous.The suspended substance of aquatic food processing waste water and animal grease concentration are high, and ammonia nitrogen and phosphorus are higher, and water temperature is low, and biodegradation rate is slow; Mud is colloidal, large, the difficult dehydration of amount, and easily rot and give out stink, and cause the secondary of phosphorus to discharge and repeat to get back to treatment system, increased intractability and working cost.
Summary of the invention
The utility model aims to provide a kind of wastewater from aquatic product process treatment system of energy effluent quality.
Wastewater from aquatic product process treatment system described in the utility model comprises connected successively grid, equalizing tank, reaction tank, settling tank, oxygen compatibility pool, contact-oxidation pool, MBR pond and discharge outlet, in addition equalizing tank, reaction tank, also and sludge thickener, pressure filter circulates connected settling tank successively.
The utility model is brought up to primary standard by effluent quality from original < < integrated wastewater discharge standard > > grade III Standard, can reduce discharging every year COD approximately 14 t, SS approximately 11.5 t, ammonia nitrogen approximately 6.3 t.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment mono-.
Embodiment
As shown in Figure 1, wastewater from aquatic product process treatment system of the present utility model comprises connected successively grid, equalizing tank, reaction tank, settling tank, oxygen compatibility pool, contact-oxidation pool, MBR pond and discharge outlet, in addition equalizing tank, reaction tank, also and sludge thickener, pressure filter circulates connected settling tank successively.
First wastewater from aquatic product process is processed through grid, removes the larger suspended substances such as fish pomace, strap, to guarantee the steady running of subsequent disposal and the running of lift pump; Water outlet enters equalizing tank to be carried out homogeneous and all measures, and regulates the water quality and quantity of waste water, avoids follow-up biochemical treatment to cause larger load variations.Guarantee that biochemical treatment normally moves; After homogeneous is all measured, pump into flocculation tank, abundant reacted waste water flows into settling tank and carries out mud-water separation, remove most of SS and part COD, ammonia nitrogen, mud is connected to sludge sump, and supernatant liquor sequentially flows into oxygen compatibility pool and contact-oxidation pool, and in oxygen compatibility pool, larger molecular organics is hydrolyzed to the small organic molecule of easy degraded by the oxygen bacterium of holding concurrently, reduce the organic concentration in waste water, and improved biodegradability; The organism that aerobic bacteria in contact-oxidation pool constantly absorbs in waste water is absorbed as nutrition, passes through metabolic reaction.Small molecules and dissolved organic matter are degraded, and a part is oxidized to final product CO
2and H
20, another part is converted into new organism and makes cell proliferation.Waste water enters MBR system subsequently. and due to the high efficiency separation effect of film, separating effect is much better than traditional settling tank, can stablize the effluent quality that obtains high-quality.
Claims (1)
