The utility model is provided in view of the above-mentioned problems, having invented a kind of integrated river sewage processing unit, and the device is Based on nano biological circulating water treatment agent+ceramic membrane filter system, floor space is small, operating cost is low, and effluent characteristics are high.
The technical scheme in the invention for solving the above technical problem is:A kind of river based on water treatment agent and ceramic membrane Road sewage-treatment plant, it is characterised in that:Mainly include pretreatment system, medicine system, film filtering system, canyon, it is described pre- Processing system includes grid pond and setting pot, and bulky grain suspension and silt in river are removed respectively;The medicine system tool There are water inlet, dosing mouth and mixing chamber, water inlet is connected with settling pit pipeline;Air accumulator, pneumatics are disposed with the canyon Machine, the film filtering system has setting ceramic membrane in membrane filtration pond, membrane filtration pond, ceramic membrane bottom connection outlet pipe, outlet pipe pipeline Upper setting water pump, membrane filtration bottom of pond portion sets and sets sludge pump on discharge pipeline, discharge pipeline pipeline;Air accumulator is connected by tracheae and mixed Room, mixing chamber connects membrane filtration pond by water pipe, sequentially passes through sewage and water treatment agent after grid pond and settling pit processing and adds To mixing chamber, it is well mixed, is then passed through by pipeline in membrane filtration pond under being sufficiently stirred for of pressure air-dissolving, it is dirty in membrane filtration pond Water is fully handled by water treatment agent, is flowed into while ceramic membrane stops the water after being purified in activated sludge and polluter, ceramic membrane Outlet pipe, discharge or reuse are extracted out after collecting by water pump.
Air accumulator extends gas distribution pipe, and membrane filtration pond bottom of pond sets ceramic aeration tube, and ceramic aeration tube is docked with gas distribution pipe, entered Row fully aeration, can improve the breeding and metabolism of microorganism, gas is inputted by gas distribution pipe.
Ceramic film component needs fixed time cleaning, and gas-adding pipe is provided between the outlet pipe and air accumulator, from gas-adding pipe to going out Input forced air, is recoiled by ceramic membrane bottom up in water pipe, and gas is carried out to membrane from inside to outside after being passed through in film Recoil.
Present apparatus processing river sewage is based primarily upon LS nano biologicals circulating water treatment agent medicine system and film filtering system United application.
(1)Medicine system
LS nano biological circulating water treatment agent is a new green environment protection water treatment agent of company's research and development, and the product is used Pure natural formula non-secondary pollution, is different from the ferro-aluminum type medicament and polymerized organics medicament of in the market, can efficiently remove waste water In all kinds of polluters such as COD, nitrogen phosphorus, heavy metal, and with good adsorption bleaching characteristic.
LS nano biological circulating water treatment agent is added into after medicine system, filled in the presence of pressure air-dissolving with sewage Divide stirring mixing, the nanoporous structure of water treatment agent makes it have huge specific surface area, countless nanometers are formed in water body Level bio-carrier, microorganism breed on carrier and forms bacterium ball, while the zoogloea that water treatment agent is formed have powerful flocculation, Absorption property, surface is enriched to by polluter, polluter is degraded by the metabolism of microorganism.
LS nano biological circulating water treatment agent has the characteristics that and performance:
A. green product non-secondary pollution, reusable edible, energy-saving
B. there is significant Nitrogen/Phosphorus Removal
C. biochemical clearance 20%-30% is lifted
D. bio-carrier is formed, strengthens zoogloea
E. suppress der Pilz, effectively control sludge bulking
F. mud decrement 5%-20% is realized, and sludge dewatering need not add medicament
(2)Film filtering system
Film filtering system organically combines to handle sewage by membrane separation technique with biologic treating technique, in membrane filtration High activity sludge concentration is kept in pond, biological treatment organic loading is improved, so as to reduce sewage treatment facility floor space, and leads to Cross and keep low sludge loading to reduce surplus sludge volume.The activated sludge being immersed in the ceramic membrane interception pond in membrane filtration pond divides with big Sub- organic matter, can extend the growth cycle of microorganism, realize the deep purifying of sewage, and Simultaneous Nitrification bacterium can be fully numerous in system Grow, with significant nitrification effect, realize advanced nitrogen dephosphorization.
The processing unit of film filtering system most critical is the ceramic membrane and ceramic aeration tube being placed in membrane filtration pond.
Traditional membrane filtration is generally adopted by hollow fiber filter membrane, and this technique uses ceramic super-filtering film, aperture 0.001- 0.05 μm, formed by ceramic post sintering.In running, raw water is on the outside of film in membranous system, and purified water is walked on the inside of film, while built-in Air pressure backwash technique, by air-flow, to film, back-pressure is washed from inside to outside, can effectively clean membrane, it is ensured that treatment effeciency.Ceramic membrane Have the characteristics that and performance:
A. all kinds of polluters and bacterial virus are efficiently removed, recycling sewage generated by making can be achieved
B. coordinate micro-pore aeration, MLSS concentration can be improved, improve Microbial denitrogenation dephosphorization efficiency
