Abstract
The invention relates to a propylene epoxide sludge sewage treatment device. The propylene epoxide sludge sewage treatment device comprises a pump room and a homogenizing sedimentation tank connected with the pump room, wherein the homogenizing sedimentation tank is connected with a sludge thickening tank, the propylene epoxide sludge sewage treatment device also comprises a primary sedimentation tank connected with the homogenizing sedimentation tank by virtue of an aeration tank as well as an intermediate water collecting tank, a second-stage contact oxidation tank, a secondary sedimentation tank, a congulation reaction device and a contact filtration device which are sequentially connected with the primary sedimentation tank, the secondary sedimentation tank and the contact filtration device are also connected with the sludge thickening tank, and the sludge thickening tank is also connected with a pressure filter. The propylene epoxide sludge sewage treatment device has the beneficial effects that firstly sewage treatment efficiency is high, secondly load impact resistance is high and adaptive capacity on fluctuation of water quality, thirdly energy consumption is low and operation is easy, fourthly target rate is high.
Description
Technical field
The present invention relates to a kind of Novel sewage treatment process, say more specifically a kind of sewage treatment process of processing high temperature and high salt part strong basicity epoxy propane waste water.
Background technology
Due to high in salt, the high temperature of epoxy propane waste water, high pH, after the Ca (OH) 2 that epoxy propane waste water dissolves simultaneously and other waste water mix also by producing new precipitation, so the processing of epoxy propane waste water is very difficult.Sewage farm is in conjunction with self design conditions, on the basis of traditional treatment process, each characteristic for epoxy propane waste water is optimized respectively transformation, explore a kind of sewage treatment process of processing high temperature and high salt part strong basicity epoxy propane waste water, this technique efficiently solves microorganism non-refractory, the features such as sensitivity fluctuate to pH, after processing, sewage compliance rate is high, process convenient operation and control.
Summary of the invention
The object of the invention is to overcome the deficiency of traditional biochemical sludge sewage treatment process, provide a kind of processing efficiency high, strong shock resistance, energy consumption is little, the simple sewage sludge treatment device of operation.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of propylene oxide sewage sludge treatment device, comprise pump house and connected precipitation from homogeneous solution pond, described precipitation from homogeneous solution pond connects sludge thickener, it is characterized in that: also comprise the one-level settling tank being connected with precipitation from homogeneous solution pond by aeration tank, also comprise middle water collecting basin that one-level settling tank connects successively, two sections of contact-oxidation pools, second-level settling pond, coagulation reaction device, contact percolation device, described second-level settling pond is also connected with sludge thickener with contact percolation device.
Above-described sludge thickener also connects pressure filter.
The invention has the beneficial effects as follows:
1. sewage treating efficiency is high;
2. anti-load impact ability is strong, adaptable to water variation water quality;
3. energy consumption is little, and operation is simple;
4. compliance rate is high.
Brief description of the drawings
Fig. 1 is waste disposal plant process flow sheet of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
From accompanying drawing 1, the present invention includes pump house and connected precipitation from homogeneous solution pond, described precipitation from homogeneous solution pond connects sludge thickener, also comprise the one-level settling tank being connected with precipitation from homogeneous solution pond by aeration tank, also comprise middle water collecting basin that one-level settling tank connects successively, two sections of contact-oxidation pools, second-level settling pond, coagulation reaction device, contact percolation device, described second-level settling pond is also connected with sludge thickener with contact percolation device, and described sludge thickener also connects pressure filter.
First pass through open channel sewage and the epoxy propane waste water of grid by rational proportion, and add a certain amount of hydrochloric acid, guarantee to make to meet through pretreated sewage quality the condition that enters aeration tank.Sludge concentration is controlled at higher level by aeration tank, increase its impact resistance and improve processing power and efficiency, the internal reflux link increasing can make activity sludge reflux that aeration tank tail end concentration is higher to aeration tank front end, effectively takes precautions against the impact that the fluctuation of influent quality brings.After one section of processing, sewage enters two sections of contact-oxidation pools, by Dissolved Oxygen concentration Control in pond at high level, microorganism on filler is fully reacted, organism in degrading waste water, finally at water exit end, administration system is set, further reduces suspended substance and ammonia nitrogen by adding polymerize aluminum chloride and clorox.Through two sections of sewage after treatment, enter fibre turntable filter chamber and carry out depth type filtration, can also further remove organism in up to standard guaranteeing water suspension.
On the technique basis that the present invention disposes of sewage at traditional activated sludge process, rational proportion sanitary sewage and trade effluent also make it to enter the precipitation from homogeneous solution pond of 33 meters of 4 diameters, in adding hydrochloric acid, precipitation from homogeneous solution pond water outlet with the too high alkalescence of epoxy propane waste water, guarantees that its pH maintains the suitable scope of microorganism; Sewage after neutralization enters one section of biochemical treatment system, compared with traditional activated sludge process, increase inner active sludge circulation link, can farthest tackle like this fluctuation of influent quality and the water yield, and maintain the sludge concentration of Sludge System at normal level, ensure processing efficiency; One section of Sludge System water outlet enters two sections of biochemical treatment systems, on the one hand in higher range, improves biomembranous processing efficiency by dissolved oxygen in system is controlled at; Add clorox and polymerize aluminum chloride in system water outlet place on the other hand, utilize the former strong oxidizing property to remove the ammonia nitrogen in water, utilize the latter to make the fine suspension in water flocculate into piece and finally reach the object of removing suspended substance.Entering fibre turntable filter chamber through two sections of catalytic oxidation sewage after treatment carries out depth type filtration and guarantees that water outlet is up to standard.
